Benefits of Bi-Amping high-powered amps?

Obviously you don't have a power problem issue, but bi-amping can provide other benefits. The advantage of using an electronic crossover, and eliminating the passive ones, can have a real sonic benefit. Also, vertical bi-amping provides true dual-mono amp configuration, which can also be advantageous. There are also some trade-offs like cost, additional interconnects, system complexity, longer signal path with the elec. Xover, etc.

There is a place in philidelphia called DAVID MANN AUDIO.
I had some good conversations with Barry Mann about this and he seemed real intellegent. Then I did a search on the web and found he actually had a white paper on the subject, and from my conversations with him, I could also tell you that it is his experience, not (just) theory. In short, the long version of the above, (HA!).

I am guessing that the improvement would be marginal and have a bad price/performance ratio. I probably would get more bang for my buck buying a Hydra or an Audio Magic Stealth and some Aurios.
Of course, the best place to spend the 2-2.5K might be to get a record washer and an analoge set-up. I'm sure Twl would agree.
