Best bang for buck integrated amp for $500


Looking for best bang for buck amp for under $ 500.  I have triangle Bro 2 speakers already and cables and a dac.  So just looking at a amp.  Something in the 50-100 watt range, slightly on warm side of neutral, good low end, all the good stuff.

Right now i own the Emotiva basx A-100 its not bad i paid $199 but i want to step up my game.  Im kinda looking at Cambridge audio AXR100, a couple of yamahas, but wide open to suggestions ?

I owned the Rega Brio R.

1. High noise floor so a poor choice for a desk unless you don't mind tweeter hiss when nothing is playing.

2.  Upper mids/lower treble are a bit boosted...giving it a fun and lively sound (toes tapping). Tone/timbre is very good. 

3. Treble is a bit coarse and unrefined, even for a $1000 amp.

4. A great value at UK prices...600 pounds 
Rega Brio. I have been using the latest version ever since it came out with my ProAc Tablette 10 Signature in my second system. Never had the urge to try something else.
Creek 4330R is a great budget integrated for under $500. Same with Audio Refinement Complete integrated.
