Theil/Classe 6, and listener fatigue


I have Theil 2.2 speakers, a Rotel 855 CD player, a B&K 442 amp, and recently replaced a B&K pro 5 with a classe 6 (a later model than the DR). There is much more detail to be sure but it comes at the expense of fatigue. The highs are either too bright or edgy. Any advice would be greatly appreciated.

since you have bought classe already there is no alternative but to use interconnect to fine tune the sound. use cardas or audioquest copper cables!
I owned Thiels for over ten years and found them to be amongst the least fatiguing speakers around. I believe this is a function of sheer accuracy. They are detailed and therefore some people who seldom listen to live music call them "bright". I suggest you try a different CD player first.
You may also want to try and change the angle of your speakers. If they are toed in, try moving them to aim more straight ahead.
Kadlec, You didn't mention any acoustic room treatments...if you have a lively room, you might want to treat the 4 upper corners, the side walls the center of the front wall, and the center of the back wall with some acoustic treatments. You can make these yourself from 2" foam and cover them with any cloth that works with your decor. Use hot glue and Velcro to stick them up. (Look at Michael Green Room Tunes for placement and sizes.) Then you can play with speaker cables and interconnects. I'm not fond of the B&K amps, they tend to be boring, 2-dimensional, and lifeless. I've heard the Theils MCS1's with Classe cd, amp and preamp and also thought they were a little too bright. But try the room treatments first, then the cables, and then you can start swapping amps or cd players.
