I certainly appreciate all the comments, but I must not have communicated the issue properly, based on some of the responses. Room correction electronics such as the recommended Antimode Dual Core 2.0, power cords, interconnect cables, or power conditioners would seem to impose their changes to the system all the time, for all recordings. I'm not opposed to general improvements, but good recordings already sound fabulous on my system as is.
What I was looking for were recommendations on tweaking the sound ONLY on those recordings that suffer from the misguided hand of the recording engineer.
An equalizer of some sort that can be switched in or out as needed seems the best recommendation I've heard so far. Granted, use of such a device will reduce transparency, and modifies the sound from what the engineer (or the artist) created. Unfortunately that might have to be the price to pay to make the material listenable (to me at least)'
