Hi RX,
I used bridged DMA90s for awhile and while they sounded good, I didn't think the improvement was worth the price of the second amp. And the noise level really increased in bridged mode. I tried a DMA150 which didn't play quite as loudly, but had a much smoother and musical upper mid and high frequency range. I ultimately ended up with a DMA180 II which was phenomenal.....it had plenty of power yet with wonderful finesse and musicality.....the best of both worlds. At the time, I was using a DMC20 pre and Avalon Arcus speakers. Going up the MIT cable line also produced significant improvements. The biggest changes were going from 350 spectral interconnects to 350ref single ended, and then the ultimate was going to 350 shotgun balanced cables. g
