Has anyone tried the 7075's with the Linkwitz Orions? They should be a good match since Seigfried recomends (and sells) the ATI distribution amp. There are a few differences, obviously 2 boxes with outlaw vs 1 with ATI - this should be a benefit to the outlaw - more flexibility to location and wiring, greater separation electrically and 2 transformers.
The frequency response, THD and IM distortion, damping, crosstalk and gain figures are all identical. The outlaw power band is 5-125k vs the ATI 5-100k, shouldn't cause any audible difference. The slew rate of the outlaw is 50v/microsecond compared to the ATI 30v/microsecond, a theoretical advantage to outlaw - again not likely anything audible. The input impedance on the ATI is listed at 28kohms vs 50kohms for the outlaw. I'm not sure what difference this will have, especially in the case of the Orion speakers where each amp chanel only drives an individual driver. Maybe someone here could comment. At $1835 for 12 channels of ATI 60 watts vs $1400 for 14 channels of outlaw 75 watts it certainly seems that the outlaw is the better bargain. For an even better bargain you could buy 2 B stock units for $1200.
It's odd that the outlaw isn't listed at the Linkwitz site under alternate amplifiers.

I think you reasoning is sound. Have you heard either the Orions or Plutos?

I chased the Orions to the Linkwitz site. There are some folks there that have an incomplete picture of the 7075 and its capability. The 7075 will meet or exceed any need the Orion project places on it. The Outlaw sub are built by ATI and are as well built. There is at least one Orion user that has the twin 7075 setup and is happy with it. Once in a while Outlaw will place the 7075 on sale and then would be agreat time to get all the channels of amplifier you need. By the way the Plutos are very interesting to look at as long as the WAF is not considered.

I agree - the 7075 seems like a perfectly reasonable candidate for this project.

Hi. I read someplace on the Linkwitz site (or related), that they picked the ATI amp in part because they could drive the amp to clipping and not damage the speakers. Can't imagine that the extra 15 wpc would make that big a difference.

Audioboomer - Have you gone forward with the Orions?
