Source, source, source! I adamantly echo the above comments. The Adcom is the likely "weak link" in the system. Audition higher quality CD sources (Wadia, Linn, Naim) and evaluate the change for yourself. And of course the room should ALWAYS be considered a component.
It's not the sound I want!
My system consists of a Krell kav300i, Aeriel Acoustic 6s and AdcomGCD750. I have Cardas cables , Jenalabs interconnects and Synergistic Research ac chords. It sound great at times but I find many cds hard to listen to. I listen to vocals with acoustic guitar and the guitar sounds detailed but so metalic and unnatural. It sounds like sombody is playing a saw with a bow. Is this what digital really sounds like? Is it sytem matching? I dont think it is the speakers. Is it just a matter of settling for the best we can get for $8000.00 and limiting what we listen to?
