Friends, we are a dying breed, ageing and falling in numbers. Shops, high or low end, can only be supported by a customer base, it is tiny. Take a look at the magazines, they were sold in the 100's of thousands in the 70's. I think it was reported recently that HiFi+ had a worldwide sale of 6 or 8000, that's all. I know they have an online version, but the market is tiny.
Paradoxically we have more and more brands, often selling a few high cost units a year, built by hand, to order.
These numbers, this market, can't really support expensive, bricks and mortar stores. Even in large conurbations, I do'nt know how they survive. In Minnesota, where Great Northern Sound was, till it closed, sadly, you do'nt really have a passing trade.
