I have a Krell KAV300i amp, B&W 703 speakers, Rotel RCD971 cd player and a REL Storm sub. I want to upgrade my cd player and later move onto home theater. Please could someone tell me is this Unidisk SC going to better the sound of my Rotel and how well it plays other sources? Is a 4.3kg little box going to play all the format varieties well AND still act as a decent processor? Or shall I rather look at separates instead? Any info on the Unidisk SC from owners will be appreciated.
