Doshi Audio V3.0 Line Stage [Expired]


no longer for sale

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. Built like a tank with highest grade parts. This is the bomb and by far the best preamp I have ever heard. 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 fee. Stock remote control included controls volume, input and dims/blacks-out LED. Check my feedback & buy with confidence.

From the Doshi Website:

The 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.

Behind 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.

The 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.
