It would appear from the number of posters who say "there's no dealer within hundreds of miles of me" when asking us about a brand and/or model, that there are many areas of this nation that do not have either the population density or the regional wage scale to support a hi-end audio store of even modest offerings. Outside of densely populated, high income urban areas the big box retailers rule everything that doesn't sell mail order or online.
Eventually Mac and other manufacturers will have to accept that reality and respond accordingly. However, it is likewise true that manufacturers of that tenure and stature will be sought after by informed consumers, no mater how obscure their place of residence. It is also instructive to consider that there are marketing intermediaries like Audio Advisor and The Needle Doctor who do a fine job.
Brick and Mortar audio salons will be as scarce as Ferrari dealers in the near future and so will be the number of consumers who can and do choose to buy from them.
Good thing for Mac and their like that there is a worldwide market to be mined.
