Not much doesn't sound great on Proac's, especially with ARC driving them. If you're looking for CDP what's your budget? If you're ok buying used, an ARC CD3 is a nice player. I once owned a CD2 and it sounded nice on Proacs. I've dragged my Cambridge 851C over to my fathers system; ARC with Proacs and sounds great to me. Guessing you don't have your ARC yet. Think you'll be very happy with the combo. Congrats!
