Ayon Epsilon EVO Mono Amps - Pure Class A - Pentode/Triode Operation!

Pure Class A Pentode/Triode - 

NO Ultralinear/Triode Class AB1 

NO Ultra-Linear/Triode Operation – You do not want this mode of operation in your Tube Amp!

The Holy Grail is Pentode/Triode Pure Class A

No, we do not use ultra-linear/triode operation – Inferior for High End

Ultra-linear electronic circuits are those used to couple a tetrode/triode or pentode
vacuum-tube to a load (e.g. to a loudspeaker).

‘Ultra-linear’ is also known as ‘distributed loading’; a circuit technique patented by
Alan Blumlein in 1937. Ultra-Linear “distributed loading” was intended
for guitar amps, etc.

• In pentode or triode, in which the screen-grid is connected to a stable DC voltage so there are no signal
variations on the screen-grid (i.e. the screen-grid has 0% of the
plate’s output signal impressed on it), or

• In triode, in which the screen-grid is connected to the plate (i.e. the screen-grid
has 100% of the plate’s output signal voltage impressed on it), or

• a blend of triode and pentode, in which the screen-grid has a
percentage (between 0% and 100%) of the plate’s output signal impressed
on it. This is the basis of the Ultra-Linear “distributed load circuit”
and is seen as a form of feedback, which alters the behavior of the
electron stream passing from cathode to anode.

Ultra-linear introduces negative feedback, which squashes and compresses the sonic performance. 

So the Pentode/Triode operation will yield a vastly superior response and
more of a “tactile” or SET sound, more of a three dimensional sonic
signature. Quite Superior!

European Made - Austria

40 years in High End Audio - Ayon manufactures the finest vacuum tube audio equipment. 

Bottom line only the USA, Europe & Japan manufacture the finest in high end audio electronics - We have offered gear from Asia - Japan not included.

A total disappointment and a complete waste of time. Poor quality and poor sonic performance not to mention the excessive defective rate.

Axpona 2018 Show - Ayon Audio & Lumenwhite
AXPONA 2018 - My Top Room for Sound 04-20-2018 | By Robert S. Youman |

From the moment I took my seat I was quite comfortable if not spellbound.

Bottom line, the sound quality was simply outstanding.
I was extremely impressed with the rich harmonic presentation of this system. There was just a natural liquidity and flow that could not be ignored.

USA Tube Audio’s demonstration of the new Lumen White 25 Generation 4 speakers driven by Ayon electronics was spectacularly great, with wall-to-wall soundstaging. 

Close your eyes and you’d never know that you were in a hotel room.

Ayon Audio
Ayon Audio distributor USA Tube Audio presented the world premier of several new Ayon products; I’ll cover just the amplification. The system included the Ayon Spheris III preamplifier ($34,500) or alternately, the S-10 Network Streamer/Preamplifier ($8300). The all-tube components, housed in gorgeous chromed chassis, fed a pair of Ayon Orthos XS Gen 4 mono amps which drove the new Lumenwhite White Light 25 Gen 4 Anniversary speakers in one of the show’s best-sounding rooms.

Most Surprising was the stunning Lumenwhite “White Light Anniversary ($69,000).  

Lumenwhite White Light “Anniversary” 
Do blondes still have more fun? If it’s a wood-veneer finish, Lumenwhite certainly thinks so. It premiered Generation 4 of its famous “White Light” speakers—the White Light Anniversary Reference ($69,000). The Anniversary Reference features the world’s first all-ceramic driver array in a radically advanced “pressure-and-flow-dynamics-optimized cabinet,” with numerous innovative technologies in an all-out assault on the state of the art in reference loudspeaker performance. Sonics were brilliantly fast and open. To my ear Lumenwhite’s latest generation of ceramic transducers was uncolored and possessed terrific dynamic output as well as sensitive micro-gradients. Driving the White Light were all Ayon components including the vacuum-tube CD-35 SACD streamer, S10 vacuum-tube streamer, Spheris tube preamplifier, and Orthos II Gen 4 mono amps.

Gold-plated heavy duty binding posts and input jacks DC-Power filter AC phase polarity control indicator Chassis finish: black / chrome The bias setting controls the current, thereby the operating point of the tube and therefore is vital for its lifetime and sound. 

With the bias, the power amp can be tuned to cooler/cleaner or hotter/more impure; in the latter case, the amp has more punch and can be overdriven more easily. However, too high a bias leads to faster wear of the tubes. For tube amplifiers, an "automatic" bias control of the power tubes would be advantageous because differences, aging, or voltage shifting could be compensated more easily or reliably. 

Furthermore, the customer needs not care whether the setting of the bias value is correct. Unfortunately, this desirable automatic device has serious disadvantages such as significant deterioration of sound and power. Creating a new automatic "fixed bias" circuit controlling the operating conditions of the power tubes reliably in the specified way WITHOUT negative influence on the sound or output power respectively was a very serious challenge for the Ayon development team. 

This intelligent Auto-Fixed-Bias system must not be mistaken for a semi-automatic or so called fully automatic bias fixture which can never achieve a result comparable with the new Ayon Auto-Fixed-Bias circuit. The Ayon Auto-Fixed-Bias circuitry delivers the best possible combination of sound properties, measured power and usability because it does not operate during music listening. This system does not result in deterioration of sound, loss of output power, or any other negative concomitants. 

Additionally the Auto-Fixed-Bias system is equipped with a sophisticated electronic two-way-protection circuit which is always active during the tube test program or the switch-on period respectively. In case of excessive bias current or a defective tube the high voltage is switched off immediately either by a photo coupler controlled "over-current-sensor" or by an analog-digital-converter. These protection circuits do not lie in the signal path.
