Clearly there is a clear relationship between SETMI and higher forms
of audio intelligence; alien audio intelligence traveling to America
because ( are you sitting on the potty?) higher forms of intelligence
love the taste of Americas music because...... they eat it;
they live off of it. Thats right. Right now aliens are suckling
on Americas music energy and it is a powerful form of nourishment.
Stop and think for one minute.....how would you feel if you looked
like a creepy alien and had to eat bowls of warm solder flux and shredded
aluminum foil three times a day and nothing else...no pizza, no beer,
no sour cream dip, no snacks? And how would you feel if the only music
you had sounded like German grasshoppers playing wind chimes....very
dynamic, low in distortion, but boooring.
Have you ever considered that though ETs may be very smart, they
are also very, very unattractive, boring, have bad breath, and are
so desperate for fun they will travel zillions of light years
just to get a good dose of American funk? Wake up America. Why hasnt
just one scientist or savant asked the most basic questions...Do
aliens know how to party? Are they any fun? Does it bother them
that they are so ugly? Why didnt it occur to just one sci-fi
savant that maybe the UFOs are hanging around our backyards because
they would love some American barbecue? Clearly these creepy big hearted
ETs dont want to hurt us; they want to use us, and because they
are of higher intelligence they know how important it is to strengthen
those from whom they expect nourishment....but aliens are social nerds,
insecure, have never had a great date, and dont know how to
party, and are very depressed.
It was revealed to me that the reason I was being abducted more frequently
was so I could be tested to determine if I had "the right stuff"
for an important mission that I would assigned....no volunteering
necessary. Because I got an "DH/R" on my test (the highest
mark you can get from an extraterrestrial is "DH/R" which
stands for : Dude Human/Righteous, I was chosen to be a servant for
this higher form of intelligence. It was obvious to me that the aliens,
in their desperation to have fun, wanted to control and exploit me
and the Triode Guild. What was their grand scheme? They wanted me
to teach them how to party and how to barbecue!
As you know The Triode Guild Party is the Party of the Party by the
People, and we believe that a government that cant party cant
represent the will of the America people. In addition we believe that
every American man has an inalienable right to a great triode sound
system, a righteous motorcycle, a great hot rod, fine hand made cigars,
a great old worn out leather jack, and all the barbecue and watermelon
he can eat. That is my platform...vote for me, and make America a
better place, by making American men more beaudacous.
Are you still sitting on your potty? Does this article seem much
more interesting now? Now it is time to light up a fine cigar. Now
taste the pralines and cream ice cream with hot baked chocolate chip
cookies, Is this your first time for sitting on the pottty while reading
the rantings of a thermionic techno-shaman in Positive Feedback Magazine
while smoking a fine cigar and eating ice cream and cookies, while
speculating on the question...What is the sound of one 300B clapping?
Get what I mean about the power of the alien mind virus?
I now am introducing you to two very significant alien audiomaniacs.
David Berning and Robert Grunberg are both aliens. You know David,
and soon you will know Robert.
ROBERT GRUNBERG: ALIEN SPEAKER DRIVER DESIGNER
Until now none of you knew Robert Grunberg, because he "accidentally"
came to earth almost forty years ago when a UFO crashed in the desert
of Australia. A newly married couple, Dr. Bill and Ethel Grunberg,
were on an archaeological dig, saw the crash and ran over and noticed
a baby in a diaper and rescued it from the smoldering wreck. They
never told anyone about this weird occurrence and raised Robert as
if he were their own human son.
Soon Robert was showing some remarkable qualities..before we has
three he was pretending that he was a Priest of the Temple of Monkey
Coffins and was making toy monkey coffins...before he was eight he
started to design amazing sounding loudspeakers using phase coherent
Ninja infinite slope double helix Mutant inverted time aligned Turtle
cheese fondue crossovers. By the time he was twelve he was known as
SuperSpeaker, had a pet dog named Woofer, a pet parakeet named Tweeter,
and was able to leap over Infinity IRSs in a single bound. By the
time he was fifteen Robert could dig into the center of the earth
and come back with molted iron which he would mold into magnets in
his bare hands. Sixteen and bored with the Australia marsupial audiomaniac
scene, Robert swam to America and was shocked. He could not understand
the compressed American speaker language spoken. It
was so different than the speaker language spoken on the planet of
his birth..ALNICONIX where all speakers are high impedance, and high
efficiency. According to Robert, the real place of his birth, ALNICONIX
was named after its most abundant "Kudzu" type plant, the
ALNICONA, from which fresh wild alnico magnets can be harvested in
your backyard. I also discovered that beer is made from fermenting
Alnicona, and it has the taste of one 300B clapping.
