I would suggest Holm Audio in Woodridge. Mike Holm and his staff are down-to-earth folks who are friendly and well informed. They don't have that attitude that you find in many other shops. They have a wide variety of new and used gear and they have a very reasonable audition policy.
High End Quality Retailers in the Chicago, Il Area
I am trying to introduce my nephew to high end audio. Unfortunately, he lives in Chicago, IL and I live in California. I need a list of quality retailers in downtown Chicago (or the Chicago Area) who will work with him and give him good advice. Can you please post some retailers that he should visit? Thanks
