Hammer,
Changing your system to make great recordings sound OK and poor recording sound OK is possible. It is a compromise that many audiophiles are willing to make in order to enjoy more of there music collection.
I have never had the Krell, B&W's or Rotel in my system, so I'm only going by hearsay. However, I've heard the B&Ws called bright, I've heard Krells called bright and I know the digititis from many CD players is often called bright. You might just have a system that is completely comprised of bright sounding components.
You might consider either adding a more musical or softer CD player, DAC or tube buffer to the system and see if that helps. You could also consider a warm sounding set of cables. These things could be tried for very little money as you could just buy here used and re-sell them if you don't love them.
Personally, I think your speakers might not be the best choice for your setup. If indeed they are bright sounding speakers (as I've often read) and you have hard surfaces in the room and they are close to the wall, they just might not work for all of your musical taste. Mabe a more "musical" or softer sounding speaker would allow you to enjoy more of your collection.
BTW, I once owned a pair of highly regarded monitor speakers that were unlistenable in my room. I have to think it was a matter of room and system synergy that caused them to sound so bad, because they were nearly universally loved by everyone that commented on them. You could have the same scenario.
So, you may want to choose to make your excellent recordings sound merely good and your Horrible recordings sound OK. It's a compromise, but it might be an appropriate one in your case.
