Last spring I demo'ed a used Polyfusion 960 for a couple of weeks in my home. At the time I owned a BAT vk-500 and liked the Polyf better. It had a sweeter more pristine sound than the BAT. Only problem was that with my Aerial 10T's it ran out of steam rather quickly and would begin to compress. In comparison, the BAT seemed to have an endless supply of energy. Used at $1500, it was a pretty good bargain, but I passed on it. Shortly after that, I bought a used Moon W-5 and then finally a used McCormack DNA-2 LAE amp.
The polyfusion certainly appears to be better sonically than some to many of the more popular amps.
