Thsalmon beat me to it. Audio Insight and Audio Concepts are also at the top of my list. Both have nice stuff, and good listening rooms, although i get do mixed treatment at Audio Concepts, but hat maybe because I am young. Hillcrest HiFi is mostly Home Theater, and they do have the worst listening rooms ever. For sort of a sideshow experience you could go to Tweeter Etc. on Park and 75. You can stroll by their Car Stereo room as you head towards the the rooms featuring Martin Logan and Vienna Acoustics and Sanus Faber all powered by nothing less than B&K, and all sharing rackspace with a Bose CD player thing (with a sold sign on it). It is Las Vegas surreal. Have fun in the Big D.
