Henry, I had a similar dilema not long ago. My wife buys mostly new, well recorded CDs. I buy mostly 70s, poorly recorded CDs. And we have alot of average sounding CDs as well. The new stuff sounded bright, the average stuff was listenable and the old stuff sounded like Charlie Brown's mother speaking over the telephone. I called my audio advisor and explained the problem and his immediate response was,"you need better speaker cables". I thought that was completely counter intuitive but since he never steared me wrong before, I auditioned about seven different pairs. In the end, he was right. EVERYTHING now sounds better than before. Replacing the power cord later brought marked improvements but not as great as the speaker cables. Matt........
