"I'm not sure if this is a time machine, a spaceship, or something that you plug in like a glowing gate to a higher plane of consciousness but every time I listen to it I disappear!"

The TORII is one of those rare amplifiers that can liberate even the most fanatical audiophiles from the buy and sell marry-go-round.


It does this by getting everything down to the last detail... right.  The kind of "right" that goes WAY beyond it's impressive specs or appearance.  It was created BY human ears FOR human ears.  With the Zen TORII, you can see better with your eyes closed.


One of the reasons it can do this is because like a Stradivarius violin, each amp is hand voiced down to the finest details. For the same reason a Stradivarius sounds superior to mass produced violins, the Zen is simply untouchable by mass produced amplifiers - regardless of price, unless of course you're into being pummeled by loud obnoxious and uninteresting amps with huge power figures.  The Zen is for people who want more than to just hear the music, they want to float in it.  It's a goose bump machine if you know where I'm coming from.

This amplifier absolutely captures the magic of single-ended triodes, yet it isn't one. Over twenty years in the making, it's out-of-the-box design theory and tedious (hand built) execution give it a sound that simply embarrasses many hi-end amplifiers and is to date our best work.

I should also mention that this amplifier is made in the USA with our own hands. It's using proprietary US made transformers (real good ones) and even the T6 Aluminum powder coated chassis and hardwood bases are US built.

This is a pretty ballsy 25 watt per channel amplifier that features 2 pair of inputs with an input selector switch and a volume control.  It works perfectly well WITH or WITHOUT a preamp. It's at home with most hi-fi speakers and equally poised with high efficiency speakers due in part to it's complete lack of noise or hum.  There is also a high frequency control outside the signal path that lets you adjust the top end of any loudspeaker to your liking.  Along the same theme it has a bass dampening control that lets you adjust the bass character of your loudspeakers to eliminate room boom automatically and add or remove weight.

This pure class A tube amplifier with no circuit boards also features a dual mono design with fully independent vacuum tube regulated power supplies.  It's using tube rectification on each channel feeding a mirror imaged push pull layout with no negative feedback and is fully self biasing.

It's an easy amplifier to own because there is no maintenance and no bias pots to adjust.  The tubes are not run hard and consequently last about twice as long, are easy to find, not overpriced and the ONLY tubes that can take advantage of the Hazen Grid Mod. Something that no other triode (like 300B's) or Tetrodes (like KT88's) can do.

You will simply turn it on and enjoy the music, every time. 


The TORII uses the famous EL34  / 6CA7 output tube which is the only popular audio tube with all it's grids separately connected.  This means the TORII has complete control over each of these grids and can for lack of a better phrase - Have it's way with them.  The result is a mid-range transparency and better sense of timing not obtainable with anything else. 


This amp can run speakers between 4 and 16 ohms. 








If you like contemporary styling, the TORII is also available in a variety of beautiful hardwoods.  You can configure your amp from our shopping cart.  The solid walnut shown below is available at no extra charge.

It's no secret the in the world of exotic tube amplification that S.E.T. amps rule in transparency and liquidity.  We've all heard statements like... "female vocals to die for"  or "insane imaging" when describing these jewels, but in the same breath you'll also hear things like "needs an easy to drive speaker" or "while the bass is good, it lacks the absolute control and dynamics of the bigger amps."  So right away you're left with a compromise... performance vs. musicality and grace. 

S.E.T. amplifiers are what motivated the design of the Zen TORII

...because any time you have between 2 and 10 gloriously transparent watts the only thing that could be better is more.  Designing a high power S.E.T. amplifier requires adding another gain stage (tube) or paralleled output tubes (or both). Either one causes a loss of transparency when compared to a single output tube per channel.

In the Zen design, even though you have two tubes per channel, they are not in parallel but rather transformer coupled in series so that only one tube is really in the signal path at any one time.


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. 



Tone Audio Magazine"After hundreds of hours of initial listening, the Decware Zen Torii continues to improve, as designer Steve Deckert said it would.  While the full review will be in issue 41, suffice to say that this is one of the most musically engaging amplifiers I’ve had the pleasure to experience.  If you’ve ever spent time with a great SET and thought “If this only had 2-3 times the power, I could live with it,â€? your ship has arrived.  After owning a number of the world’s finest SET amplifiers, I can easily support Deckert’s claim that the Zen Torii is certainly the equal of any SET I’ve owned."

-TONEAudio Blog / JULY 26 2011








How do you get an amplifier to sound like it does at 2:30 A.M. (when the power is cleanest) during the day and virtually every time you listen to it?  Tube voltage regulation designed to filter instead of regulate.

