Anyone still using (still available?) an Elac, Discovery? I use mine hardwired to a Mac AirPort Express wirelessly connected to another AirPort that's hardwired to my router. Have a BNC to RCA Coax connection (various better cables) to a Line Magnetic DAC. The result is shocking great. For $1K is a wonderful piece. Comes with a abbreviated version of Roon too with a lifetime subscription. Couldn't be happier with the product and features, actual high performance AND value.
Ted … would a powered USB hub connected to a linear power supply address the USB noise issue?
It will help compared to the typical noisy USB supplies in computers and the wall wart USB hub supplies. You only want the DS on the USB hub with a linear supply and you want to use a shorter USB cable there (6’ or whatever, not 15’.)
