Closing the loop on this. All three of you guys were spot-on; thanks.
Spoke with Rick, shipped him a unit which was modified and back to me within 10 days or so. Very pleasant folks.
I'd been listening to an unmodified unit while Rick did his work. When I received the modified Sonos, I added it to the Dacmagic as a second digital source through an identical coax anticable ic. Switching between the two, playing the same apple lossless files, difference was immediately apparent. Really pretty extraordinary.
I'm sure that it's now broken in and better still, but I can't yet honestly claim to have decent enough persistence of hearing to be able to say so for sure. All I know is it sounds vastly superior to the stock unit, at least in my experience.
