Wow, I had given up on a Winnipeg meet, but apparently too soon! I would be happy to bring all my gear (DT770 pro-80, DT990 250, Turbines, CX300, PA2V2 and Compass with the three opamps. Nothing balanced here either.
As far as meets I've been to, the one meet I attended was out in Calgary where we rented a meeting room from the library and set all our stuff up there. The important thing is having it somewhere where you 1) have enough places to put stuff and 2) have enough electrical outlets to plug things into. That said, if there is a house that fits these requirements I'm happy to do it there since it would save a bit of money and there are no time limits. April sounds good to me too as long as its not on the 26th.
As far as other people's equipment, this looks pretty exciting so far! I've been wanting to try the SRH-840, ATH-ES7, RX-900, HFI-580, and of course the HF-2 for a long time, so any and all of this gear looks good to me!
