If I had your problem I'd simply get a cheap 2d CD player and put a cheap equalizer between it and your receiver and reserve its use for those times you must hear the poorly recorded CD's.
There is no really good way of dumbing down a system so bad CD's will sound good, but I agree that you can improve the sound of a lot of 'bad' CD's if you put the money into a carefully thought out up-grade of your system.
A lot of folks have found that using (some, not all) tube CDP's and tube buffers helps with some CD's which are simply recorded hot and need some taming in the highs. With a buffer or tube CDP/DAC you can also control the tone quite a bit by tube selection.
Just something to think about.
Oh, another cure of sorts - when you are listening to the 'bad' CD's turn down the volume! :-)
