The OP can change to Klipsch Khorns (104db sensitivity) but then he will have to suffer with their infamous sound colorations.
SET Distortion at higher volumes?
If my SET amp is running out of power with my 96db speakers, does it create distortion that sounds like a record mistracking? I'm trying to track down an issue I'm having at anything over medium levels. I'm getting a high end distortion. Happens at high frequency or energy vocal and horn and piano passages.
