The problem with direct selling is the lack of any real comparison aside from your own existing system. You have the same financial hit of buying from a dealer (i.e. the thing is inevitably worth 20-30% less as soon as you’ve bought it as that is what you’d lose moving it on) but with no comparable new products at hand to contrast and compare against. In most cases it makes a lot of sense, I buy huge amounts of stuff online, but for something as subjective as audio if I was a new buyer (I’m not, I buy second hand to avoid the depreciation) I think I’d want to hear how it stacked up against competition at its price point.
Back in the distant past when I did buy new I usually visited quite a few dealers to hear what was on offer from the different brands. I quite enjoyed that part of the purchasing process and kind of miss it now I’ve migrated into the vintage audio collector market. I’m also far from convnced by the “savings” of a lot of online-only kit and I’ve very seldom noticed any real correlation between price and performance. I can think of a fair bit (which I won’t name) which seems decidedly expensive compared to some of the big names when one looks at build quality, facilities and component costs. Ok, a lot of major UK brand kit is made in China these days (Quad, Audiolab etc), but even so that is the market the little direct seller guy has to compete against. Not an easy market at present so there is certainly plenty of room for different approaches though.
