Just clean a record with a VPI or similar, which is vacuuming the liquid and play immediate , as long as it is cool from liquid removing. It sounds harsh. Any may get damaged.

After apx. 30 min warm up ist sounds right.

Vinyl is thermoplast ( thus it can be formed whit a stamper).
Too much heat = deformation
Very cold = very hard

Yes, I'm fairly familiar with thermoplastics.

Unless the liquid is very cold and it is applied with enough quantity to absorb the heat and is left long enough for the heat to conduct to it, I can see no reason why the vinyl would significantly change temperature. Remember, heating, cooling, and thermal flow are dynamic quantities- you can't just drop in static or equilibrium values and expect to get answers that are correct.

********. You didn't report any conversation. You were talking **** about him behind his back. What you wrote of your "conversation" had absolutely no substance whatsoever. It was just trash talk.

It was Bob Pease who was talking BEHIND Ron Quan's back.
Then bad on Bob. But he's NOT doing it HERE.

And if you don't like Bob talking about Ron behind his back, then why do you feel it's ok for you to come here and talk about Bob behind his back?

It's only 200 pages if you go to the UserCP/Edit Options and set it to display 50 posts per page instead of a measly 10.

Perhaps it attracts pre-polarised posters....after all they would be moderated off of most threads, yet there appears to be no moderation on this thread - except of Mr JC - whose product it is meant to be discussing.

SY,

Well the noise theory I got seems to be pretty well shot down. So A quick test of yours, is the level of noise after wet playing the same on the outer grooves as the inner ones? Assuming damage is proportional to V squared there should be a 10-15 db difference.

Funny how old knowledge still applies....but gets forgotten...that's not so funny actually.
John, you have long advocated that the likes of 7th harmonic are the devil and I believe you without having substantiated your assertion - that said I will create a multitrack mix and hear for myself these nasties.
Also I have read differing opinions of the deleterious effects of 2nd harmonic VS 3rd harmonic production of amplification on the perception of music....what is your take on 2/3 harmonic and further what is your take on higher order harmonic production and sonic effects please.

Regards, Eric.

I await Scott Wurcer's discussion with Bob Pease. This will bring 'fairness' to the discussion.

IF you will ONLY Google, you can learn more about 7th harmonic and its 'problem' with the musical scale than anything that I can say here.
