I know that Maggies are designed with SS, so we can expect (respect) that synergy, but has anyone thought of the Berning ZH270 ($4K retail)? Its a one-box OTL that drove the hell out of some Acoustat 1+1's I heard - apart from Apogee Scintillas, a speaker recognized as a bear to drive, and a 'stat to boot. Also, since tube, you can experiment with different input tubes to your harmonic taste. The Berning has a very loyal following (see the thread going on now) and it is imminently preferable to the Innersound. If I was you, Philojet, I'd A/B the Plinius, Electrocomp. mentioned, and the Berning. After that, I'd run to buy a Supratek Triode Syrah pre ($2200)... and never look back. Good luck.