Life has not been easy for Robert on earth, and he missed the dynamic
yet refined sound of his home planet, but he could not return home.
He was trapped on earth and he became very attached to an earthling
women because her spirit was very much like alnico magnets. So he
resigned himself to the task of making earth more like ALNICONIX,
Since that time he has been working in his lab, trying to create for
earthlings, speakers that sound like they come from another galaxy.
One day last year while I too was on the potty reading the Japanese
magazine, Stereo Sound, I saw an ad for Sunlight Engineering, which
was in Japanese, but there was also a phone number in California.
Why did I stop and pay attention to this ad? I was just doing my job
as Guildmeister of the Triode Guild, which is to hunt in exotic places
for wild audio art on the potty. I now know that the aliens, who abducted
me, were responsible for the strange trance that this Japanese ad
induced. I called the number and spoke to Joe Uyama, who spoke almost
no English, but I think I heard him say that I should call him in
about six months. Because of deep involvement with my Tannoys I didnt
Then the aliens, once again, contacted me in my dreams to make me
focus: A naked Cameron Diaz wearing nothing but a Mickey Mouse Mouseketeer
hat and smoking a Churchill cigar was holding a very large dual concentric
driver while pointing to the hole in the middle. This dream which
was planted in my mind by the aliens meant that if I wanted a dreamy
smoke I should once again call Sunlight Engineering.
WHAT WEIGHS FIFTY POUNDS EACH, IS EIGHTEEN INCHES
WIDE, 16 OHMS, 108 DB EFFICIENT, ALNICO, AND DUAL CONCENTRIC?
As you know from my insistent ranting that I believe that the Alex
Garner designed, Tannoy dual concentric Alcomax driver is one of the
rare works of audio arts. I have cajoled all of you into considering
the unique beauty of "classic" dual concentric alnico drivers,
and many have called me "The Concentric Crusader". Surf
this fantasy with me: We walk into a shop called Concentric and
Sons, which caters to the exclusive custom made dual concentric
audiomaniac trade. All of its products are custom made, like a Holland
and Holland shotgun. A distinguished gentlemen looking like Robert
Grunberg, wearing a white linen coat with very large bat-like ears,
attends to our needs. He offers us, like the typical American audio
dealer, a fine cigar and vintage French brandy as we discuss our musical
taste. We are measured, we write out a check for $9K, and we are told
to come back in six months, when our custom made drivers will be ready.
Get the trip? My fellow dudes do you know the feeling when you have
just encountered a gizmo of immense coolosity...like a supercharged
V-10 Dodge Viper motor? Or when your tailor makes a custom-made suit
for you? Or you commission your design for a 48 wooden sailboat.
That is the Sunlight trip. Sunlight Engineerings 308 driver,
designed by Grunberg, has redefined the concresence of driver coolosity...even
with its flaws. In a flawless world there is no art....which is why
the aliens come to earth.
The Sunlight Engineering 308 (The picture is from the Korean Magazine
Audio plus Music) exists because Robert Grunberg has pushed the boundary
of the "classic American speakers arts" into the next galactic
space/time continuum. At $9,000 per pair without cabinets these
drivers exist to satisfy the artistic cravings of some very intense
triodemaniacs......these speakers were created specifically for the
ultra-triodmaniacs of Japan and Korea, and that means horns.
This driver is to speakers what single ended triodes are to amplifiers...they
both make no sense and they both make the most sublime, and unexplainable
magic. What could be more ridiculous than an eighteen inch paper cone
for midrange accuracy? So let me address their obvious flaws so we
can concentrate on what they do that no other driver I have ever encountered
can do. This driver is designed for a horn cabinet, which means ultra-huge...almost
twice the size of the Westminster Royals, and quite frankly I dont
have the courage, time or money to build them, though you can order
custom made horn cabinets, from my favorite Japanese horn salon, UTOPIA
INSTRUMENT. I put them into sealed enclosures so I will miss the magic
that only horns can create. The woofer crosses over to the midrange/tweeter
horn at 500 cycles , and because of the design of the concentric midrange/tweeter
driver forget the top octave. I am giving up the bottom octave and
the upper most harmonics, so that King Tone can manifest His harmonic
wholeosity in the mid section with a dynamism that is totally unique.
