Yes! I have one now on my SL 1200GAE. Big upgrade over the stock mat or bare platter. I hear a more lively sound as well, but not in an exaggerated or forced way. There is more space or as you said air in between things, more like you are hearing live music. I bought it on eBay Japan for ~$250 IIRC, kind of on a whim when I was buying headshell from the same seller. No regrets.
At some point I'd like to compare it to Herbie's and the Boston mat, but haven't been in too much of a rush. LPs sound very good as is...
