Best audio shops in the Chicago area?


I am going to be spending some time in Chicago in the near future and would like to visit some 'user friendly' audio shops. Of interest to me are full range speakers and tube amps. Of course, I'm receptive to any audio product that might enhance my home system. A couple that I have come upon here in Audiogon are Promusica and Holm Audio. Any help fellow audiophiles in the Windy City could give me is sincerely appreciated!

Glenn Poor's in Champaign has some very nice components! Well worth looking into. Also, not sure if they're still around, but Red Rose (I think it's the more affordable Levinson line) was good as well. Not as big selection, but some very aesthetically pleasing items.
Milwuakee, only 1.5 hours away, has Ultra Fidelis, which carries some brands (Vandersteen, Rogue, ProAc) which I didn't see in Chicago; the Vandersteen 5's are worth a look. (doesn't mean they're not there, I just didn't see them).
There is a Glenn Poor's in Chicago on Grand as well. I Second Music Direct. You can listen to gear there as well as check out music and accessories.
Thank you all! All of these suggestions are candidates, as I will be driving in from the west (Minneapolis) and can visit the Naperville / Woodridge area on my way to downtown. Glenn Poor's?...I actually lived accross the street from their store in Urbana when I was a student at the U of I in the 70's. The Milwaukee store is also game as I head north to Green Bay after leaving Chicago. Again, can't tell how much I appreciate your input. Think Spring! - Steve
