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 ?

Seriously. Big, big bang! Nothing to lose for that price ($76, really?) , and easily returnable via Amazon if needed. I have a smaller model running a pair of KEF ls50s for a couple of years now and this line is amazing for the price. They also provided good customer service when I had questions early on.
Hey man appreciate all the responses I got to look over all of this.  I see somebody mentioned the Rega IO I kind of like it or the Rega Brio I know it's over my budget but I read nothing but good reviews and things about that amp but I'm going to look over all your guys suggestions today and see.
Wow some great suggestions, i like that music fidelity for 499, heard good things about them.  The Rega IO looks nice like the desktop idea, but 30 watts seem a bit weak.  Now the Rega Brio im really liking at 50 watts, but its $1000, and thats over my budget.
