+1. Also if the speakers are reputed to be thin and harsh too then together they really will be nasty.I have the Rotel. In my Yammy system it sounds fine.No thinness or brightness. I did used to run an 82 with a 180. In that system most CD players did sound bright, thin and sometimes harsh. It was hard to integrate some auxiliaries. I believe it is your amp set up rather than the CD player. This is how PRAT sounds I’m afraid. Some like it, some don’t. It’s an acquired sound. It was a little too relentless for me but I can understand why some liked it.
The 82 is too ruthless and hard with not enough grace IMO. Had one with Hicap/2 Hicaps/Supercap and it was never satisfactory in hindsight.
I recently sold an Audiolab 8000A and tried it briefly with the Ruarks and it sounded more relaxed and even, but from memory the Audiolab doesn't have the oomph or excitement of the Naims.
