I had a similar "brightness" problem in my system last year.At the time I had an HK 520 reciever,NAD 512 xd,and Mordaunt-Short MS908 speakers.On some CD's it was almost painfull.I tried various combinations of CD players, interconnects,speaker wires ,nothing really helped.getting kind of desperate,I tried a Rotel 1055 reciever for a weekend from a local shop.WOW...finally, CD's were listenable again,I figure the pre-amp section in the Rotel was just a lot better.After I got the Rotel,I rethought my whole setup,and ended up replaceing everything but the Mordaunt-Shorts.It is now pretty much all Rotel,and very listenable.My next project in room treatments
