If I may, I think he's referring to something like this at least : http://www.tnt-audio.com/clinica/sandblaster_e.html
Some will actually take the TT apart and install its mechanical parts on a heavier plinth :
The reason for either is that a TT is a lot more affected by vibrations than CDPs. With the latter at least it's easy enough to have a stable platform as long as the disc transport is good enough quality, as well as the chassis, since the laser reading it makes no physical contact. On analog discs, the needle makes physical contact not just through the spinning mechanism, but also the needle, which vibrates along with the cartridge from reading the disc as well as more of it from any vibration on the chassis. A heavier platform deals with some of those vibrations.
That would be great!
But there are a lot of other options, like a good solid hunk of butcher's block sitting on super balls. There are a lot of ways to end up where you want to be, more than one way to skin a cat...
If you can afford the time to make a solution like ProtegeManiac posted, so much the better.
