Vinyl "bleed through"- need set-up advice

I read this forum regularly and am amazed at the knowledge that is shared. I need your opinion/help. I have recently got back into vinyl with a Rega P9/Dynavector XX2. The issue is : I can hear what is coming up next on the record faintly a splt second before it actually plays- it kind of "bleeds through". At louder volumes it really is quite clear and annoying. I had the cartridge installed by my dealer with whom I have had a very long relationship- did he miss something? Any/all help is greatly appreciated.I use Naim amps if that helps.Thanks!

With respect to Polk432, if adjusting your cartridge reduced pre-echo then I believe you somehow adjusted it farther from optimal rather than closer to. Not saying your alignment isn't better, since the Mint is superb. But you may have inadvertently changed some other parameter like VTF, VTA/SRA or anti-skating.

As others have posted, true pre-echo is caused by tape bleed-through and/or overly thin groove walls. Either way, it's pressed into the LP. Therefore, the more resolving and better adjusted the rig, the more pre-echo you will hear.

Dusty,

Good example, and there are many throughout that song. The one you mentioned is so huge it's often audible over the radio. Many LP's have a pre-echo in the lead-in groove, especially if the opening chord is loud, as you said.

A stiffer test of system resolution is the ability to reveal POST-echoes, which are much rarer and often smothered by hall decays and real echoes. I've heard it on 1 or 2 classical LP's, unfortunately I can't remember which.
