Down here in the South East there are a couple but are by appointment only. I’ve been to a couple and frankly they have rubbed me the wrong way but I understand. The market here for most everything is pretty ridiculous with influencers thus hard for them to filter who’s who; who is a tire kicker and who is serious.
I requested an audition to go see and feel some amps. I felt very unwelcomed and there was hardly any interest in trying to win my business. I asked about taking the units home to listen to it and it was a flat no (I offered to leave a guarantee).
Forward a couple of months and a friend was going to visit for a listen of my system with my new amps and was bringing a friend of his. Yes, the friend was the owner of the showroom. "I remember you, man you have a very nice system, why didn’t you buy the amps from me.....".
I have had great experience with various out of state vendors who will give you a money back trial period. Give it a shot.
