Over the years I have watched the rock bottom price for second hand and bargain give-way loss-leader classical music CDs fall, slowly but surely. What I mean by this is the lowest price that a serious classical CD will be offered for. I don't mean something from the front cover of a magazine with lots of mere snippets; I mean the real deal. A decade ago it was about £5. A few years ago it was about £3. Now, it is £1.

I bought these five CDs from Neil's classical CD barrow in Lower Marsh (which is the same street as Gramex the second hand classical CD shop is in), a couple of days ago. They aren't all of them all that super-desirable. But they are the real thing. Real classical CDs, of great music, very well performed and recorded. I've just listened to the Jupiter Trio CD, which was released only this year by the way. It is excellent, the Shostakovich in particular being outstanding.

Prices still have a bit of falling to do. These CDs were £1 each, but others at Neil's were £3.50, and some were as much as £7.50. Gramex often charges only £3, for older stuff, and sometimes only £2. But Neil has now set the floor for the market, in London anyway (which is, frankly, all I really care about – this is why you live in a city for goodness sake) and all the others will be dragged down.

The charity shops are all over the place, often charging more than the full price for their CDs. That's one of the signs of a plummeting market, when the amateurs often charge more than the pros, because they just don't know what has happened to the market they've wandered into.

Naxos CDs are starting to look overpriced.
