Opinions?
Mister, you ask a lot. I suggest that you start right away to build something!

You have one real limitation and that is the max supply voltage. +- 42 volts isn't particulary much. But if you have 0.5 ohms load you can get some LM3886 and get real much power out.

I am thinking in using OPA541s for a subwoofer amp. With the National datasheet and using the LM3886 as model, it says we can squeeze 150w from 2 parallel chips into 4 ohms.
