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 ?

Brio is Class AB vs Sprout Class D. I would bet on the Brio for that reason alone. I have heard the Brio a few years back in Memphis and was very impressed b the sound for the money. If I was in the market for a mid level integrated it would be one of the top 3. 
IMHO the Rega IO is a much better sounding amp than the Brio. It punches way above its price point. You should touch base with JohnnyR at the Audio Connection
Would highly recommend the Music Hall 15.3a.  Here's a review of it: https://www.soundstagehifi.com/index.php/system-one/1530-high-value-surprise-the-music-hall-a15-3-in...  

It's a fantastic integrated - I had it in a simple system, but I tried it out in my main system.  I was amazed by the sound quality - clear, fluid, with a touch of warmth.  It's $549 new, so not much over your budget, and they do come up used, so keep an eye out.  I liked it better than the Rega Brio.
Aren't the io and the Brio the same amp just less power is there that much sound difference? I'll have to take a look into that.
