Dealers with excellent listening rooms?

They're probably long gone, but Imperial Sound in Tulsa, OK in 1983 was great. They asked what gear I wanted to audition, then told me to pick some albums off the MoFi rack to listen to. They moved a Tandberg stack, a pair of ADS L1530 speakers, a Nakamichi ZX9 and a Yamaha PX-2 in to their listening room-while I waited. When I was ready they made sure I was up to speed on the gear, then left me alone. I spent a couple hours in there.

 Turned out to be a good investment for them. I wrote one of the biggest checks of my life that day, bought everything, including the albums. LOL

Qudos and Strong Agreement with Quintessence in Morton Grove, as well as Audio Salon in South Florida.

My personal in-house favorite is Salon 1 Audio (Eric) in Ormond Beach Florida.

If you can come to Florida, come in February on the 16 - 18 to attend the Florida International Audio Expo. 15 Hotel Floors of Exhibitors for 3 days. Since 2019, and growing every year! Lots to listen to!

Seems mostly like east coast suggestions. Bummer, I’m on the west coast. I’ve demoed brick and mortar shops in the SF Bay Area, the LA area, and at several audio shows.  I have also been to the Magico factory demo.  I’m curious if I’ve missed anything by not demoing other excellent sounding systems.

Initially getting into this hobby, I wanted to demo the best systems I could, then try to closely replicate the sonics within my budget.  

Definitive Audio in Bellevue, Washington has a couple of well set up rooms.  But I'm looking forward next weekend to going for the first time to Shibuya HiFi - a Japanese style listening lounge in Seattle.  They have a few rooms, and I believe the room I'll be listening to John Coltrane's "A Love Supreme" in is the one with a vintage (1970's) pair of Klipschorns driven by either Luxman or Marantz electronics.

Suncoast Audio here in Sarasota has an excellent room and some stunning gear including Magico, Audio Research, B&W, and many other even more expensive brands.  Mike and his folks are excellent to deal with.
