13th Note HiFi Review of Network Streamers

@agillis Since the UltraDigital comes after the OpticalRendu. Along with the fact that it must have a power supply then the benefits of the OpticalRendu would be lessened. The Power Supply of the UltraDigital would be inside the isolation barrier that the OpticalRendu provides.

Lumin u1 , and u1 mini  priced $4 k, and $2 k
andhave great interface for library organization  similar to Roon
If you don’t need all the footnotes for each song or album.

The u1 is $6k my friend bought used at $4k it sounds great  the U1 mini is a great buy ,and add a S booster linear PS it’s better still for $450 
Mike at audio Archon installs them and backs them as part of the mfg warranty .
