Well, I've been watching this one and actually restrained myself for 10 pages or so...but here goes.
I think modeling the success of some of the bigger and longer running RAVES/local clubs accommodates this well. Each time I read the "after" threads it's about the FUN everyone had, pictures of great food, and/or some crazy liquor induced faux pas.
I really like the friendly pitch-in/GTG idea, which seems like the original spirit, even if some are dealers or manufacturers (just like NY Rave) present. For example, I (and Marbles) am somewhat centrally located here in NE Indiana, relatively equi-distant from Chicago, Detroit, Indy, Cinci, Dayton, etc. though a stretch to WI. In very close proximity are some brilliant manufacturers such as Bob (SP Tech), Robert and Steve (Ridge Street Audio), Klaus (Odyssey), Phil Bamberg (BESL and now, AV123), others further in Chicago, Steve (SAS), Gregg (Reality) and Detroit, Jim Salk. I had a great time at Marble's house a couple years ago and met some of these terrific people. There are a couple groups in the Detroit area already doing this, where I met Mark Schifter, Mark Seaton, Jim Salk, and Dennis Murphy. Bob did this in Denver during RMAF at a local home/dealer in Denver to great accolades from attendees. We all have much to learn from the vendors, so we should embrace them rather than somehow pit them against each other or worse yet, exclude them if they choose to attend.
On the Emerald Physics front, yesterday Clayton and I discussed showing the CS2's myself for this regional area simply due to lack of a dealer presence. I don't know if that would develop into a commercial interest or not, but I know I would enjoy doing it for AC friends and serious seekers here in the right context. I've already done it quite often for Merlin, Onix, ACI, GR, and I would gladly do the same for Bob at SP if I was fortunate enough to have a pair here. On the other hand, I'm less keen on packing the whole setup and moving it to hotels unless it was my day job, but on occasion I might consider it. As long as the time is my own terms, it's no big deal.
For the vendors, it's a great opportunity for exposure. As I told Clayton, ID marketing these days is the modern equivalent of an audio "Tupperware party". Maybe even good deals if stuff is for sale or freebies at the event. I still use RSAD's reference CD that Robert handed out as a freebie at Rob's house (sorry, no Poiema's). And then there was that lead on a power amp someone told me about, etc....
...and in the end, it is ALWAYS good fun.
