I had good results driving a pair of Acoustat 3 medallian mods with a Conrad Johnson MV75A-1---75 watts-6550 tubes.
Where I wasn't so lucky was trying to drive Martin Logan CLS11z with a 75 watt VTL tube amp.
The best sound you will ever get from any of the old Acoustats is to find the old tubed servo amps(nothing like conventional tube amps)and wire them up.
I have several friends who still run 4, 3 Panel Acoustats with the servo amps, and one has the Acoustat 2+2.
I have yet to hear any Acoustat sound as good as the servo amp powered versions.
