I've got an Audiolab 8000S and a Rega Apollo. I kind of disagree with those who say the Audiolab is bright. When I replaced my Exposure 2010s2 with the Audiolab it really tamed the highs (as well as added a more full bodied and big scale sound, which is what I was after most). I think the Audiolab is pretty dead neutral. The Apollo is widely regarded as being on the warm side.
Unfortunately I didn't get to use my Apollo much. The same day I bought it it malfunctioned. So it's currently in the shop getting repaired. But while it was playing for that brief time I was thoroughly impressed at how well it got along with the Audiolab. I lost a little pace when I replaced my Exposure gear with the Audiolab, but I think the Apollo really injected some of that musicality back. So I would suggest to not rush into a change...hopefully you can do some comparisons in your own home and think this through before committing to anything. I've done changes quickly before and tended to make mistakes that way.
I agree with those who say the speakers might be the offending party. B&W is known for elevated lows and highs. I currently have Quad 12L2 speakers and they are known for being really easy to listen to. And they are. Even the brightest highs on my system don't become shrill and ringing. So if you can try Quad that might help. Or perhaps Dynaudio, also known for being warm and natural.
I'd also suggest some copper cabling. Atlas or Cardas is what I use. Silver is known to be brighter sounding than copper. I think I've put together a system where each piece is neutral but leans to the warm side, and I find it really helps when playing CDs, which itself tends to be a bit of a bright sounding medium. So it kind of balances out.
