I’ve also put the 555DR on the CDX2. Surprisingly the nDAC without the 555DR sounds very good. I have wondered whether having the nDAC floating relying on system earth via the CDX2 coax (Chord Clearway BNC to BNC) is a good idea. Now the 555 is on CDX2 (no mains) the IC carries the earth which must originate from the 555.
Right now the CDX2 sounds really good. It had got a bit flat maybe with the Rega TT on the dedicated supply.
My dilemma now is that I like Roon and I’m not sure whether to use just a Zen Mini without the LPS with a view to going into streaming eventually. I also have to decide whether in the short term to put the 555 back on the nDAC. I don’t want spend more than needed on a Zen (Mini, Mini+LPS, Zen or Zenith). The noise on the uPnP should reduce on the dedicated streamer port (like the Melco), but no idea how much it matters.
The dealer is going to clean the lens on the CDX2 which has one CD with a bad final track which the Zen did rip. I think I hear more clicks at times also. @Richard.Dane is it ok for the dealer to do this? It has had 3 years of heavy use.
