Marty,
You can still use the Sonos volume when it is connected to an external DAC. I have mine connected to the digital input of a GNSC moded Opus 21 with good results and almost no loss of convenience (the only think you have to do is turn on the Opus 21, but I have to turn on the rest of the equipment anyway, that is bearable, I do it while the Sonos control wakes up!). I also pop in a CD when I want quality, . that is why Im really interested on this Sonos mods, I hope that eventually I could achieve the same sound quality from the Sonos (to a DAC) as I get from my CD player.
BTW, the ZP100 solution is not listenable to me, IMHO it is much better to connect the ZP80 direct to a cheap amplifier (lets say a $500 one used). My ZP100 is used now only to drive my cheap patio speakers.
