Cavy,
IMO, sounds like a software issue, specifically the poor mastering job performed on some of your cds:
"On some of my cd's they are spectacular, and on others they sound thin on the tonal balance. There appears to be a upper treble glare (brightness)".
That upper treble glare is more noticeable on a better, more transparent speaker.
I'd take one of Steve Hoffman's DCC discs and use that as a reference, or you can try FIM's compilations for confirmation.
Bottom-line, for me, since not all of your cd's are exhibiting this "glare", then it's the individual discs which are the culprit, and not the gear.
Cheers,
TRH
