I'm in a two channel system now with a PS Audio BHK Preamp, BHK Monoblocks, and Focal Sopra 3s.
The music is bright and disappointing.
Aside f rom that, I'm thinking of going to a Home Theater system with Focal Sopra 2s, Focal Sopra 1s and a Focal Center speaker.
I have to ask why you’d go right back to Sopras after such a disappointing outcome with them in your stereo system because it probably ain’t gonna get better in a HT setting. There are tons of fantastic speakers at and even below the Sopra’s entry fee, so why the fascination with and devotion to that model? If it’s me and I’m using the term “bright and disappointing” to describe my system, I’m not walking but running in a very different direction. My advice would be to go listen to other speaker/systems that don’t sound “bright and disappointing” and move in that direction before even contemplating what prepro/amp to go with. But that’s me. Best of luck.
