My wife and I weren't that impressed. Most rooms played some God awful music that we would never listen to so we couldn't make any comparisons. I was extremely disappointed in The Marketplace, not many sellers and everything was at full retail! We walked in and out of many rooms because we couldn't stand the music and nothing really moved us.
The last audio show I attended prior to the RMAF was the Stereophile show back in the late 90's in NYC. For one thing, there were many venders selling their products at good discounts and the rooms were much bigger and I enjoyed it more back then.
