Perhaps I missed it when I read the article, but what receiver or pre/amp did you use to power this setup?

For surround listening I mostly used an Integra DTR-8.8 receiver. For two-channel listening I used a Peachree Audio Nova integrated amp.

I want to duplicate CyberChrist's request for the equipment used in the review. I love the sound of the Motion 40's and was excited when Martin Logan announced the Motion 60xt towers. There have been a review or two so far mentioning the 60xt's would benefit from Room Equalization software which is the reason for my inquiry on the amp used on this review.

Please see my comment above for amplification. As is normal for loudspeaker reviews, I did not use the Integra's Audyssey EQ, as this would mask the precise characteristics we are trying to identify during the review process.
