I think an Atma-Sphere OTL amp may get you closer to the SET sound while also providing sufficient power for your speakers provided their impedance doesn't drop below 6 ohms. Even the S-30 might do the job nicely.
If you're interested in this route, I'd recommend contacting Ralph Karsten directly and discussing your speakers with him.
An Audio Note 300B parallel SET amp might also work. They're pretty expensive. You are probably aware Audio Note Kits also has 300B parallel SET amps as for considerably less money.
A solid state alternative would be a First Watt J2 or M2.
