A center speaker is for home theater, not exclusively music. Two good speakers will give you the proper center channel.
Best CDs
I'm new to Audiogon, and know the depth and bredth 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, Kress 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.
