Anyone have experience with the Datasat RA7300 Amp

I'm running a group of seven Maggie panels LCR (2 x 3.7s each with a DRM plus a tri-center set up). I'm currently using a McIntosh MC2807 - 200 wpc to each of the seven panels. It sounds very good, but I am occassionally lighting up the overdrive lights. I can trade the Mc back for what I paid against a Datasat RA7300, but even then the uptick is substantial.

Anyone have any experience with this amp or other Datasat amps that you can share?

TIA,
gordon
