Hello Mapman,
Thanks for responding. I am streaming my own files, and I do not use a streaming service. I have not tried the DAC in the Cambridge, as I sincerely doubt it would perform as well as a DAC costing twice the entire CXN V2. The two changes made are, as I mentioned, moving the files themselves from a PC to a NAS, and switching from the Logitech to the Cambridge streamer.
Since I am still using the same outboard DAC I didn't expect that the Cambridge would insert its own sound into my system (or at least thought it would be minimal, or better!).
Best Regards,
Tom
