audition spots in los angeles

i am in l.a. for the next month. i am hoping that some of you can recommend a shop where i can demo equipment. i come from a small town in alabama so there's not much to choose from. with a lot of research i've ended up with a pretty synergistic system, but i'd like to hear some of the more unique gear such as vtl, etc. i won't ever get that chance back home so...let me know who's good to deal with out here. thanks, brad hilliker 2out2sea@msn.com
