I'd attend a meet anywhere in the Bay Area. I just joined this forum and am bummed since I see there was a great meet in San Mateo just a couple months ago.
Quite a few people posted and said they would have attended but for other commitments.
I note that Sennheiser has a research lab in Palo Alto, by the way. Perhaps they could be enticed to bring a set or two of the HD800s.Media Invited for Peek at Sennheiser's New Research Facility in Palo Alto, as Innovative "Sennheiser Sound Tour" Comes to Town - Yahoo! Finance
