The most amazing 2 integrated amps I have ever heard are the Jadis Orchestra Reference, but only about 40 watts - main down-side is that it is a bugger to bias - you have to take it apart - and, even more impressive in many ways, the Bel Canto SETi 40. This is a remarkable sounding single ended int amp, with a digital-logic 0.5 db stepped remote volume control and that pure, involving, unique SET sound. (845 tubes)
But then 40 amps have to be enough. But what incredible 40 watts. Call Matt at Bel Canto - he's a helpful, honest and smart guy and will tell you if it's enough power for your speakers. You'd have to find it used. It's $6K new - used about $3500.
