erm. I read this claim with some astonishment at the time. They can't have meant a stonewall cutoff, it just isn't plausible. Anyway, if we really are down to 8KHz after 80 plays, how come I can still clearly hear the dog whistle (typically 16K+) at the end of my 25 year old pressing of Sgt Pepper - a record which has been well and truly caned on a truly awful mass market TT (an Akai no less) prior to my introduction to HiFi.
