Turntable Pre-Echo Sound....?

When I turn my system up fairly high, I can make out a faint "pre-sound" of what is about to play, with the beginning of the songs starting very, very quietly about 3/10 of a second before it actually starts.

At I thought it could be my stabilizer brush fibers accidentally acting as little styli ahead of the needle, but it does this even with the brush locked up.

Equipment:
Linn Basik TT
Linn Basik Plus tonearm
Shure M97xE cart
Pro-Ject Phonobox preamp
Harmon Kardon AV240 receiver
NHT 2.5 speakers
Cheap interconnects

Thanks in advance,
Dusty

Eldafort says, "You can only hear pre-echo during a silent groove, but it actually goes on throughout the LP, and constitutes a form of distortion".

Hello, are you sure about this? I have a number of LPs with pre echo. I have never thought about this possibilty.
I must say though that I have never heard any detriment to the sound except for the pre echo. I guess my question would be; are you sure that it continues throught the record or is it lmited to certain areas on the LP? I will listen with this in mind the next time I listen to an LP with pre echo. Certain aberrations on LPs auch as rumble, distortion, groove or vinyl noise can be transient, is pre echo?
