If you enjoy your classe, then more power to you. How much is double, $3000? I agree that the kav250 would be a good choice, but for a little bit more, you could look for a used fpb200 or vt100mkII. I was in your exact situation before; you can email me if you want to discuss further.
mono or stereo? (classe or ?)
I have a classe ca-100 ($1500 new) and was wondering if it would be better to buy another one and use them as mono blocks or would my money be better spent on a 2 times more expensive stereo amp (doesn't have to be classe)? My other gear is wadia, thiel, MIT, and a passive preamp. I seriously want to know so any knowlege is appreciated.
