What would be the speaker setup? Yes, we are all head-fiers/headphone enthusiasts, but most of us are also "audiophiles" write large, also loving conventional stereo. (For some of us, love of stereo may even come first!) So a stereo setup will certainly be appreciated. In fact, it may serve as a great reference-creator for when people go back and forth between listening to headphones, to remind us what "regular" stereo sounds like from time to time. (Like smelling coffee beans between colognes or perfumes, or a lemon palate cleanser between meals, etc.).
If this is simply an interest-check, then my vote is yes! But Keith, don't go breaking your back when you've already bent over backwards to help make this thing happen.
In fact, if you don't already have a stereo system lined up (I didn't see one listed in your profile...) I volunteer my Paradigm Studio 10-based set-up... I'm sure others attending have superior systems, but again I'll put it out there in case alternatives don't show up soon. Note: I've been having some strange channel failure problems lately and haven't had time/funds to get the amp checked out (perhaps one of our sagely DIYers could take a look for me for free...) but the system mostly works.
Anyhow, someone, anyone, esp. Keith, let me know if you think I should bring my bookshelf speakers, amp (modded Music Hall), and sub (Velodyne).
I'll be there regardless, speaker room or not.
