The Mini Torii was designed as an amplifier to be used in an exotic hi-end desktop system where physical size is a consideration. Of course we knew going in that it would also do favorably as the center piece of many listening rooms.

One big feature that makes it unique is the way it creates it's own clean power with glow tubes. No one has room for a power re-generator on their desktop, but we needed the same or better performance. By using glow tubes to store and release power across a vacuum gap, all the noise and crud in your power line is blocked or lost in the gap.

The Mini Torii uses four of these unique tubes to filter the power feeding both the input tubes and the output tubes separately. The result is a liquidity that you typically don't achieve without spending thousands on power conditioning.





Single-ended integrated amp design featuring two volume controls and a selector for two sources.

Has enough range on the volume control that it can be driven directly from the headphone jack of your computer, tablet, or smartphone and sound better than you except giving it great flexibility. Of course the fidelity of this amplifier deserves the best source you can afford but in the real world you may find yourself using either or both.

There is also an adjustable treble cut with a bypass switch so that if you find yourself streaming compressed MP3 music to it, you can make it more tolerable by reducing the very top end where the jitter is most apparent.

Dual Mono design gives it a separate power supply and even a separate power switch for each channel. Basically it's two mono-blocks stuffed into a single chassis. This enhances performance and makes it easy to to troubleshoot any tube problems you might have.

  • Treble adjustment with bypass
  • Adjustable feedback to control presence
  • Our Proprietary UFO wide-band output transformers
  • Easy to move around
  • High mass powder coated steel chassis
  • Solid hardwood base with wood options
  • Enhanced tube life
  • Self-biasing - nothing to set or adjust
  • 4 and 8 ohm speaker switch
  • Cryo-treated Beeswax caps
  • Highest grade internals
  • Output tube compatibility facilitates custom voicing


The Mini Torii is basically the most exotic tube amp you can squeeze into a package this small. It's sound and build quality consistently exceed everyone's expectations... which are quite high.





Shown above is the Mini Torii's Glow tubes used to clean the incoming power.

Shown below is a rear view in our standard walnut base.









There are a few options available for this amplifier that can be selected from within the shopping cart.





Select Voltage: Choose the voltage for your country. The appropriate power cord will be selected for your location and included with the amp.

Base style: The standard base is natural walnut. Custom woods can be selected for an up charge.  Exotic woods would be anything not listed, like for example; Zebrawood.  Just write in the kind of wood you want in the comments section of the order.

Volume Control: Smooth action volume controls are standard and allow for better adjustability. Our stepped attenuators feature a 20 position gold contact switch with precision 1% resistors allowing the volume to be adjusted in steps.

Headphone Jack Type: No headphone jack is standard, however one can be added.  It's located in the front and is available in 1/4 inch TRS standard format only.  The headphone jack option works well with planar headphones.

Knobs:
There are three controls on a Mini Torii... Left Volume, Right Volume and Treble shunt.  Below are your knob choices for these controls.  You can select the knobs from a list when you add to cart.











Everything needs a center, so the stock tube compliment that ships with the amplifier is carefully tested and voiced for the amplifier. They are of the highest quality and ideal for those who wish to not worry about tubes and just enjoy the music.



TUBE ROLLING (SKIP THIS PART IF YOU'RE NOT INTO CHANGING THE SOUND OF YOUR AMP)

If you decide to change the way this amp sounds despite the fact that we ship it with hand picked top quality tubes that we like, that's ok. The truth is that a great single ended amp is the amp you can't hear leaving you the rather empowering opportunity to experience the unique and delicate signatures of a large variety of tubes. In other words, it becomes an experience of listening to the tubes and about the tubes... not the amplifier.
 
To that effect...


All of these tubes will work in a Mini Torii - each pair sound different.

GET THE POINT

There are huge sonic differences between the 6V6, 6Y6, 6K6, 6F6 and 6L6 output tubes in the Mini Torii II amplifier. The differences are not unlike owning a completely different amplifier with every change.

All are compatible with the Mini Torii. These are just the output tubes, of which the amplifier uses only two, one for each channel. The above list is only a sample of some of the really good sounding N.O.S. tubes you can enjoy in this amplifier. Of course there are also lots of the standard 6V6 tubes that the amp was specifically voiced for that also sound great.

VOLTAGE REGULATION TUBES

your amp will ship with an OA3 Voltage Regulator tube for each channel. This is the best performance of the four.  The remaining three (OB3,OC3,OD3) can be used to take the tube rolling experience to a deeper level. The four voltage regulator tubes above all modify the operating points of the output tubes they supply high voltage to. This in turn changes the way the output tube sounds.



CABLES

This amplifier is so transparent that differences between cables will now become big differences. If you don't have good interconnects or speaker cables or just not sure how good yours are... we offer reference quality cables that will let you hear its full potential.

SUPPORT

This amplifier is hand built in the USA by DECWARE / High Fidelity Engineering C0. It comes with a lifetime warranty to the original owner. If you purchase one second hand and ever have questions or technical problems we WILL be happy to check it out for you and service it if needed for a very reasonable rate.

We also have a support forum with many people who own this amplifier who's experiences you may benefit from. 


REVIEWS

You may read reviews on our amps going back 15 years. Since this amp is new, the best place to find reviews on it will be in our support forums.




HISTORY of REVISIONS / OWNER'S MANUALS


Mini Torii amplifier

MINITORII - 2009 to Oct 2012


Easily distinguished by the gloss white chassis plate.  Original models used a 7 pin 6X4 rectifier tube that was later changed to a 9 pin current production EZ90 rectifier tube.  Owner's manual below:

Minitoriimanual.pdf
Mini Torii II

MINITORII-II - New in Oct 2012


Also easy to recognize because the finish has been upgraded to black wrinkle.  Features user adjustable variable feedback.  Cryo treated beeswax signal caps are now used throughout.  New high mass Steel Chassis for improved micro-phonics... ads 150% more mass!





MINITORII-III - New in Oct 2015

Installed UFO output transformers for nearly 400% wider bandwidth and an impedance switch that lets you hear your speakers on both a hi and low impedance settings.  An ultra serious upgrade to an already incredible amp.




This amplifier requires no adjustments or maintenance other than changing tubes every couple years. It is a self biasing design and dual mono - meaning tube matching is not required.
