I made some from o-ring string which is what the ones being sold on ebay are I believe, I don't think that there is a massive difference to the sound TBO but they do make the platter ring less if tapped but I do think that you can go too far with damping and it can suck the life out of the music if your not carefull.
Although I haven't done it on the 401 I found that sticking the platter mat down on my lenco g99 worked wonders for the sound.

Seconded - and I still have some of the rubber left.
You only need to cut to size and use superglue and bingo! you have HiTEkHiFiplatter ring.

A damped 401 platter reveals the HF... more damping makes it cleaner...does not suck the life out of it although I could have thought it did before damping the hell out of it.

I'm not convinced by nitrile.....I had some, it was great for 6 months but it stretched and became loose. OK you can cut it and re-glue but it's a hassle. I'm not sure what the proper rubber ones are called but Vic at Trans-Fi has some, they don't need glueing either.

i found big fat elastic bands were more effective than o-rings in damping the ringing
don't look very attractive though !
the outer part of the platter seems to ring more than the inner part (bit like one of those singing bowls)
i think this is why rings and elastic bands have more effect than sticking blue tack or similar on the bottom of the platter. tho the blue tack does make a difference.

anyone heard one of these yet ?
I have a Salvation, I'm a beta tester. I also have a 301 in a twin tier slate plinth. The 301 is relegated to be my second deck, the difference is significant.

Hi all, I can certainly recommend the platter rings. I use two on my 401, along with a cork mat. They certainly make a significant difference. Much cleaner high frequencies with less smearing.
