To OP: are you thinking to get another pair of Salk speakers?
If it is Silk (84 db sensitivity), then you want 600R or Synergy 450. If it is SS8 (87 db?), then 400R or any Synergy line would be just fine, imo. There is a 400R on the trading board, btw.
I own T8+ and an older AVA solid state, and really like how my songtowers sound. I think T8 is a must-have if your amp is solid state. At Axpona I heard Fet Valve preamp/600R amp combo and I had a feeling that the electronics does not have a sound. Just dynamic and effortless music, full of details and nuances
