I use a Rotel RB-1590 with 702 s2's that although different than what you are pairing them with I believe similar enough to share my experience. If your speakers are like mine they love the juice, the more they get the better they sound in every way, I don't find the pairing in anyway problematic, quite the opposite. For the money I have invested the return has been spectacular. Good Luck with your search, the RA-1592, as well as the RMB-1585 I would think would be great choices for your system, the benefit of the RMB are the cooling fans and newer technology, I also think the Michi S5 would be even better, just my .02, Enjoy ! : )
