Power amp/integrated amp suggestions for SUPER POWER HUNGRY/INEFFICIENT SPEAKERS

Any thoughts on Saga, Schiit’s passive/active preamp? It seems like a good cheap option for something that’s pretty transparent. I'm already creeping toward the high end of my budget, for the speakers, amp, and preamp, so if getting this will give me most of what $1000 would give me, I see no point in spending more.

Wyred 4 sound hits your budget and your wpc requirement.  They are class D.  Could go integrated, monoblocks or dual mono.  I have the dual mono version st500 mk II. I like it a lot.  Runs cool (good for your small room) sounds towards warm side.  The music room on agon usualluly has some used ones available.  I also found some sx1000 (not the “r”) on my local Craigslist for $940.  Happy to help with the transaction if you decide to go that route.  Pm me if you do.  

I got a used McCormack DNA 0.5 for $650 shipped. It arrived yesterday, and while I haven't heard it yet, the build quality and soldering looks top notch. Can't wait to try it out once I get some speaker wire!

Sweet!
