Best CDs


I'm new to Audiogon, and know the depth and breadth of the knowledge and experience of the people who post on the Forum, so I apologize for this amateur question.  I'm strictly digital.  I've just upgraded my system with an OPPO 205, Krell Theater 7WD, Krell Foundation 4K, and B & W 804s, 805s, and center speaker.  I've played some CDs (old collection), and they sound awful.  Is there a good brand or brands of CD and/or source that I can rely on for future purchases, or is it more complicated than that.

Oppo only sounds good for 2 channel CD from the XLR stereo audio outputs...
Daj2832, you've gotten some good input so far but give us a little more to work with.  For example:
  1. When you say "awful" what do you mean? Bright? Muffled? Make your ears bleed? :)
  2. Is all of this equipment new?  If so, how new and what are you upgrading from?
  3. Did CDs sound good to you with your old system?
  4. Describe your room to us. Size, shape, furnishings, type of floor, is it full of windows?
  5. What kind of cables are you using?
I'm not familiar with your equipment (but somebody here is). System synergy plays a role as does what you are used to hearing.  A good test would be to find a known good sounding CD in a music genre you like and see if it sounds good to you.  If not, the problem is likely system or room related.
Good cd on good player should not sound "awful", something is definitely wrong. Unless you have zero tolerance for digital, then nothing will help.
CEC belt drive players definitely do not sound awful, even 20 years old. I rarely play cds, though.
