George, I have (almost) the identical system to yours--EMC I CD, Merlins', and Berning 270's, although I have two running as monoblocks. I tried Quattro FIl IC's--no go, too bright, IMO. Haven't tried SPM's, although some would say there is a Nordost 'house sound'. Using HMS Gran FInale IC's, now, much better. Will (Tubegroover) would probably say my speaker cables (stage3's) are still a little too bright :)( Hey Will, check your email).
Sorry to get off topic. However, the biggest improvement came when I moved my speakers, so I would support suggestions to that effect above. Also, as Khokugo asks, what was your previous amp? And do you have any of the mods on the Berning (ERS, etc.)? The Berning's reputation is for utter neutrality, not brightness. If you are comparing it to a traditional tube amp, it won't sound like that.
