Pressing Issues

After many given reasons, I had settled-in on my own non-scientific answer.

The stylus is picking up the future music from the other side of the groove because the wall of the groove is thin and the stylus is very sensitive.

I have a question for those stating that this is only caused by tape magnetization issues. Why then is pre-echo still audible on some direct-to-disc albums that were recorded directly to the vinyl disc master without the use of any tape medium?

I agree with you on this theory Kennythekey, which would leave me to theorize that the last lap of the groove at the center of the lp should be the quietest groove on the record.

Some copies of original editions have it too. I have three copies of Bitches Brew but only one of them has it. At least I hear nothing on the other two.

The most common source of the "problem" IS tape print through. You can hear it on CD reissues of music that was originally recorded to tape where the producers of the CD do minimal or no processing in the remastering process. Good examples are the incredibly well done, though expensive, Esoteric XRCDs.
