Headphones and the Devialet

[jvoki]

I think the only reason to use Devialet's preamp headphone output is listening to the phono input.

 I've tried all the way to developing a headphone output and my final solution is Roon on NUC and Hugo2 headphone amplifier directly connected via usb with RAAT protocol and Devialet via digital out to Hugo2 to listen to TT.

  Roon recognizes the headphone amplifiers according to their certification on the roon website.  If your amplifier is not certified, roon will use driver or protocol.  The advantage of roon is the use of DSP functionality for your type of headphones.
