A different approach: I am with you, Bigwavedave! I like the music I like and will not be forced into listening only to audiophile-approved records. Plus, while some remasterings are indeed great, who can afford $40 to $60 for an LP or remastered CD? Here is one idea: When I upgraded my speakers from my Vandersteen 1C to Ohm Walsh 2000s, I got something I did not expect. While good recordings do indeed sound wonderful, the bad ones have become much, much more listenable. Numerous times, CDs that I had thought were unlistenable have become enjoyable over my new Ohms. I have often thought, "oh, so this was what the engineer was hearing in the control room. Not great, but okay."
Why the change? I dunno. I am guessing that inexpensive crossovers at exactly the frequencies to which many are most sensitive, 2.5-5kHz, add to the badness of bad recordings. My Ohms run full range up to 8kHz (I have subs that come in under 80Hz as well). So, without a crossover to mess up the sound in that crucial range, the bad recordings are only as bad as they originally were, and the edginess is not increased by the loudspeaker. This, of course, does nothing to restore the flattened dynamics that you complained about, but at least I can enjoy these recordings again.
Try some speakers without crossovers, or no crossovers in that upper-mid to lower-treble range, like Ohms, Martin Logans, etc., and see if those horrible recordings are a bit more tolerable.
