I have a bunch of the RSD3. These are the 3" vinyl records that play on special players. I have several of the players also.
Pretty cool, but not for sound quality.

I got to get me some of this tiny vinyl.
Being a non-audiophile vinyl collector, I am excited to grab some of the new tiny vinyl product hitting the market. Novelty? You betcha, but I am needing a bit of novelty right about now.

Then again, there is some really, really, tiny vinyl, but it looks a bit hard to play.