When it comes to critical evaluation I listen to master tapes (Mark
Conese and I make with his custom tweaked Ampex tube tape recorder,
modified RCA ribbon makes with silver Alpha-Core microphone cable)...of
Marco, a great jazz pianist playing the in house concert grand Steinway.
This is the only way to discover the true nature of loudspeakers because
we have eliminated all of the distortion and compression of vinyl
and digital. The output of the Ampex goes directly into the input
of the amplifiers.
I thought I couldnt get any higher than my Tannoy Alcomax high,
and then I experienced these monsters of audio audacity and I realized
once again that a spiritual mature man is a polygamist. It takes two
people to move around this driver, and you are paying for solid gold
magnets. What you will experience here is a degree of aliveness and
harmonic whole-osity that I never knew existed on earth..and I was
right, because this is the first time such a driver has appeared.
This is the driver that has completely redefined the dual concentric
art. This is young David, against the Tannoy Goliath. But of course
these drivers are not something you buy in a store, and according
to Grunberg, he can only make twenty pairs a year. Fear not because
Grunberg is making a, soon to be available, ten inch and fifteen version
of this driver that just may be the answer to unlocking your triode
demons....all 100db efficient, 16 ohm, alnico, dual concentric! Only
you know how long I have dreamed this dream and now it is coming
true, and remember without alnico you cant experience King
Let me make this clear about Robert; he doesnt design loudspeakers,
he designs the raw driver, i.e. the frame, the magnet structure...he
is into the subatomicosity of it all. There are only a couple of earthlings
that have reached this level of mastery. It is a total delight to
listen to Robert rant and rave about magnetic materials, and other
alien driver gibberish.
I believe these drivers may be the ultimate space ship for exploring
the Nth dimension of Music HyperSpace; the existential shadows of
single-ended triodes. These are simple two way speakers with absolutely
the right impedance. They are ultra high efficiency....108 db. They
have what appears to be unlimited dynamics. They have the right magnets,
and they can demonstrate the benefits of ultra simple circuits because
of their dual concentric harmonic whole-osity that is impossible to
achieve in multi-driver designs. Of course these are also the perfect
driver for a 2A3, 45, 50 or 10Y circuit, but for me one watt is not
enough grunt to experience very heavy getting down into the subatomic
rock and roll funk.
I dont know why there is such heavy hedonistic harmonic alchemy
with directly heated triodes and Alnico. Once you experience it you
just cant go back to the cheap ferrite spread because of its
relative coarseness. It is like going from a 300B back to a 6550.
This driver is a very extreme example of this alchemy...it borders
on the type of harmonic hallucinogenic we get when participating in
the ancient Apache peyote ceremonies while waking barefoot over hot
Only this type of ultra-high efficiency driver gives us the ability
of staying in the sweet juice area of the triode; the first few milliwatts,
and have the ability to explode into musical plasmas that capture
our souls. That is why I as Guildmeister, bestowed upon Robert Grunbergs
art a name that accurately describes what these drivers do, that all
others are incapable of doing...only these can be called HARMONIC
PLASMA TRANSDUCERS. Think of this driver as a jet engine
that is spewing forth a gigantic plasma of harmonic energy, and it
is hitting you right in the chest, arms, legs..your entire body gets
caught up in its plasma of hot harmonics. It is like Hulk Hogan harmonics
wrestling you to the ground..
What is true for me is also true for all of you. None of you have
a clue as to the nascent drama of the 300B until you have heard it
with this type of speaker. Even Charles Whitener of Western Electric
does not yet know (in the biblical sense) the dark funky soul of the
300B. Yes, I grant you that mono plate 2A3s and 45s are more subtle
than 300Bs, but I need that real physical juice of music which means
authentic musical dynamics, and the 300B is the perfect mean between
the subtlety 45 and the 845 swagger.... with these drivers. One watt
with this driver will play more dynamically than 300 watts with an
82 db driver.....wake up America...you have it all wrong....but
as your President we will work it out..partying with the party of
And did you notice how many OTL amplifiers were listed in this years
Stereophile Class A Amplifier category? Yikes, and Gadzooks,.... because
all of us know that "normal" OTL amplifier absolutely
must be used with at least 16 ohm speakers for optimum performance
and reliability ....in spite of what OTL amplifier designers claim.
Those who love OTL amplifiers (God bless you all) havent got
a clue until you listen to your amplifiers with speakers like these,
which is why the Quad ESL with its 30 ohm impedance at low frequency
is such a great OTL speaker.
