I hate to jump on the band wagon...but the Adcom is not the best choice. I would also say that the Krell, in my opinion, is not a very good amp either. Hyped, yes, but it's performance leaves much to be desired. I know that an integrated helps shorten the chain and lessens cost, but how about selling both the Krell and the Adcom and use the funds along with a bit extra(less than adding a DAC to the Adcom), and look for a good quality neutral amplifier and find a used Wadia 830 (former class A component, recently discontinued) and going direct connect, using the variable out of the Wadia for pre-amp functions,if you are a single source person. There are a number of reasonably priced used amps out there by CJ, ARC, Pass, ETC. that would make your promising system really sing!
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?
