Hmm, as I have 24V rails from a SMPS now the question is if I should buy another 24V SMPS so I can get 48V rails and start playing with a R085 mu follower. While I could probably do with one my speaker has high impedance so higher voltage is probably better.

And if I sometime in the future want +- 24V I can reuse the SMPSes but wire differently =)
 
Would it be any problem to wire the SMPSes like this and tap one output at 24V and another at 48?

I want to go active and do a pure single ended amp on the tweeter and a mu follower quasi pushpull on the midrange. Though I have some smaller inductors on the way for the tweeter amps as a 193V is a bit big for that =)
