Tube DAC to take edge off Rega Planet 2000

You may want to try the tube buffer by musical fidelity runs around 300 or so.

I would like to know how you drew the conclusion that your CD Player is the problem, and not a speaker/room issue.

I've had the Rega Planet, Planet 2000 and now the Jupiter 2000 which I run with a Mac MC275 amp and C2200 preamp. The sound is not at all edgy, nor should your Planet 2000 with the MC2275. I'd check into the cables as a match. The JPS Superconductors are very clear although not edgy either. Actually, I just demoed the JPS cables and should receive my order in a day or two becaues I found them to be a great match with the Mac and Rega equipment.
Perhaps the JPSs are not a good match with your current amp.

Something is amiss but I doubt it's the Rega; unless it has developed problems. Call the Rega distributor to determine if there may be a problem with your 2000. Maybe it needs a service check.

Thank you for the input. I'll look into these options.
