Doshi Audio – V3.0 Monoblock (pair)
What does performance mean to you? Is it simply a matter of sound quality, or is there more? At Doshi Audio,
performance begins with sonic perfection but must also extend to ease of use, visual beauty, longevity,
and the ability to flourish in the widest possible variety of systems.
After more than a decade of relentless refinement, the Doshi Monoblock has reached a level of audio excellence that,
in our opinion, is unsurpassed. Taking full advantage of the impressive new KT150 Output Tube has enabled an increase in power but,
more importantly, it has empowered us to fully implement the Doshi Design Philosophy,
which entails using the simplest possible circuits in order to amplify the delicate audio signal without degradation.
To create the most advanced circuitry available today, Doshi reached back to the „Golden Age“ of Tube Electronics
and developed a thoroughly modern implementation of a classical tube circuit; namely, the Pentode Output.
This topology enables Doshi to generate massive power with an absolute minimum of active gain stages.
Our V 3.0 delivers over 200 watts per channel but that specification can’t begin to convey the musical majesty that awaits Doshi owners.
Connected to capable loudspeakers and fed a high quality signal, our Monoblocks deliver a level of detail,
dynamics and pure palpability that, in our opinion, conveys recorded music with greater realism than any other amplifier.
At Doshi, however, Performance begins with sound quality but doesn’t end there.
Equipped with both both Single-ended (RCA) and Balanced (XLR) inputs, Doshi Monoblocks feature a 50kOhm input impedance.
The result? Our amplifiers excel in virtually all systems, regardless of connectivity or electrical characteristics.
Also residing on the back panel, our “Mute” function uses microprocessors to block signal at both input and output,
facilitating cable changes and system maintenance. And since even esoteric stereo systems must now be
„Control Friendly,“ an optically isolated 12 Volt Trigger Loop enables our amplifiers to be turned on and off remotely.
Doshi understands that components must be seen as well as heard; therefore,
we pay considerable attention to create products that are as beautiful to the eye as to the ear.
The chassis of our Monoblock is decptively simple, as our Three Stage Decoupling (TM) technology
virtually eliminates the influence of both external and internal resonances upon our amplifiers‘ performance.
Inside the chassis, critical audio circuits are point-to-point wired and mounted on an acoustically isolated sub-chassis.
The entire chassis is suspended from a ½“ thich slab of DuPont Corian which, in turn,
floats upon four vibration absorbing feet that are mechanically decoupled from the chassis.
While our competitors build their enclosures from mild steel and aluminum,
Doshi uses extremely strong 14 gauge stainless steel to create a chassis that is mechanically and electrically inert;
as a result, our amplifiers exude quality while providing an ideal foundation for performance.
Elegantly simple, our Monoblock’s engraved aluminum front panel announces the quality of the circuitry
within while facilitating output tube biasing and other critical functions.
A variety of Powder Coat or chrome-plated finishes encourage the customer to tailor the amplifier to his/her tastes and room decor:
a potential for personal expression which few of our competitors can equal.
In another design flourish that all Doshi owners will hear—but few will ever see—the insides of our transformer covers
are coated with an advanced sound-deadening paint developed to make nuclear submarines “Invisible!”
The Doshi Monblock is the culmination of decades of reasearch regarding circuit design, product longevity,
resonance control, system compatibility, user-friendliness and aesthetic beauty.
While many fine products excel in one or another aspect of performance,
we believe that Doshi’s ability to deliver a completely satisfying ownership experience is unique .
We hope you’ll agree.
