Amplifier suggestions please

You do realize that cabling is available which has both the XLR on one end and RCA on the other, which does in fact exhibit the same benefits as the "XLR only ", cabling right?

While cabling does exist with this configuration, this really isn't the right way to do it.  Converting XLR to RCA and vice-versa really needs a signal transformer (such as those available from Jensen) or a conversion circuit with an op amp (not optimal at all). 

XLR circuits that don't have a receiving end for the negative polarity can sometimes run hot or not optimum if it doesn't have a "load" on that signal pin.

I'm not saying this configuration won't work, but it is generally not recommended.

And another note.  Trying to turn the opinion of the OP because you have stuff to sell is not completely un-biased.

Well, I never claimed to be, "Unbiased", Hee hee. 
No-one truly can be!
 But you cannot tell me that a, "Threshold", "T-100", amp wouldn't be a nice fit!
 ANY Threshold amp would be really...."IMHO", I've yet to run into one that was not nice.
 And mentioning the other amps was way more to make the point I was trying to instill. I really don't think I'll part with those others right now. But my collection is too large.
 I offer when I think I can really help. Other than that I have never sold anything here. I have never advertised here either. I use other sites for that when needed. Well, For a "charity case" once. But that is it. 
AND I am not affiliated with any company which sells, services or makes amplifiers. "Speakers"? Yes, But not those other components!
 I notice all the time people whom "Are" affiliated with that type of business trying to sell. Usually not, "Outright", maybe but at times that as well. But it's sometimes some pretty, "BAD" advice they throw out.
 "Specifically", when they list the gear which they sell or make.  And many times listing gear that's not really of a "really good" quality or at least,  "No better" than what a person has already! Just a bit more on the, "New" side. And when one is attempting to upgrade a system? AND on a budget? 
That should truly be a "Cardinal Sin"!
   Isn't there a special "10th Circle of Hell", just for that particular transgression??

So yeah, I was in that missive about as un-biased as anyone ever is. 
 It was simply honest.

The only thing Op is going to get at the price range is class D trash. You're only option outside of Aliexpress for a quality amp is to find a used Odyssey monoblock pair. I actually have a Yggdrasil and an Odyssey Stratos stereo amp. My Freya balanced output is just BARELY able to drive the Stratos' inputs due to the weakness of Odyssey amps, their low input impedance. This is probably why it never sounded good, but it could also because my Freya is messed up. Anyway. No matter how unimpressive the Schiit power amps are they're going to be automatically better than the class D junk people will push on you.
