Default Conrad-Johnson HD3 USB DAC

Gentlemen - Available now for those such inclined

Conrad-Johnson's new USB-only DAC, the HD USB3. While the digital portion was designed by Kevin Halverson of Muse, Johnson emphasized that their own designers spent quite a bit of time getting the analog part of the DAC just right. He likened the analog circuitry and its importance to final audio quality with the vital function a phono preamp plays in a vinyl playback chain.

I found the listing on Spearit, but can't seem to find anything more about it.
No mention on CJ web site... at least that I can find. ??

Max sampling rate is 24/96.

I think HD3 uses the Tenor TE7022L adaptive receiver chip.

Hi Wizard
I'm curious as to why Eric Halvorson would use an adaptive DAC chip when has used asynchronous DACs in his HRT Music Streamer designs.

I was too fast there - asynch. of course - the designer is Kevin Halverson from HRT.
But the 24/96 sampling rate is correct ( I got it from CJ's Spanish importer)

24/96 is also a curious decision. Why not 192?
