Energy RC-70????

Local guy is pushing these speakers as his favorite brand. Haven't had a demo yet. Also considering Paradigm studio 100s, or some used Martin Logan Aeon i.

What is your opinion on these choices?

Haven't heard the Paradigms either, me neighbor has Logan Aeon i and cinema center and I think it sounds great.

Room is about 13ftx20ft with vaulted ceiling, all chocolate brown dedicated movie room.

It will be used about 95% for moves and 5% music

Also considering using a separate processor and amp to run the speakers
While I have not heard the RC-70's, I would suggest you move up the line and try to find a pair of Veritas 2.3i's. I auditioned last year next to Paradigm Studio 100's and S8's. To my ears, the Energy's were far more resolving and better integrated than the 100's. While the S8's--at more than double the cost-- had the slight edge in treble refinement, they could still not top the expression of the Veritas' dome midrange.
The Energy Reference Connoisseur line offers a completely different presentation of that to B&W's CM series. As you'd come to expect from Energy, the RC-70s are smooth but also extremely rich and detailed. The high frequencies are some of the smoothest I've heard at their given price point. I've read that the RC series is designed with the usage of home theater in mind, but I strongly disagree with those statements. I'm using the RC-70s in a two-channel system and they sound equally impressive, if not more, with music. Both imaging and soundstage are very solid with these speakers. They are on the warm side of neutral, which isn't a bad thing at all since you could listen to them comfortably for hours and hours. It seems that Energy isn't a well known name in audiophile circles, so it always grates on me I hear people tell me to "upgrade" the RC-70s with B&W, JBL, etc. John Tchilinguirian, the engineer behind Energy's highly acclaimed Veritas line, designed the RC series and also incorporated the former's aluminum-dome tweeter and tapered crossover into the series. Unfortunately, Klipsch acquired their parent company, API, and discontinued with the brand's cherry and rosenut finishes.

I haven't had a chance to listen to the CM9s, but I did hear the CM7s and thought they were overpriced IMO. While they did offer extremely good bass response for such a small enclosure, I noticed the tweeter had a metallic harshness to it which I didn't enjoy.

You can't go wrong with either, but it depends on what kind of sound you like. As long as you're using quality components, you'll be happy either way. If you decide to go with the Energy's, you won't get the snob appeal of the B&W's. But what you will get is impressive performances that rivals that of much expensive speakers.
Worth every penny paid! Best speakers i have ever heard with 1 exception (dynaudio). I love mine! Wait til they are broken in, whoa nelly! Your never going to sell them. For my ears, they are the smoothest speaker, accurate, just beautiful. A wee recessed for metal, but nice, as absolutely no fatigue in jigh freq! They perform WELL ABOVE their price point, you would need to triple your spending to get sound this good. Top tier company(rip) top tier speaker! Enjoy.
