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 ?

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.  
In the clearance section of Audio Advisor there's a NAD 316 BEE $449.00 40WPC. Bought this for my son as a starter and he loves it.

For a little more power and features there's the NAD C338 50 WPC for $600.00
Try to find a good vintage amplifier they will out perform a new one in that price bracket and for 500 dollars will get you a lot more sound for your money.
