Master/slave link

[Confused]

I have the Audioprana cable, and like many others I am very happy with the sound quality obtained with this cable. When I first had a companion amp as a demo unit, this was supplied by the dealer with a Chord Sarum SPDIF to SPDIF cable. Following delivery of my own companion, I used the standard supplied Crystal cable. I was never fully happy when using this cable, it would be unfair to say the sound was harsh, but the with the Crystal cable the system did not sound as smooth and analogue as I recalled with the demo companion and Sarum. At this time I tried a couple of old SPDIF digital cables that I had (not particularly expensive ones either), and found these to be an improvement. When thinking of a replacement for the Crystal cable, I read good things about the Audioprana and bought one to try. I have been more than happy with it so haven't tried anything else since. Back In the spring I did buy a SPDIF / XLR adaptor, so I could try the XLR link with the old SPDIF cables I have but still using the XLR companion input. The reason I did this was because I was interested in if I could hear any difference vs the Audioprana with it's mini transformer. As others have posted, the Devialet line is that such a transformer is not needed. I have never got around to trying this adaptor, I guess I simply got fed up with messing around with my system due to multiple issues I have had with 8.x.x firmware and SAM 2. (and meanwhile have been enjoying the music) I will give the adaptor a try sometime, it might be interesting.