First of all, the vast majority of tube amplifiers for sale do not even have tube regulation.  Not to mention the obvious... but just because an amplifier has tube regulation doesn't mean it's going to sound better.  Tighter and more control, yes.  Better? ...not often.  The classic shunt regulation so often seen in tube amplifiers that do offer it, often poisons the transparency with injected noise that must be further filtered.  The Zen doesn't need tube regulation to improve power supply performance. It features a dual mono design with oversize power supplies, one for each channel.  It's a brute force approach that delivers over 300 ma. of current when less than half of that is actually used by the circuit. 


In this special amplifier the Voltage Regulation tubes are wired in series with the load. In that configuration they become a filtering device instead of a regulating device.  The VR tubes place a measurable vacuum gap between the load and the power supply.  This creates Ultra Clean Power because all of the the noise is filtered off.  (Noise from pollution in your local power grid that includes the harmonics that ultimately end up at your wall outlet and in your amplifier.)

This hash and grain that poisons virtually everyone's audio gear is eliminated in the Zen TORII.  It literally doesn't make the jump across this vacuum gap between the cathode and anode of the VR tubes.  Talk about black backgrounds, we could call it the grain eliminator or the liquidity insurance program, or just an unfair advantage over virtually all of our competitors.

This is one of the reasons why we know that unless you own and use a power generator, like the PS AUDIO power plant as an example, there is no way your present amplifier will sound as good as a Zen TORII (...assuming all else was equal and even that's unlikely.)  And if it wasn't enough to do it once, we employed this technology on every stage in the amplifier and independently for each channel.  That's a lot of GLOW from these beautiful tubes that don't even get hot or wear out! 

You won't find tube regulation in the vast majority of power amplifiers, and none that use it in this critically important way.  Yet, impressive as it might sound it is only a small part of why the Zen TORII can achieve the unique sound quality that is has.








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.


EVEN ORDER HARMONICS ARE WHY SINGLE-ENDED AMPLIFIERS SOUND GOOD.

The Zen Torii has unique harmonics giving it a sound unlike virtually all push pull amplifiers, solid state OR tube.

The harmonics of an amplifier can be revealed in the distortion measurements.  There are two types of harmonics;  Even order harmonics and Odd order harmonics.  Musical instruments naturally create lots of Even order harmonics. So do single-ended amplifiers btw.  However, I can't think of too many things in nature that create sound with Odd Order Harmonics, except for solid state and tube push pull amplifiers!  This is why you don't get an organic sound from these types of amplifiers, and why everyone is so gaga over Single ended designs.


Here is a distortion graph of a typical push pull amplifier:


This works by simply playing a single tone at 1kHz and measuring the echo!  You can see that the first harmonic (A) is at 3kHz - an ODD number.  The next (B) is at 5kHz and the third (C) is at 7kHz.  This is what an ODD Order Harmonic signature looks like.  Notice there is no even order content whatsoever.  Also of interest is the average noise floor seen between the test signal at 1KHz and 20kHz is about -110dB.  (larger numbers are better). Considered very good this noise level is brought to you by a Balanced XLR solid state push pull power amplifier.

One of the main reasons why push-pull amplifiers never sound like good single-ended triodes is because most push pull designs naturally cancel the even-order harmonics as clearly shown in the graph above!  Below is the Zen Torii's graph, where you will find the missing Even order harmonics at 2kHz, 4kHz, 6kHz and so on, yet it IS a push pull design!

And an opportunity to make a point - the Zen Torii is also quieter than the solid state amp in the same 1 ~ 20K range - coming in at -125db!



Here is the superior sounding distortion graph of a Zen TORII:



So you can see in the explanation above why the Zen Torii responds like a single ended amp and why other push pull designs sound far from it. Having the power and control of push pull, something no S.E.T. amplifier really has, the TORII gives you the best of both worlds.


Tone Audio Magazine"DecWare founder Steve Deckert proudly proclaims the Zen Torii is “the last amp you’ll ever want.� And if you agree with Nelson Pass’ theory that there is a best amplifier for each type of speaker, the Zen Torii could be just “the best� if you have the right speakers. TONEAudio publisher Jeff Dorgay was smitten enough to purchase the Torii for his reference fleet of amplifiers. For an EL- 34-based amplifier, the bass grip is nothing short of breathtaking, and the Torii renders musical detail like Kodachrome 25.
Indeed, there’s never been a better example of specs not telling the whole story. The Torii plays louder and interfaces with a much wider range of speakers than suggested by its modest 26-watt- per-channel rating. Showcasing old-school style, the Torii is hand-wired in Illinois by the DecWare staff and guaranteed for life. American craftsmanship at its finest."

FULL ZEN TORII REVIEW HERE













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.

