Hi Dave,
RMAF 2019, they had it at the Gaylord Resort(YUGE,YUGE,YUGE), very close to DIA, which made things easier for me since I was picking up a friend to see the show. Usually RMAF took up what felt like the whole Marriot at the Tech center and the new digs made it feel quite small.
Went thru floors 11-8 and I think floors 3 and 4. They had a lot more of the larger rooms for various displays, and some of the speakers fit well into the rooms. My friend walked out with a reel to reel tape and my wife a nice harp piece on CD.
Got to hear and see some of the speakers I've been reading about, Rhea speakers and Raidho Acoustics. The Rhea sounded sharp and warmish all at the same time, but I'm not sure if that was Bryston playing a part as well. I didn't catch any Martin Logan Electrostatics, we didn't go back for a 2nd day because we were all tired.
I did see this and hear it, and it was a trip! It sounded good, looked so freaking cool, It had a sense of "fun" to it. I kept on feeling how it would fit well in a small NY apartment.

Nothing really blew me away at the show, there was a nice room with Esoteric and Audio Research and some $35,000 dollar speakers made out of granite that was quite nice.
