You should get different amps the 6300 should have been swapped for the 7000 and the "baby Krell" should be sent packing and get yourself a real Krell. The Epitome was the non plateau biased early models that knew what Class A meant. They hold nothing back the KSA 250 for example is worth buying and sending it to Krell for a good refurb.
Any Cd player will be much better with those amps. Perhaps the best CDP is a computer transport and server, they are so clean they just cant function if there is a bad clock and jitter is non existant. You will need a good DAC and interface but don't fret computers don't have balanced outputs and stand alone CDPs are dissapearing fast. The other option to consider is a universal player with a good uadio section.
