Levinson 23.5 and Biamping Gurus?

I am so far very happy using my 23.5 with newly restored Magneplanar Tympani IV'as.

The system sounds great and the amp seems to have reserves of power to where I can barely crack the volume -- even in a pretty big, very high ceilinged room.

Nonetheless, the more I read about the much smaller Maggies slurping monstrous amounts of current, I wonder if I might be missing something.

Could anyone advise me on adding a second 23.5 and bridging them? That would obviously add gigantic amounts of power and I am wondering if this would take the Maggies to new heights.

To really get fancy, maybe 23.5's bridged and Audio Research tubes on the mids/treble?

It is always fun to buy more gear but I would greatly appreciate any insight anyone might have.

Thank you.
