I am feeding my Cambridge Azur 840C's DAC with a feed from a Sonos Z80. The Cambridge is in turn going to my Classé CP-700 pre-amp.
The Sonos has a volume control (digital) as, of course, does the Classé preamp (analog). I am currently setting my Classé to a fixed level (64 on its display screen) and I use the Sonos volume control to raise or lower volume as need be.
My question is this: what is the best mix of volume I should be using? Digital vs. analog? I have seen it stated that the digital volume should be set to maximum (0 dB?) and the analog become the only volume control. I've seen it stated that digital volume controls add noise, if poorly designed, as they increase the volume, therefore it sounds like I should minimize digital volume.
Any ideas / suggestions are appreciated.
Thanks in advance, Dave Boyd