Because I am in a dialogue with Robert and can now speak to him in
the language of his people, I discovered that a FED EX space-transporter
has recently been launched from Alconix. According to Robert, there
is a top secret new transducer on its way to earth that has been designed
for the Guildmiester that is so alien that earthlings will start to
panic when it arrives in American....... in a few months, It takes
about 90 days for FED EX to make a overnight delivery from zillions
of light years away. Stay tuned for this development space rangers.
SUMMARY PART ONE: I am abducted by aliens while eating a lean corn
beef sandwich and channeled to an alien Australian driver designer,
who has taken American Classicism to a higher level, and is connected
to a Japanese audiomaniac who has moved to America to manufacture
his designs for export to Japan and Korea, and the aliens continue
to virus Dr. Gizmos mind so they can take control of his Triode
Guild bid for the Presidency because they need to party.
But because you cant separate the hot dog from the roll, I
now must introduce you to the other piece of the answer; to the other
alien, and it is David Berning. The combination of Robert Grunbergs
Harmonic Plasma Transducer, and Davids new ZOTL 300B single-ended
amplifier is the convergence of two alien forms of genius and what
comes out of the audio oven tastes better than you know what.....even
without the ice cream.
DAVID BERNINGS ZOTL
CAVEAT EMPTOR: I was forced by my alien abductors to begin a "patron"
relationship with David. Because I believe Davids new ZOTL patented
alien thermionic technology will create the concresence of thermionic
musical beauty for legions who would have never imagined it possible,
or affordable, My goal is to convince a high end audio company to
license the ZOTL technology from David so that YOU can buy a ....100
watt per channel ZOTL amplifier, with regulated power supplies, direct
coupled, no bias and balance adjustments, which is NOT sensitive to
speaker load for under $1000. Or what about a 100 watt per
channel one tube (833) directly heated triode singled ended OTL with
regulated power supplies which is NOT sensitive to impedance amplifier
for $6,000 per pair? If I can help make that happen then I deserve
to be your President.
At the Philadelphia Audio Society 1997 annul triode fest I heard
something I never heard before. David, for only five minutes, played
an 811 single-ended triode ZOTL(ZOTL = OTL at the Nth Dimension)
amplifier that had regulated power supplies and weighed ten pounds
for two channels. Yikes! How much less can you get than four tubes
(three input/one output) directly coupled with no audio output transformer?
I was so impressed by this experience I convinced David to let me
help him exploit this breakthrough...which means...I am very biased,
as I should be, because David has shredded the perimeter of the audio
arts in a major way by taking BE VERY SIMPLE, BE VERY STIFF
to its ultimate simplicity and stiffness, and that matters a great
deal to the Triode Guild. I am deeply humbled by his achievement,
while most are intimidated by it.
David ZOTL circuit is such technical wizardry that I will not bother
to discuss it here, because it is beyond me. Davids patent is
the best place to get the technical explanation of his achievement.
Many from the conventional OTL school are claiming that Davids
ZOTL is not a real OTL amplifier because it uses an ultra high frequency
(250K) power conversion transformer to solve the impedance matching
of directly heated triode to speaker impedance. I can understand how
upset these "normal" OTLolgists are and why they claim that
Davids ZOTL has no right to claim that it is a "normal"
OTL...and in one sense they are right, but they are also very wrong,
because ZOTL takes the core primal Futterman impulse to "get
the iron of the audio range" to the highest level of development.
So lets not oscillate over the details, this is not a "normal"
OTL circuit, it is a ZOTL circuit, and Davids patented circuit,
for the first time, solves the impedance problems endemic to all conventional
OTL circuits; lack of stability at low impedances: all OTL amplifiers
are very weak in the bass region. The ZOTL circuit is the first OTL
circuit that doesnt go bonkers into low impedance loads, and
this is the only tube amplifier on the face of earth, since the Futterman
OTL-1, that doesnt have an output transformer and has regulated
power supplies, and ZOTL is far superior in every regard! And this
is a major big deal..THIS IS A DIRECTLY HEATED TRIODE OTL... it
lets us hear the tone of directly heated triodes in an OTL circuit.
This is unquestionably one of the major breakthrough in the
thermionic arts. Those of you who are using OTLs that have video
compactron/pentodes output stages are in for a big thrill when you
hear the totally superior tonal qualities of directly heated triodes.
But rather than rave about this circuit here, just check out Dick
Olsher review in March 98 FI Magazine (also available on this site)
where he puts Davids amazing technical wizardry in perspective.
