Mid 90's Adcom GCD-700. Dual 20 bit Burr Browns, Class A output section, dual power supplies. Best "carousel" player I have had. It does most everything very well and I am wondering how much there is to be gained by a new unit or DAC. Been looking at the Ayon Tube players and the one I am interested in I can get for $2500. Before I shuck out the bucks for a "all in one", I am wondering if a $500 DAC will do me the same......? Thanks in advance. Oh, the rest of the system is Kenwood 700M/C with homebrew speaks primarily stemmed from JBL drivers. This is a very "dynamic" and revealing system with a front row perspective. My Vinyl rig bests the CD playback in all areas of cource, but I have LOTTS of CD's.
