Ok, I'm now all in. I've had three triple 8's across the front and two slant 8's for rears for just over a month now. I'm driving them with a Parasound A21 for the front L&R, a Parasound A23 for the center and a Parasound A23 for the two rears. The head unit is currently a Denon 3808 but I will soon be ordering an Onkyo 80.1. My only two sources are an Oppo BD83 and a Toshiba A35. The rest of the equipment is a 130" X 54 1/8" Seymour Centerstage XD screen, two MFW15's, a velodyne SMS-1, and a PS Audio Power Plant Premier. Projector is currently an RS20 which will be replaced next week with an RS35.
This past week marks a turning point of sorts. I have sold off my two channel rig completely. I was running a two channel setup alternating between Revel F32's, M22's and Magnepan 1.6's for speakers with a Conrad Johnson Premier 17LS tube preamp and Marantz SACD player. Over the past week, I sold all of it (except the Marantz which is moving to a smaller setup upstairs).
I'm now content with just the triple 8's for my music and HT needs. I'm even happy with the sound out of the 3808 driving it all. I've lost some resolution and I don't get that goosebumps along my back feeling quite as often but overall, this is one helluva great sounding system. It somehow just does it all right. The only fault I can find is that it doesn't have as deep a soundstage as I would probably like, but the width is huge. Cranking the sound to -15 is really, really loud in my smallish room (133" x 18.5').
The Mags excelled at all things vocal with female vocals sounding amazing. They lacked in HT and hard rock. Where they lack, the Triple 8's dominate. Where the Mags excelled, the Triple 8's don't quite match, but they aren't that much worse. I've yet to listen to large orchestral pieces but I have the feeling they will sound amazing. Compared to the Revels, they are again not quite as detailed. I got the feeling with the M22's that I could hear farther into the music. However, the M22's would break up and sound a bit harsh when pushed to high levels. I prefer the Triple 8's in every way over the F32's but that isn't too big a surprise as they were my least favorite speaker. Anyway, I think I'll stick with these for quite some time. I'm also excited to move to the 80.1 with its balanced connections and dynamic eq and possible pro audyssey.
