To me, part of the problem with two channel audio is the ''snob'' or stand off factor that potential new entrants find. For those of us that are ''in'' the system it may well be less of a problem, but to the newcomer it can be, and I would think, is, a daunting prospect. Just for a moment imagine you know that you enjoy music in the home, and decide to lavish a little of what is becoming a rare item, your spare cash on a home audio system. Where do you start. The high street is bare, other than the odd branch of Richers. The monthly comics are little real help, either being much more TV/movie biased, or wandering down the high ticket esoteric path.
You do, finally manage to discover that a raft of makers do offer products that may be of interest to you, but how do you get to hear them. Well if you are lucky, you may find a dealer around your town that stocks one, or at a push two of the entry level brands. So you wander in, as a new entrant you are unlikely to be aware of the booked demo system, to be faced with having to make your booking to listen to something. If that has not put you off the idea, and a bigger TV from comet has not become more interesting, then you go back to hear. The next thing you know is that your simple cd replay system at £1500, has after a few changes of component become a £3k plus system that you can not afford, then the man tells you he wants another stack of cash for cables and stands.
If the industry as a whole wants to try and stay viable, then a better way of introducing entry level gear to potential purchasers has to be found. It will take a change in attitude across the industry to do it, probably more of a joined up advertising campaign for the idea of music system, rather than a buy my amp/speakers thing in what remains of the specialised press.
Put simply, get people into the ethos of two channel music systems, and they will ''upgrade'' themselves, ignore them and the industry will continue to die.
sod the hi-fi, listen to the music
