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 ?
