I can only assume that the majority of your records don't start with a loud chord, or you play your records quietly. The great majority of my LPs do not suffer from pre-echo, but some do and it is definitely audible. You will only hear the pre-echo when the silent groove is one revolution away from the start of the loud-starting track.
I'll try and find some examples that you might also have.

I'm Corne.
Think the quality controll has a lot to do with it. Older lp is more likely that it will shine through as the TT of the day was not as clean and sensitive as what we have today so no one knew to avoid it. Next will be masts production how fast could they turn out 100 000 lp's to the masses who dont listen to music just the sound from the boxes with the round things in them that vibrate. I try to find limited production/ reproduction runs they seem to sound better on my avarage TT. I dont have 60k to fork out plus im to deaf to ever warrant that.

Where the pre-echo results from magnetic tape print-through, I presume this occurs throughout the whole length of the tape ie. each wind of the tape on the spool contaminates the adjacent wind by superimposing a faint copy of the musical information it carries? It is only in the case of the first wind that we can hear it, for the simple reason that the adjacent tape is blank?
I have to say I do not understand the explanation of how a pre-echo results from the operation of the cutting lathe. Why would the "heave" in the vinyl material which results from the cutting of the adjacent groove just happen to leave a sound which is identical to the music being cut? Surely it is more likely to be some sort of vague "negative image" of the activity in the neighbouring groove?

I'm not convinced it's the cutting lathe which is responsible for some pre-echo. I suspect the stamper and pressures involved when the the vinyl is soft. Adjacent grooves being imprinted with a subtle echo.

Congrats Barry, nice to see an argument backed up with source material and an interesting read.
Not enough of this in my opinion, with urban legend/Chinese whispers being repeated over and over in many cases on the internet, without any reference to where it started.
Not withstanding that Tape Burn through is also a real thing, so one or both may be contributing on a case by case scenario.
Good information all round.
