RMAF Etiquette

I have attended each year and I agree. There are certain rooms where they have closed demos and every one is quiet, but then the rooms get crowded and hot. I have determined that it is a place to see and hear the equipment but not make a buying decision. 

My only suggestion is if you are really interested ask the vendor if you can make an appointment at closing time, I did that a few years back and it was nice, and I was able to really determine that the speakers weren't for me.

Scheduling a session late is a good idea.  Maybe people don't attend RMAF to buy products as much as they are there to socialize.  I just found it very odd that the majority of people would speak loudly during auditions of equipment.  I found it incredibly distracting to the point of annoyance.  It reminds me of going to a movie and people talking.  

Maybe i am in the minority but if I was shelling out thousands of dollars as a vendor my goal would be to have my equipment shown in the best light and make some sales to pay for my expenses to attend RMAF.  

I agree, it is rude and inconsiderate at minimum. But where do you go these days and not find rude, inconsiderate and disrespectful people? I know that is a blanket assessment and I apologize to those whom take offense. I don't want to turn this in EtiquetteGon, but I do share your sentiment. It's an AUDIO show and the gear should be heard. But as mentioned I go every year and it seems to be a gathering of friends as well and that part invites the talking, laughter etc. Obviously the vendor could control it by telling people to be quiet, but they can't risk offending potential customers, dealers or prospective dealers.
Either way I always enjoy the show, I just wish it was a different venue than the DenTech Marriott. Parking and elevator accommodations are much less than favorable.

An audio show isn't a place for serious listening any more than an auto show is a place to test drive a car.  It's a meet and greet, industry and friends event intended to showcase product.  It's really about manufacturers and distributor/dealers with the public there to help defray the costs.  Use it to narrow down what you want to seriously listen to at a dealer.
