Selling my Audiophilleo 1 (mk1) with Geistnote BNC-coax Apogee cable included. This is an ultra-low jitter USB audio interface for your computer. It provides an extremely low jitter SPDIF signal to the coax-input of your DAC. Jitter from this unit is insanely low, on the order of 2.6ps RMS (10Hz-100khz). This is the Audiophilleo1 (with the full color digital screen), mk1, with 12V trigger option (no 12V supply included), without pure power. The other nice feature it has is a unique bitperfect test feature - it can confirm that you're the bitstream it outputs to coax is identical to the original signal (i.e. Windows isn't resampling or otherwise changing the original bits).

In other words, the Audiophilleo lets you output an absolutely bitperfect signal with extremely low amounts of jitter from a standard USB connection on your computer, into the coax digital input of your DAC. Amazing!

I purchased this unit direct from Audiophilleo. MSRP $974.

It is in excellent condition cosmetically, with minor signs of use.