The amplifier I am writing about now is a different amplifier than
the push/pull amplifier (which uses video compactron tubes) Dick reviewed.
This amplifier exists because I begged David to make the worlds
first 300B single-ended ZOTL amplifier so that I could claim direct
involvement in this historic achievement (never underestimate the
value of narcissism) we would have a new answer to the question...What
is the sound of one 300B clapping", and this amplifier is
an impossible dream come true...it is the convergence of the best
aesthetics of OTL and single-ended directly heated triodes in a single
circuit.... if you can tolerate only 5 watts...it is the
300B single-ended version of the ZOTL circuit. For the only man other
than David who demands regulated power supplies in tube amplifiers,
it was a major thrill to experience this amplifier making love to
the Grunberg art. Have you ever heard King Tone dancing? Take away
all of the audio output transformer anomolies that are inherent in
all single ended amplifiers, take away every last drop of AC filament
hum, add the benefits of regulated power supplies, take away all of
the impediments to linear frequency response at the extremes, and
for the first time you experience a profound new truth about 300Bs
that you can not experience when an audio transformer and unregulated
power supply are choking off its harmonic whole-osity and its capacity
to be explosive with life....you call it transient response, I call
it triode bliss. Here for the first time the harmonic genius of the
300B is completely naked, its transformer shroud lifted, laying bare
its red hot harmonic soul.
MARK MY WORDS: I have seen the future and it is ultra high frequency
switching power supplies with regulators for tube amplifier who aspire
to the thermionic concresence of coolosity. David started this trend
almost two decades ago and now others will soon follow. Remember my
100% batting average.
Because so few have experienced Davids new ZOTL, and even fewer
the single-ended version, it is easy to understand the angst in the
Rec. Audio chat groups. There is much whining and complaining
about this circuit because it is so threatening to makers of conventional
transformer coupled amplifiers and conventional OTL amplifiers, but
let me assure you that like The Harmonic Plasma Transducer, David
single-ended 300B ZOTL is, in the truest sense a breakthrough in the
most serious end of the audio arts. This circuit is not an incremental
step, but a major leap forward in thermionics, is totally unexpected,
understood by few, including me, is totally "untweakable",
and the best reason in the world why others would want to assassinate
David. Who would have imagined listening to a directly heated triode
without an audio transformer? Who would have imagined a single-ended
directly heated output transformerless amplifier....and the elimination
of OTLs impedance sensitivity?
Let me be clear that neither of these products are designed for "sodbuster"
audiophiles. This is ultra serious stuff for those who have been witness
to the thermionic fire; to whose who have walked across the burning
coals, and are living on the edge. This is the place you arrive at
after you have taken Sid Arthurs journey, and know the sound
of one 300B clapping. If you have any doubt about Davids alien
genius just consider this...in a ten pound box David is able
to create what it took the savants of New York Audio Labs to accomplish
in a 250 pound form of the Futterman OTL-1. After listening to ZOTL
when you pick up the box, which weighs less than you preamp, your
brain goes.....Duh! How is this extreme level of anti-gravity performance
possible my fellow earthlings?
Let me address this issue of OTL aesthetics which is never discussed
because so few have the vast experience (kissing myself in the mirror)
that I have with so many different OTL circuits. OTL amplifiers because
of their impedance sensitivity can be very right or all wrong.
OTL amplifiers, contrary to what Bruce Rozenblitt asserts, can and
should not be used with "normal" speakers because OTLs are
not "normal" amplifiers. They will create a completely unique,
amazing clear and wide sound stage but the dynamics are often non-linear
because of their extreme impedance sensitivity. The
higher the impedance of the speaker the less prone OTL amplifiers
are to this dynamic discontinuity. Since the 1970s I have ranted that....you
havent got a clue about just how good OTL circuits are until
you hear them exactly the right way with regulated power
supplies and high impedance speakers. Most OTL designers dont
use regulated power supplies because they dont know how to design
them properly. Regulated power supplies, to a great extent, heals
this OTL dynamic disproportionality problem. The ZOTL circuit, because
it does not suffer with this impedance sensitivity and because it
has regulated power supplies for the first time reveals the nascent
and unexploited capability of tube amplifiers that have no audio output
transformer. Bernings ZOTL is able to reveal the subatomic
harmonic coupled with dynamic righteousness. I have never heard this
combination before in any OTL amplifier, and Dick Olsher agreed.
