There are lots of great speakers up to the $5K mark that could go well with the Rogues. I used to own the M150s and they were fantastic amps that did not sound like your typical tube amps.
I own the Harbeth P3ESR and Spendor SA1. Both worthy small speakers that would cost far less than $5KUS. Harbeths have very natural timbre to their sound and sound great with music with real instruments. If fast bass heavy, electronic music is your thing the Harbeths won't suit. Whereas the Spendors have a different sound and I feel can play more genres than the Harbeths as they are faster. They to my ears sound a little more closed in and the tweeter rolled off. What this does believe it or not is really draw you into the music. The sort of speaker that lets you forget about all your gear. Both cracking speakers which is why they are still with me. There is something refreshing with small sealed box speakers that has me hooked!
Just my two cents...
