As far as I'm concerned the Ayon/Lumenwhite is probably the best sounding system I've ever heard. Too bad it's way out of my price range.
I had never heard of PranaFidelity before but I really liked what I heard. The 'bookshelf' speaker just blew me away and it's a two-way. I want a pair of those!
The Salk speakers with the Accutron drivers were very nice. I could live with a pair of those quite easily.
The Fritz speakers were quite nice. I'd like to see Fritz make a 3-way or 4-way floorstander similar to a Legacy Audio Focus SE or Signature SE.
Speaking of Legacy Audio, I'm a big fan of their speakers. Wonderful stuff!
I don't care for horn designs so I didn't care for the Volti room. Too bright and harsh for my ears. There was another room that had a pair of horn design speakers (can't remember the brand/name of the speaker) but they were also bright and harsh sounding to me.
