Why "replace the IC socket"?

I believe it's because the contacts in the socket can oxidise leading to a bad connection.

The sockets used by B&O are not of the best quality.
They oxidizes, as Lee says, but they also lose contact tension, causing all kinds of faults.
I see it more and more, enough to replace the sockets on sight with one of a much better quality.
