Hope relative lurkers are welcome. I don't have any hi-end head gear to share, but I did just get back from Cali with a bunch of Monoprice junk I could bring (8319, 8320, 8321 IEMs and the 8323 full-size). Are drop-ins ok? I can't commit to the whole afternoon. You guys should charge me a drop-in fee.
The other thought I had for sponsors would be Heartbeat Distributions in Langley who are the Canadian Superlux distributors. I got their tour this summer - they're super friendly.
