"I agree with Tpreaves. Excellent observation. Set up and "the room" are also frequently used at shows to excuse less than excellent sound."
I wonder. Having been to only a few shows, however, some displayed systems that are a few hundred thouhsands dollars worth of equipments, I was always rather underwhelmed. Coming back home to listen to my own system is always a treat after a show. Even speakers that I own or speakers that I am familiar with, from friend's system etc always sound quite a bit worse at show. Certainly there are some good sound at a show but it seems that generally, you'll be lucky to hear 40-50% of what the system is truly capable of.
I wonder which system have anybody heard at show that sound as good or better as a comparable system that you have at home?
