Spectral DMC-90's as Mono Amps?

Anyone here have experience running a Spectral DMC-90, "bridged" (i.e., as a mono amp)? Can you describe the experience?

I own a DMA-90 (which I purchased new, ca. 1995) with which I continue to be extremely satisfied. I am in the hunt (still!) for speakers, and several models of speaker at the top of my list probably demand more horsepower than my single DMA-90 can muster. It occurred to me that, rather than purchase a new higher-horsepower amp (and sell my DMA-90), I could purchase a second DMA-90, same approximate vintage as my own, and run each DMA-90 "bridged", one DMA-90 per stereo speaker. (What do you think of this idea?)

Thanks in advance.

I no longer have them but I was very happy with a pair of 90's bridged.
I also had a DMC-12 pre and all MIT cables.
I sold them and tried Class 'D' for a while.
Some time I wish I had kept the Spectral. I do believe you will see an improvement with two 90's bridged over a single.

Thanks, Tan. A long time ago I remember seeing a system which had Wilson speakers powered this same way. I don't remember whether I liked the sound or not, though.

I would not do that. You will compromise the sound of the amp.

Razmika,

Can you elaborate? The amp has a specific switch on the back panel intended just for this purpose. You've actually listened to music played through such a system, and it sounds compromised?
