If "tube magic" is what you're somehow after, without wanting to go with tubes, I'm not so sure bi-polar driven amps is the best solution - generally speaking. I'd probably keep the sonic signature as a main priority, and then consider your grounds from here. Mosfet amps is what I'd look into to begin with, and there are likely many candidates which should face no difficulties in driving your Sasha's.
Wanting to simplify ones setup is certainly something I can relate to (as an outset), but in your case I'd be careful no to throw out the baby with the bathwater, so to speak, "just" for the sake of simplicity. Again: I'd hold the sonic signature as a main priority, and then see if there are any integrated solutions that could accommodate your needs.
