NEW Stereo VTV Amplifier with Purifi-Audio 1ET400A modules and VTV Custom Vacuum Tube Buffers

Designed by Andrew Sparks of Sparkos Labs, the VTV Vacuum Tube Buffer features a direct coupled dual triode driving a four transistor Wilson current mirror.  The output of the current mirror feeds an I to V converter stage featuring the Sparkos 3602 dual discrete opamp as standard.   The board is compatible with almost any dual (or two single) opamps.  There are NO capacitors in the signal path.

    Quietest, most effortless amp I’ve ever heard. Quiet in terms of zero distortion, extremely high signal to noise ratio, zero signal alteration. Just pure music. Late at night, during the quietest hours of the 24 hour period, I even held my ear to the speaker with no music playing, and could hear zero hiss. This amp is scary good. It’s a keeper.
    Another reviewer mentioned that it competes with FET amps many times the cost. I would agree. And it always runs cool. FET amps you can toast bread on top even when they are not playing music.
    The cabinet is of exceptional quality and comprises most of the 15 pounds of weight. Two suggestions for improvement 1) the speaker terminals are mounted just above the balanced inputs. If you have extra stiff high quality speaker cable spades, it’s difficult to attach them when the balanced cables are plugged in. With ample real estate on the rear panel why not space them out more. 2) My preamp does not have a 12v trigger output so I did not order that upgrade for this amp. The Teac UD-505 DAC/ Preamp times out and powers down when there is no music signal for a 10 minute stretch. Most modern active speakers behave the same way. Perhaps a timer option should be offered for the VTV line of amplifiers.
