It may be time to go the separate route with a Audio Lodic or Chord 64 DAC. I tried a bunch of CDPs Wadia 861B, Audiomeca 2X, extremely modified Shanling, Resolution Audio Opus 21, Accuphasse 77, Sony ES777 and found them all to have various strengths and weaknesses. I prefered the Wadia overall but at the askig price, I found better performance in going with separates. Check out the CEC T1 & T2 transports and the DACs I mention above. That combination bettered the CDPs that I compared it to. Another option is to get a CDP and have it modified, I know a local tech that modified the old Pioneer DP-65 and it is killer for about $1500.
Happy Listening.
