Just want to offer my two cents. I have the Modded Sonos and also have an Innuos Zenith MK2. The Sonos probably gives you 75% of what the Innuos does. Where the Zenith separates itself is in the air/space around instruments, as well as the ability to deal with complex music in a better way. If there's a lot going on, the Sonos can get a little compressed sounding in comparison. Now all that said, I have found that adding a better PC makes a difference, as does a better dig coax. The Sonos still has easily one of the best interfaces around for usability, so that is something to consider too.
