My initial plan was Phantoms and the whole Performance HT. However, in the listening room with same source and amplification I was able to switch between the Monitor 7s and the Phantoms instantly.
I was surprised by the diffference between them. While the Phantoms kick *** (in fact, I like them better than the Energy Conoisseur C5, and I'm a big Energy fan), the Monitor 7 tweeter is awsome and that low frequency driver really lets you feel the bass.
It's a tough decision because the Performance line looks so damn good now, better than the Monitor series IMO, but the sound is a noticable step up, and that goes for the CC370 also (their different drivers than the CC270 and what's more important than the centre channel?). Be cool
