The mastering of vinyl...

Its a bit more complicated than that.

There was a good feature on this in a recent SoS - you might try searching their website ( i think) but i think it may be sufficently recent that its not online for free yet.

Around 17K they put a limiter though, since the cutting needle oscillates too fast for the media and starts "digging" in the groove too much if the amplitude is not specially tamed.

Anyway, in most clubs the weight on the needle is too much to avoid the needle jumping from the vibrations on the stage. The extra weight results in further top end attenuation, hence the best thing to do is to either avoid jumping up and down on the stage (tell that to the DJs and the punters that are hanging from the trusses on the stage...etc) where the decks are on, or hang the table where the decks are situated from the ceiling. That is what I used to do during my live sound days, so every one can jump all they want on the stage and have the top end from the rekkidz coming through crystal clear.

No (serious) mastering house hi-passes dance mixes at 50-40Hz as you loose all the frequencies that you can feel besides hear.

Peace out.
