Benchmark HDR vs Audible Illusion M3a

I am contemplating selling my 3A and buying a Benchmark HDR. It would upgrade my DA and consolidate a number of boxes. I could sell my stand alone DA and headphone amp and be gone with three boxes. I don't want to lose sound quality, though.

I am currently using Rogue M120's into Maggie 3a's, with excellent results.

Advice and thoughts are welcomed!!!!!!!!
