I'm using a GamuT DI-150 right now and it's the best integrated I've had, period. And I've had a lot! But boy is it expensive!!! One that made the Absolute Sound "Best List" is the Primare I30. Great build quality and beautiful sound. I own it as well. It fits your budget. I had the yba Passion and it was a top notch amp as well. But the "sleeper" amp is the Marantz PM11s1. Fantastic build quality and beautiful sound. Powerfull too! Doubles watts from 8 to 4 ohms(100 to 200). All these amps have lived in my system driving Kharma Referance speakers. If you would like e-mail me with any questions. Peace and Good Listening, Pat.
