I am running a ROON on a Mac to a SONICORE Orbiter SE - and into an Audiolab M-DAC+ via USB asynchronous. The unit supports up to 384khz and DSD 128. I am upsampling from ROON or HQ Player - all of my music library is sourced from TIDAL.
(The M-DAC+ is output to a Marantz pre-amp, 2 Audiolab power amps, Focal 926 speakers).
I have picked up my third M-DAC+ today - the other two developed problems after only 4-6 weeks each in my system. Both were reduced to severe crackling - indicating something failed in them. This was confirmed by the dealer playing a CD source - so the problem was not exclusive to USB. Something has caused the same failing twice.
My question to ROON Support and the Forum is whether there is any evidence/settings/instances/anything at all that could suggest what might be damaging these units before I put a new one in service.
For clarity, since I got ROON 18 months ago, I have used an OPPO-HA2 without any hitches and it is back in the system now without any problems.
All feedback welcome.
