AXPONA 2017 Protocol


I need some wisdom from this community. I'm attending AXPONA for the first time on Saturday, April 22. I specifically want to hear a selection of certain speakers in order to narrow down what I plan on auditioning in my home. So, is it encouraged or frowned upon to bring a USB with various musical selections on it and ask for the USB to play through the systems being demonstrated? Also do any serious price negotiations occur at AXPONA, or is that expected to happen at a later time in a more private setting? Finally, I would appreciate hearing from veteran attenders the absolute one thing I must experience on my one and only day and also the one thing I should not waste my time with at the show.
I look forward to your insights and advice.

@m-db Thanks for the post and insight. At AXPONA 2017 I heard what I I needed to hear and ended up with used Joseph Perspectives in terrific condition. I bought them here on A'gon. Couldn't be happier. I have them paired with a new Jeff Rowland Continuum S2 Integrated (JRCS2). The JRCS2 is still breaking in--it is now at 450+ hours--it grows better with time. @guidocorona has posted elsewhere on A'gon that Rowland amps need lots of breaking in. Everything he has posted, and commented on to me privately has been spot on regarding my Rowland integrated. (Thanks Guido!) As I sit here typing this response, I'm listening to Francesco Cafiso's "3" and it is magic. I've invested the time to place the speakers in what seems to be the ideal location for my room. It makes a significant difference.  
@astewart8944 ,
You are welcome. Some songs are really good and some are demos to impress!