But I must constantly remind you that the single-ended ZOTL amplifier
requires the finest high efficiency speaker to appreciate its capability.
Those of us who are on the single-ended path know this true to be
self-evident: once you hear the clarity and wholeosity of these circuits,
even the best of the best push/pull amplifiers sounds harmonically
awkward. We are prepared to accept the flabosity of the bass, and
the anemic upper octave for single-ended midrange scroopulosity...it
is the price we gladly pay for King Tone. Single-ended maniacs are
hunting for that hallucinogenic harmonic transparency, and for this
hunter ZOTL, in this single-ended format, has taken me to a very exotic
harmonic happy hunting ground...one that I never knew existed, because
I now experience all the virtues of single-ended circuits without
their limitations, and that is my definition of triode heaven....and
it is driving 108db efficient, 16 ohm Alnico dual concentric. Long
Live King Tone.
The point being, dont forget that there is an alchemy between
the Grunberg alnico transducer and the Berning 300B ZOTL, which is
the alchemy of alnico and directly heated triodes.....you need
one to fully fathom the other. For those who grock, as I do, having
as many different answers as possible to the 300B question, this circuit
is a must have for your collection because it reveals a 300B truth
that no other transformer coupled circuit can express. For those who
live by...Be Very Simple, Be Very Stiff...this is as about as simple
and as stiff as you can get.
Let me mention this to triode savants who wrestle with the noise
dilemma of directly heated triodes...the signal to noise ratio of
ZOTL is minus 120 db which must be an all time low for any directly
heated triodes, and this is probably why there is such an errie quality
to its harmonics...all the power supply hash is gone because of Davids
totally cosmic high radio frequency switching power supplies, which
are nothing like the cheap switching power supplies used in cheap
transistor amplifiers. This amplifier can not work with all 300Bs
because of variation in filament wire inductance, so check with David
for the rules of tube swapping. David uses Western Electric 300Bs.
Again this amplifier can not be tweaked.
What is the down side of this amplifier, and this should not be overlooked?
It is too transparent. It reveals too much of the subatomic harmonic,
and if you input and associated equipment is not of the highest quality
you are simply not ready for ZOTL. Listening to our Ampex tube tape
recorder masters is the most amazing thrill I have ever had, but when
we connect the CD players we are hearing more digital discombobularity
not less. Because ZOTL does less filtering than any amplifier I have
ever experienced it will upset your systems equilibrium, and
may force you to rethink all of your inputs including cabling. I want
to suggest to you that this is the ultimate amplifier for judging
digital equipment. This amplifier must be used with silver cables.
But what is the messianic nature of ZOTL and why are so many thermionic
artisans getting unstable over it? How would you like to listen to
a.... 45,50, 2A3, 845 or 805 or 833 in a ZOTL single-ended circuit?
What do these tubes sound like without an audio output transformer?
What would a Western Electric 212 ZOTL sound like? ZOTL solves the
fundamental artistic limitation of high powered single-ended circuits...because
you can use any of these tubes without that big chunk of iron. Get
what I mean about the potential of the ZOTL circuit? An insight may
be found in the most amazing experience I had listening to the Svetlana
811 in the ZOTL single-ended form...which shook me to the foundations
of my thermionic being.
None of Davids amplifiers are cheap. He builds them one at
a time in his home. They are extremely reliable, and all I can say
is....a new door has opened...are you ready to go through?
SUMMARY PART TWO: David Berning is an alien thermionic audio artist
and is proving to us earthlings that the impossible dream is possible...the
unique aesthetics of a directly heated single-ended triodes and an
OTL amplifier can be merged into one circuit with regulated power
supplies, no speaker impedance weirdness, and only weigh ten pounds.....proving
that higher forms of thermionic intelligence is ready to make contact
CONCLUSION: Very gifted alien audio artisans like Grunberg and Berning
are inventing new tools for us to explore the classic questions of
the audio arts....like,.. What is the sound of one 300B clapping?
But on a more profound level these alien audio wizards confirm the
eternal cycle in the arts...just as we thought we had reached a concresence
of musical beauty, the next door is shoved open and we behold a glory
that we never knew existed before, and it is in a form that we never
imagined, and yet it looks very familiar....the timeless paradox of
the audio arts shinning in you....and you can never be too rich, too
thin, and use too many different types of 300 B amplifiers....with
high impedance, high efficiency Alnico dual concentric drivers. The
thermionic future is much more than you imagined because it is much
less than you imagined.
