At the risk of being branded a heretic, I think we need to keep some perspective. All of us here on AVS are audio enthusiasts to one degree or another. However, the amount of time, education, and financial commitment that we can put into this hobby are radically different. Not to mention, the amount of 'trust but verify' we can tolerate.
For some of us, simply running basic Audyssey room correction according to a systematic method is better than nothing. For others, moving up from consumer to the Pro Kit is a step up in dialing in our systems with more measurements and choice of crossovers, understanding the nature of mid-range compensation, and taking the first steps away from 'trust' to 'trust but verify' (by questioning the degree to which the Pro 'After' charts have validity). Use of room treatments, sub/speaker placement, and the like overlay all of this, but may be ideals rather than 'must-haves' for the less dedicated (or obsessed LOL).
OmniMic has certainly been valuable for at least me in thinking about how Audyssey, my room, and speakers are doing jointly. But I feel that we risk delegitimizing others that have been long-time participants on AVS if using REW becomes the single standard towards how a HT system should treated before and after Audyssey or other RC.
Right now, several of us (almost entirely Pro users IIRC) are progressing into REW training/use from either no measurement tools or the OmniMic. But not everyone will want to come along for the ride unless that hard-core enthusiast, and a few others with advanced acoustic training, deliver on the 'promise' that has generated this burst of enthusaism. And some of us may not want to stay on the bus, or have the energy/interest in the optimal string-based techniques for placement of pink fuzzy things....and this needs to be respected, at least in a general Audyssey thread.
While I understand the enthusiasm for REW (I'm getting my own UMM-6 mic within a month, hopefully), I'm still needing to be sold that REW, and the measurement philosophy that has been stated in almost absolute terms, is superior to what until three weeks ago was the 'norm', and not just an artifact of the software they prefer. Using REW should be preference, not a religious commandment.
Having said all that, let's take this whole REW thing and put it in the Pro thread, or better yet the new REW thread, where it belongs.
