You need to somehow figure out what caused the listening fatigue. Since you don't have your old system, I think the best place to start would be to go out and start listening to some new equipment. You'll need to do that anyway.
System Direction? Thiel 7.2s, Krell, Kimber, SCD-1
Looking for some advice on where to take my system. Started with a set of thiel 6's and a krell fpb 350mcx. Moved up to a set of Thiel 7.2s, upgraded to 450mcx monoblocks with a krell KCT, Kimber ks3038 speaker cables, bmi whale power cables and a heavily modified sony SCD-1. System was setup in a large room - about 40*16. Sound was extremely good - enjoyed the system a lot , but I had some listening fatigue and I would say bass and highs were better than mids. I moved to London for 3 years, sold monoblocks, power cords and KCT. Just back. Still have thiel 7.2s. Trying to figure out if I build a system around 7.2s, and if so with what? If not with 7.2s, where to? I like singer songwriter, female/male vocalists, modern country the most ,but also most music other than heavy metal, rap. I like to listen to music fairly load. Thx for advice.
