Bridged Spectral DMA 50?

Does anyone have any experience/thoughts on bridging the spectral dma 50?

I use one right now, and I see them out here from time to time and I'm curious about buying another to try the bridging. Any thoughts on what I might expect if I go from 1 to 2 amps? Prior plan had been to go up the ladder, maybe a 180 gen II, a 100S, or 160 used, but this would be alot less $$, and none of the amps up the ladder are available used.

System:
Digital - Krell KAV 300 cd
Vinyl -Project RM5, benz MC20, mcccormack micro phono
Preamp - Spectral DMC 15
Power - Spectral DMA 50
Speakers - Thiel 1.6
Cabling - MIT throughout

Thanks,

Robert
