Interesting...
I went the other way. After upgrading to Spendor D9 speakers I found that some recordings sounded a tad bright and cold. Using a Linn DSM with a Pass Labs XP-20 pre and a 250 watt Bryston. Prior to that combo I had Rega gear in the mix. I replaced the Bryston with a Pass Labs XA30.8 which now seems to work much better with this system. Some of that bright shine is gone, I now enjoy playing music for hours without reaching for the volume control...
