My current disc spinner is a Cambridge Audio 751BD which I’m now mostly (except for SACDs) using as a transport, as I vastly prefer the sound of my Bryston BDA1 DAC to what comes through the CA. Even through the Bryston DAC, CDs can sound shrill. The CA works extremely well for DVDs, Blu-ray discs and SACDs, but I don’t think I’m enjoying my rather extensive CD collection as I should.... The rest of the system: ... Hegel H200 integrated.... Nordost coax.
So it sounds like you have the analog outputs of the player connected to the integrated amp, and the coaxial S/PDIF output of the player connected to the DAC, with the analog outputs of the DAC connected to the integrated amp.
I’m thinking that a simple experiment that may be worth trying would be listening to CDs with the analog outputs of the 751BD disconnected. I’m envisioning the possibility that having both digital and analog connections between the player and other components in the system might be conducive to ground loop effects that would cause or contribute to jitter in the DAC. And in fact I can recall a thread here a few years ago in which the sonic issues that were being addressed turned out to be the result of having multiple connections between components.
If that reduces the problem to a satisfactory degree, we can discuss further how to implement a permanent solution.
Also, I’ll second the earlier suggestions that it may be worthwhile trying a different length and type of digital cable, even a much less expensive one.
Good luck. Regards,
