Are the days of the audiophile (as distinct from audio supermarket) retailers numbered?

Gentlemen. in the age of the internet where increasing numbers of retailers are offering Buy-without-risk / Sale-or-Return for a month, are the days of the audiophile (as distinct from audio supermarket) retailers numbered?

No. Because there will always be a small interest in having good equipment and basically it's very difficult to buy good equipment unless you trust the person selling it.
