Decware Zen Torii Tube Stereo Power Amplifier MKIII / EL-34 / USA / New

We're Celebrating Our 13th Year On eBay!!!!


Spectacular Tube Amplifier Made in the USA!! We actually have two but this auction is for one of them.

This amplifier is new! Purchased in 2010, but never put into service because it's owners busy work / travel schedule.

Taken out of it's custom flight case (included) and tested for 1 hour.

100% functional. Tubes are brand new. (Because tubes have not been fully run-in we can't and won't guarantee them to be problem free)

Included:
Amp, Power Cable,
Tubes, Tube Boxes, Flight Case , Copy of owners manual
Not Included: NA
History: Single audiophile owner, non smoker
Physical Condition: As new from factory, Wood base seems to have come from factory with a few minor knicks
Working Condition: Fully Functional (tested for 1 hour)
Voltage: 120v, 60Hz (We do not convert to other voltages, but we believe this can be converted)
Shipping Weight / Shipping Method: Aprox 45 lbs - Contact us for a shipping quote

From Decware:


Having such a simple signal path gives the Zen TORII the same transparency as our SET amps where only 2 resistors and 1 capacitor are seen by the signal.  And to complete the picture, we use no negative feedback, which is easy to do if you're building a Triode based amplifier, but the Zen is a Pentode design that forgoes the mediocre "ultra-linear" technique of maximizing the tubes power and smearing it's clarity.  Instead we make our output transformers to compliment our tube regulated power supplies - which is the only other gimmick-free way to get linear response from a pentode without using destructive negative feedback. Of course it's far more expensive to do it this way, and makes less overall power which is why you don't find it on the vast majority of hi-end amplifiers. 


The Zen uses a unique push-pull design that employs only a single capacitor and gain stage to drive the output tubes, just like our popular 2 watt S.E.T. amps.  Add to that the cleverly simple way it preserves the even order harmonic content and you have a push pull amplifier that is truly unique in the market...  It has the beauty of S.E.T. sound with the performance of the very best push-pull.  Speed and attack are taken to a new level here.  In fact, the Zen TORII makes most 200 watt solid state amps sound weak.





Dual mono design with a power supply for each channel to preserve stereo separation and dynamics.
Tube regulation to filter off the harmonics and artifacts from the power supply giving you 100% grain free sound with jet black backgrounds.
Trim control on each channel so you can adjust the tightness of the bass perfectly for any given loudspeaker.  It does this by putting the voice coil of your loudspeaker in parallel with one of the resistors inside the amp so that the loudspeakers fluctuating impedance can tell the amp to put out more or less power.  It does this in real time, nearly at the speed of light.
Trim control on each channel for the treble.  This allows you to adjust the top end this amp offers so that virtually any loudspeaker can sound right, be it a Lowther full range driver or your favorite hi-fi speaker.
Two pair of input jacks and a master gain control.  This means you can hook two sources up to the TORII MK III and use the master gain as a volume control making the use of a preamp completely optional.
CCE mod, a Decware breakthrough in 2009 that turns the EL34 output tube into a super tube.  Forget about paying $900 for exotic tubes, the EL34 - an already famously good sounding valve - is the only popular audio pentode of this size that does not have the extra grids internally connected.  The CCE mod, aka Hazen grid mod, virtually eliminates the universal problem all tubes have of stray electrons bouncing off the plate for stunning clarity.
Self biasing. While it can use your choice of KT88, KT77, 6550 or EL34's, there are no worries about adjusting the bias - ever.  Tubes last for several years in this amp and there is virtually no maintenance.  All you ever have to do is turn it on and enjoy music.
Proprietary USA made power and output transformers.  Designed with the best grain oriented silicon steel cores and meticulous interleaving you can be sure that those who copy the TORII with off the shelf transformers will not have the DECWARE sound.
Hand constructed and soldered from start to finish by a single person. It's using top grade components, switches, connectors, gold sockets and silver wire all soldered together with the absolute minimum number of nodes.  There are no circuit boards.  These amps are fine example of American made ART and could never be built like this were they to go into mass production.
