Pristine condition Doshi V3.0 Linestage preamp original owner purchased
from authorized dealer. Fully balanced, all point to point wiring and
optimized for audio with 3 XLR inputs + 1 RCA input and 1 each XLR &
RCA outputs. Comes with 2x JJ ECC99 Gold tubes Nick's favorite for this
preamp. Alternate tubes that can be used include 12BH7A & 13D6.
Doshi has amazing service although I have never had the need to use it I
can tell because of Nick's quick responses to any questions I have had.
Never ANY issues with this dependable preamp. Built like a tank with
highest grade parts. This is the bomb and by far the best preamp I have
ever heard and I have heard more than my share being a preamp junkie.
Never thought I would part with this piece. Only reason for sale is I
purchased a DCS Rossini DAC with volume control and this pre has been
sitting on the sidelines. It's too good a piece to not be enjoyed by
someone who needs a true reference preamp. Payment via wire, bank check
after clears or Paypal F&F otherwise buyer responsible for PP fee.
Stock remote control included controls volume, input and dims/blacks-out
LED. Check my feedback & buy with confidence.

From the Doshi Website:

Doshi Line Preamplifier takes its inspiration from sophisticated
techniques developed for the recording industry. Based upon legendary
studio hardware including Pultec EQs and Universal Audio Compressors,
Doshi has developed a transformer-coupled volume control, a technology
which offers performance advantages not possible with any other design.
Offering both a fully differential signal path and Galvanic Isolation,
the Doshi Volume Control handles all inputs—XLR or RCA—as fully balanced
and provides isolated, floating outputs, thereby eliminating the
possibility of ground loops at either input or output, assuring absolute
freedom from ground noise: an especially important consideration with
digital sources.

Doshi’s Purist Pathway™ doctrine of circuit
simplicity reaches its full potential in our Line Preamplifier due to
its single gain stage, which employs one ECC99 Dual-Triode Vacuum Tube
per channel: the first triode provides gain while the second—a
“Follower”—minimizes output impedance. Thanks to our elegant circuit
design, the Doshi Line Preamplifier offers zero negative feedback, low
output impedance and the ability to drive any cable and amplifier load.

its sculpted aluminum faceplate, the chassis of our Line Preamplifier
incorporates Doshi’s Three Stage Decoupling™ technology to virtually
eliminate the influence of both external and internal resonances upon
our circuits’ performance. Critical audio circuits are point-to-point
wired and mounted on an acoustically isolated sub-chassis. The entire
sub-chassis is suspended from a ½“ thick slab of laser-cut, 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 components provide an ideal
foundation for performance.

As befits a state-of-the-art
component, the Doshi Line Preamplifier includes an oversized power
supply housed in a separate, resonance-controlled chassis. Connected to
the Preamplifier via a custom-made, heavily damped and shielded cable,
our power supply includes a purpose-built transformer. Manufactured by
Toroid, this transformer is massively over-specified to prevent
resonances that occur when a transformer is run at full capacity. Power
Supply capacitance in excess of 1,500 microfarads is more typical of
power amplifiers than preamplifiers. High speed, low noise rectifiers
and three levels of resistive-capacitive power filtering provide total
isolation of the high voltage supply from the mains, eliminating current
modulation and delivering battery-like purity and stability while
avoiding the high source impedance of a battery supply. In order to
extend tube life, all Doshi power supplies feature soft-start circuitry.

Doshi Line Preamplifier represents the highest level of audio
performance ever achieved in a linestage. The realization of timeless
circuit designs, executed with the finest component parts,
uncompromising build quality and inspiring aesthetic beauty, the Doshi
Line Preamplifier represents a lifetime investment in musical pleasure.
