The Spectron, which I've not heard offers the best chance of change....for better or worse TBD.
4bsst not enough juice for Maggies? OUCH! at 500x2 into 4ohms, I'd suspect there are other problems....maybe an over damped room? And, Bryston will deliver into all sorts of weird loads. Which the Maggie certainly is not.
I know that Bryston makes some monster Monoblocks which if given there own circuit, each, should 'bout do it.
