Another vote for Premiere entertainment!
I am in Las Vegas on business this week and found them from this thread. I called and made an appointment for 8:00 am(!) and let them know what I was interested in. I had to call back and reschedule for another day, no problem. When I got there, Jim greeted me by name, he had a room all setup with the speakers I was interested in hearing. This was really helpful for me, as I was on a tight schedule.
No pressure, nice tour of the place, left me alone with the equipment, invited me to position speakers as I liked.
Pretty amazing, considering I let them know I was from out of town! I offered upfront to pay for their time (I hope this wasn't insulting), which they declined.
This store might not satisfy the most serious audiophiles on this site. I didn't see any tubes or turntables (I didn't ask as I wasn't looking for them). Home theatre occupies a good deal of space.
A decent range of electronics from Marantz, Rotel, Arcam, Bryston (and Anthem and Proceed on the HT side). The only quality 2-channel separates were from Bryston, no complaints from me.
A great selection of speakers (which is what I was looking for). All available for demo: B & W (including N802, N805, and CD-9NT), 2 different sets of Martin Logans (I listened to "Ascents", I believe), Vandersteen 3s, a "local" make (RBH), and Paradigm Reference. Lower-end models from B&W and Paradigm also. Again, not the highest of high-end, but right in my range.
They seemed quite honest, are willing to ship to me because they have spent significant time with me in their shop, and so they consider it a "local sale". I will strongly consider purchasing from them if a speaker they carry makes my final cut.
Overall, a great experience.
