Hot Stamper - myth or reality?


Can someone please explain to me exactly what is a "hot stamper" LP? I figure that it's an older, original pressing of an album, but so what? If that's the case, then wouldn't every old LP be a hot stamper? Is there something special about a hot stamper pressing that differs from just an ordinary first, or older, pressing?
Some of the prices I've seen here and on other sites (Better****.com)are astronomical (and ridiculous in my opinion).
I'm beginning to think it's all a scam or a marketing ploy with not basis in reality. Unless someone can explain to me why they are better or what's so good about them.
Advice?

I personally believe there are large differences between pressings. This includes record plants of first issues ie monarch vs presswell Sticky Fingers. This is why it is so fun collecting records. I have picked up some "hot stampers" from the bargain bin and they always sound very good. I don't think you need to pay the premium, as these are regular pressings they have just done the work for you. The process of mechanically cutting and pressing records creates very audible differences that imho can change a record from dull and flat to thrilling and involving.
I have certainly heard the term 'hot' applied to a particular mastering, the best example of which is probably the 'RL' cut of LZII. It sounds dramatically different than every other copy of that record I have heard.
>Qdrone: thanks for that link, great video, plus a good critique of Hot Stampers!
I didn't watch the video. Does Michael use the term 'hot stampers' in the context of Tom Port's offerings or generically, to refer to recordings that were mastered 'hot'?
I don't think he uses the words, but he does mention Tom and what he sells. It's good to watch the video, very informative.