This amp is shipped with hand graded premium quality EL34/6CA7 output tubes, N.O.S. voltage regulation tubes, OA3 and OC2, Russian 6N1P (6922) input tubes and 5U4 rectifiers for each channel. This factory tube compliment is ideal for your evaluation and even though you can "roll" different tubes through it, you certainly won't feel like you need to!

The TORII has been optimized for EL34's with its Hazen Grid Mod.  It is however possible to use other tubes, such as KT77's or 6550's or KT88's but none of these will have the ability to activate the Hazen Grid circuit.  Still it offers an opportunity for different voicing if you enjoy trying different things.

The input tube is a single 6N1P or 6922.  The 6N1P's have the warmest tone, 6922's tend to have more speed.

The rectifier is a 5U4G and can be substituted with a 5AR4, 5YGT or compatible rectifier.  Each rectifier change will also make audible differences in the sound and performance of the amplifier.

Voltage regulators can be ignored, or used to take the tube rolling experience to a deeper level. The four voltage regulator tubes below all modify the operating points of the output tubes they regulate. This in turn changes the way the output tube sounds.  For example:


 OA3

OB3

OC3

OD3


You can use an OA3 which gives the highest grid voltage and usually the most low end performance.  You can use an OD3 which gives the lowest grid voltage and usually the tightest bass.  If you wished it to land somewhere in between, there is the OB3 and OC3.

The smaller seven pin regulating tubes clean the power for each input stage.  There are also four tubes you can use here, starting with the stock OC2 also know as VR75.  This gives the input stage the highest gain.  Changing to a VR150 lowers the gain of the input stage.

With the stock tubes we ship in the amp, you get ideal performance in most applications. 
It's just that you CAN tweak a TORII to a very fine level if so motivated.

The Zen TORII has impressively flat frequency response.  In the range of human hearing it is accurate to within 0.4 dB  This is a real world frequency response measured through loudspeakers at normal listening levels.  It is not a simulated response nor is it the typical measurement where the amp is hooked up to a purely simple resistive dummy load instead of a complex loudspeaker load.

frequency response both channels

Frequency response of both channels overlapped.  Tone control at 1/2 way point. 
The minus -3dB point at low frequency is 6Hz.


OUTPUT TRANSFORMER COUPLING

The Zen is a very stable amplifier capable of driving all but the most power hungry loudspeakers because of it's transformer-coupled output stage.  This creates a hand-shake between the amplifier and the loudspeaker and protects the speaker from DC voltages should a tube ever fail.  Of course most tube amplifiers use output transformers, which tend to be the most expensive single components in the amp.  This is where most amplifiers fall short by trying to impress you with big heavy transformers of average or low quality.  The more power the amp has, the more likely it is to use moderate quality transformers - at best. 

Decware transformers were designed and are built specifically and only for THIS amplifier.  They use the highest quality grain-oriented silicon steel laminated cores with exhaustive interleaving to produce the most phase coherent wide bandwidth sound possible.  Our transformers have always been proprietary and are a big part of the secret behind the Decware sound.


VOLTAGES

This amplifier comes standard with our World Voltage Compatible Transformer. Your amp will be automatically wired for the correct voltage for your country and be supplied with the correct removable power cord. 








The Zen TORII has some options. 




You can select from the Black Figured Base (shown at the top of this web page) OR the Contemporary Style Base (shown above).  Different woods can be selected from the shopping cart.  The Black Figured base is only available in Black.




There are also some knob choices.  From left to right are Ebony, Gold, Black, Cream, Walnut.  You can configure your Torii with the knobs you want from within the shopping cart.


ADDITIONAL OPTIONS

When available, can also be configured by simply adding your amp to the shopping cart and checking the boxes you want.  The options include things like a Stepped Attenuator in place of the Volume Control and even VCAPs, a popular high dollar coupling cap that many audiophiles request.  No options are needed to experience the flagship sound of the Zen Torii, they are options, not suggestions or requirements.





OPTIONAL SPARE TUBES

We are now also offering a matched quad of the Shuguang 6CA7 Grade A Treasures
(OUTPUT TUBES) as an optional second set of tubes for your Zen TORII.  You can select the option from the shopping cart.


OPTIONAL SHIPPING CASE

If you travel, or just want a bomb-proof case to put your TORII in, we have this custom fit case available.  Your amp can be shipped in one.

This Military-grade waterproof/shockproof case customized to perfectly form-fit your amp for transport and or shipping.  The amp fits upside down into foam. 


Torii Case SKB 3I Series Injection Molded Mil-Standard Waterproof Cases are molded of ultra high-strength polypropylene co-polymer resin, featuring a gasketed, water and dust tight, submersible design (MIL-C-4150J) that is resistant to corrosion and impact damage.

