My view through the keyhole -
Was in Montreal earlier this year. Discovered the McIntosh dealer was still in their same location as when I first stumbled across them in 1990. It's a neat place, now carries B&W, and looks very much like the high-end shop that it is. I was mostly by myself when I was in but they do not look like they are hurting for business in any way. About a 20 minute walk away is another audio shop with headphones, TT's a smattering of tube gear, components, speakers, and a ton bluetooth audio systems & accessories. When I went in I was most definitely the old man in there and doubt anyone was much over 30. It was buzzing too. OK sure, it's Canada and a different market but I don't believe they are that much different. Plus, the shop (Layton Audio) has been there for a long time. I can recall ~10 years back when they looked like many of the dying audio salons in the US. Clueless and not sure what the next move was. To my eye it looks like they sorted it out, embraced the market change as well as the customers, and went for it.
