I disagree with joe_coherant. I find the entire Theil line to very much on the fatiguing side. Way to edgy for my tastes in the highs. I would recommend going to a tube amp and/or preamp to tone down the sizzle of the solid state gear. Good luck, I can imagine what you are going through.
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.