Features a continuous molded-in hinge, patent pending "trigger release" latch system, comfortable, snap-down rubber over-molded cushion grip handle, automatic ambient pressure equalization valve (MIL-STD-648C), resistance to UV, solvents, corrosion, fungus and impact damage (MIL-STD-810F).

  
Case features wheels and a pull out handle so anyone can easily move it.



OPTIONAL VCAPS

Decware has it's own time coherent polyurethane film & foil coupling caps made to the FKP-1 specification by WIMA in Germany.  These are standard in all Zen TORII's.  Since many audiophiles are unfamiliar with our caps (we don't sell or advertise them) they ask about "possible upgrades" for these caps and list of a whole host of boutique audiophile caps they think may sound better.  Virtually all of them have been tried in house, and most are at best a sideways move, many sound worse.  The ONLY cap we have found that we feel is justifiably better than our stock offering is the Teflon Tinfoil VCAP's.  These are expensive.  They make the amplifier custom and non-refundable. 

Break-in times with VCAPS are 10 to 20 times longer than Decware's stock caps.  During that break-in time VCAPS will typically sound much worse than Decware's stock caps.  And considering most customer's report a noticeable improvement at 500 to 600 hours, it seems to be unanimous that audio nirvana is not experienced until the 1000 hour mark.  However, once you've got them broken in, there just isn't anything out there better. 

VCAPS or any available option for a Zen TORII can be done at any point during your ownership of the amplifier.

A few Customer Comments...


"I know the amp will only get better with time, but i can tell you now, my friend... you didn't just hit a home run with the new torii, but rather a grand slam.  Congratulations on a beautifully done amplifier."

-George K. Irvine, California USA



"This Torii is giving everything I was hoping it would give to my music listening.  It really is the most transparent thing I've ever used to date.  A very satisfying amplifier in my system and a delight to listen to."

-Chris M. Underhill, Vermont USA



"This amp has an almost eerie sense of musical realism! It has the clarity, sweetness and holographic imaging of great Single Ended Triode amps but with commanding weight and power. If you thought bass was difficult with tubes, forget it. The TORII resolves bass as brilliantly as it coaxes its lifelike mid-range and natural, airy highs from recordings."

-Will R. Santa Fa, New Mexico USA


"I will send you a fully thought out review with some more hours on the Torii but just wanted to drop you a note to say how amazed I am at the amp and how it has transformed my system.  You could charge 3 times the amount and be right in line with market value.  But that is not the case here, this amp is better that the products I have owned from Pass, Krell, Rowland and even blows away my Atma-Sphere amps.  And this is with just a day and a half break in.  There is something just plain right about what I am hearing.  Bless you for bringing music alive!"

-Walt R. Gardners, Pennsylvania USA



"As the centerpiece of one of my company’s flagship systems, the Decware Zen Torii has pretty much killed the audiophile in me. I am now a simple a music lover. Its presence marks the first time in over twenty years of serious listening that a particular thought has crossed my mind: I have no reason, no itch, no desire whatsoever to upgrade this system. I am baffled that this level of immersion and enjoyment can be had for so little. But even more telling is that it has made me want to explore musical genres I had never given any consideration to. And that’s an even greater testament of its virtues."

-Frank D. EarHead Audio, LLC Winchester, Virginia


"Well, I really don't know what to say except that this is one amazing amplifier. If had it on most all of the daytime since it came in and while the sound is still changing as the amp breaks-in it seems to be settling in nicely. This amp already sounds miles ahead of anything I've had in my system. It sounds much "bigger" than my current 200 wpc amps. How you get a 25 watt amp to sound like this is what I'd like to know.

This amp (compared to my current 200 wpc, class D amps) has MUCH better weight, tonality, pitch definition, better extension and clarity in the treble. Grain/glare are non-existent with the most natural detail that I've heard. Dynamic contrasts are much better than my current amp - classical music is exciting to listen now. And as your web page states the detail is there in the music from an extremely low level without turning it up. I seem to have plenty of gain and I've yet to clip the amp even listening at (to me) pretty decent levels with my Merlin VSMs. I've owned the VSM's for about 10 years and now I know that I really had not heard what they can do.

I've had quite a few pieces over the past 25 years: Audio Research, Music Reference, VTL, Atma-Sphere and most recently my only venture into solid state: a Channel Island D200 Class D amp. Your amp is far and away the best I have ever heard in my system (I had the Atma-Sphere amps for 10 years and know very well what they sound like) and I will certainly not be sending it back. I really wish I had a way to communicate to other Merlin owners how well this amp seem to work with these speakers. Thank you for an outstanding product at a very reasonable price."
