We usually don't have a big enough turnout to get vendors. Justin was at the first meet I attended many years ago, but it was also the largest meet I've been too. You're welcome to invite anyone once we have a definite date, but I doubt any vendor will show up unless we a lot of people showing up.
I'm looking forward to hearing the LCD3. I wish someone in the area owned HifiMan orthos. I may have a Smeggy made Thunderpants by the meet but that really depends on how backed up Smeggy is.
