The Brio has been very impressive - it just pulls you in to the music. After a few days powered up it smoothed out quite a bit, and I have absolutely no complaints. The highs are very natural and non-fatiguing, which is something that is difficult to find at this price level. Midrange has nice weight to instruments. As my speakers are stand mounts, I can't say how it does really deep bass. However, the bass that I get from my speakers is very full without being boomy. The overall sound is very cohesive.
The phono stage is much like the amp itself - relaxed, musical, engaging. One thing I wasn't expecting was the quality of the headphone amp. I don't listen to headphones too much, but I might start. It's very dynamic and clear with my Sennheiser 600s.
For $1000 I can't think of anything that compares. You could have an awfully engaging all-Rega system with a RP3, Brio, and RX1 speakers for about 3k.
Anyway, I was reluctant to try it because of the complaints of hum issues, but mine is silent and makes great music.
Best, Scott
