I still remember first hearing "the Missing Link." Later in a dealers (remember those guys), I heard it being used to wow a customer. When the dealer was called to the phone, I told the guy to play to ask for a disk that you are familiar with.
I now find most of these disks still outstanding sound but weak performances. I seldom place any of them. Many, especially Sheffields were transferred to cds. Several were, indeed, redone by FIM and are quite good soundwise. Many of the d2ds were abused using the Decca London cartridge. It was a very dynamic cartridge and sounded "real" with these disks, but it loved to mistract and damaged many. No doubt including many of mine.
