The Rowland amp, which is very stable at lower impedances, should have no problem handling two sets of Accoustats. Just run two sets of speaker cables from the amp to the two sets of speakers.
The Accoustat is a fairly civilized speaker, as it does not tend to go below 3.5 ohms. Some 'stats go down to 2 ohms, which can cause many amps to "fart in your general direction" and shut down on you! Running two pairs off that kind of amp will make them run away from home, never to return...)
