I'm pretty sure HiFi Buys is the only thing left unless you consider Best Buys to be high end
HiFi Buys carries Wilson, Revel and B&W speakers. Electronics include McIntosh, Krell and Levinson.
When I was there in January they had the Wilson Duettes and several B&W bookshelf speakers. If you go, see if TJ Goldsby is there. He was a good guy and very patient with my auditioning. I ended up buying a pair of Wilson Sashas from them. Good prices too.
