VTV Amplifier Custom Hypex Input Buffer made for the NEW PURIFI 1ET7040SA.
The VTV Amplifier custom input buffer board’s modular design allows virtually any DIP8 dual discrete or API PRO form factor discrete opamp of your choice to serve as input buffer.
–Designed by Andrew Sparks of Sparkos Labs
–Available high quality discrete Class A opamps in this listing . They provide significant increase in detail and soundstage. It is as if a veil is removed from the sound. Class A warmth with no lack of detail. You can research all of these industry standard opamps on various electronic forums. The gold plated Mill-Max connectors make changing the API opamps very simple and the connections made are very secure.
—The factory gain for the Hypex buffer is 14db…..too high for many systems. This board has a default gain of 7db. You can restore the factory gain by simple jumper.
–Careful selection of resistors and other components ensure the highest fidelity.
–Dimensions 84mm x 89mm
–A buffer is only as good as its power supply. The VTV AMPLIFIER Input Buffer uses the SPARKOS SS78xx and SS79XX Discrete Voltage regulators. This is a no-holds barred regulator found in many high-end brands and a huge improvement to the IC 7815 and 7915 installed by HYPEX. Specs for these discrete regulators:
