Bob - Yes, OP is "original poster." As for your system, it is excellent, and far better than I was assuming in my previous post. In light of that, I would say that you would certainly hear significant improvements with the Pace Car. Whether it is your best option for getting the most from Sonos is another question. I think it depends on the dac you are considering. Given the amount of jitter inherent in Sonos, if I were you, I would want bulletproof jitter rejection in my dac. Short of that, I would seriously consider a reclocker like the Pace Car.
