Any good high end shops in Indianapolis?

75 yo friend on Kauai needs to replace her amp setup with an integrated to run Gallo 3.1s. i have sent her feedback from some other postings about this. Now she needs to go to the Mainland for personal reasons to the Gary, IN area. She asked if I knew of any high end shops in Indy. She is wanting to hear what she buys and figures if she hears something she likes, even if a bit more costly, she will know what she is getting. SO, any shops you can recommend where they have demos and wont be jerks to a 75 yo lady?
