Thanks for the input Rgd. Initially, I was very excited about the immediate and obvious audible improvement to the overall sound of my system once my new amp and speakers were in place and had no intention of looking to upgrade my source. However, now that things have setteled in a bit and I've become used to what I'm hearing, it now sounds somewhat dull and lifeless, somewhat flat, lacking air, grip and resolution. I first thought of the Bryston DACs you mention until I spoke with Dave at Audio Doctor who happens to be a Bryston dealer and said that he could not recommend the Bryston products when there is much better to be had, particularly with the Chord QuteHD. Based on my system describtion, he also felt that my BCD-1 was the weak link as that techonolgy is a bit long in the tooth and did not feel that upgrading to a more advnced one box player would get me the resukts I was looking for and that a DAC was the way to go. YOur thoughts? Thanks again, Jay
