Agree with Rdavwhitaker's suggestions, and I have found several Totem speakers to be a very good match with MF amps of the A5 generation. A pair of used Devore 8's may also fill the bill. A small floor stander from Naim may also be a good choice. These are not two-ways, but if you can find some PSB Imagine T's used, they are some very nice speakers too.
Finally, These are n ot floor standers, but I thought the Revel M22 stand mounts sounded terrific with the MF A5.
