I no longer live in Louisville, but I am from there and there are not many options when it comes to audiophile gear. There is a 98% home theater shop out towards middle town, they carried B&W, Classe and maybe Krell, can't remember. Not set up for a dedicated 2 channel consumer.
A great little find however exist in the Highlands, on the corner of Baxter Ave & Payne St. there is a little hole in the wall called Magnetic Tape Recorder Inc. Charlie Green is the shop owner, who mostly works on repairs of vintage equipment. I have personally used them to repair my Pioneer M-22 Class A power amp & some of my Dynaco gear. The work is thorough and he stands behind it. Occasionally he will have some awesome gear for sale in there as well. He had a Clayton Audio S40 for sale, which I am still pissed at myself for not purchasing it. Anyway if you need something fixed and dont want to ship it, check him out.
