I'm gradually replacing Polk LSi speakers in the HT. First was replacing the mains with Acoustat 1+1s. I just purchased an MMG-C center. Wifey and I are planning a major kitchen/family room remodel next spring where that wall will be gone and the system moved to the opposite side. Once that's done, I plan to buy MMCs as surrounds. When I spoke with a rep at Magnepan, he initially tried to talk me out of buying this model. Naturally, he thought the CC5 would be a more appropriate match to the stats. I explained that I rarely listen to MC music (have one Telarc SACD) and use the center primarily for dialog. And like the 1+1s, it's a full range design which appeals to the coherency freak in me. It's efficiency more closely matches the stats so I needed to adjust the level trimmer on the processor for that channel. The Emotiva XPA-5 amp is rated for 300 watts/channel into 4 ohms so its 5 ohm value should allow for plenty of power.
