OP,
I have a revealing, musical, thoroughly enjoyable, CD-based system that plainly doesn't have a problem with lesser CD's any more than with the exceptionally well made ones...by all means try some of the suggested solutions out on your system (personally I'd start by looking at some sort of power conditioning)...if that doesn't work, please send all your unwanted CD's to me!
