Anyone familiar with Stack Audio Stabiliser and / or their turntable mat?

I should mention that the mat's sleeve it arrived in said a record spindle weight of up to 500 gm is ok (my F/R is over that).  Doesn't matter as I'm leaving the Stabiliser on there.....

My Stack Audio record mat came. I've now compared it to the Oyaide, using the Stabiliser with both.  The Serene Surface Mat is 3mm silicone, with 4 small nibs spaced on the record support surface.  There's a nickel-sized circular cutout on the underside of the mat below each nib.  Why this does anything is beyond me, but this is a no contest deal.  Wha's better?  Seemingly everything: bass, table, details, depth and width of soundstage.   I think I'm hearing harmonics that weren't there before.  The Oyaide is a very good mat (rubber with infused tungsten, 5mm) but there was no need to belabor the deal.  The Stack mat/Stabiliser combo is just clearly better.  Definitely worth a try. 

Well, that's timely.  I just got my Stabiliser and had it on my Technics SL1210G all day in a comparison with the weighted clamp I've been using (Fern/Roby, 700gm) plus the KAB screw-down clamp I just got.  I had done a mat comparison a couple  days ago between the stock, Herbie's, and the Oyaide.  That was using my weighted clamp.  The Herbie's was good but a mite thin (sonically) although I could live with it. Both the new ones beat the stock, and I decided the Oyaide had superior resolution and a bit better bass. I"m more of a detail guy than a bass guy.  The Oyaide is unusual in that it has an extra millimeter on the outer rim, so some people say it works best with a weighted clamp. This is important considering the Stack basically weighs nothing, like 3 ounces or something. I did have to readjust my antiskate with that new mat. Now, I should say my original goal was to have the Stack mat to compare with the others and to use with the Stack "weight", but it hasn't come yet and I did just email them.  First I compared the weighted clamp and the Stack.  It became pretty obvious that the Stack had better detail and imaging. The bottom end was fine, and I started wondering about that with the weighted item to the point that I think the F/R darkened the sound comparatively, although it sounded pretty good, just not as much to my liking as the Stack. I had decided on the Stack when the KAB showed up at my door, so I listened to it.  Once again, this is a great TT so everything tends to sound nice on it.  Then I realized the soundstage was so much better with the Stack.  I was playing the BlowUp track from 3 Blind Mice and the instruments were shifted to one side as compared to the Stack.  It really wasn't much of a competition.  The KAB is $85, the Fern & Roby $385, and the Stack Stabiliser $219.  When I first got the latter I took it out of the box and was disappointed.  I knew it weighed nothing but I just didn't see how this little thing could do anything.  You can go to their site and there's a description video of how they developed it for vibration reduction.  Shaking it is unremarkable, to say the least. It sounds like there's little rubber things in there. OK, fine. Near as I can tell, the thing works.  Sorry I don't have the mat yet to compare. It's a fairly thin one with some small little spherical absorbers underneath. It's like $85 or so.  Sometimes it's hard to believe things on appearances! Hope this helps.....

The "Gravity One"  ..... it’s construction is based upon effectively eliminating resonances. I love mine. It proves that the normal thinking about record weights/clamps are wrong

Nothing is similar to Stack in its construction thus far.

I have an OL Gravity One, which is supposed to be a damping puck--rather than a weight or reflex clamp--similar to the Stack. I trade it between a JVC TT81 w/carbon fiber on top of cork mat and Holbo w/o mat. On both it brings out the nuances. Might spring for the Stack one of these months.

A proper mat will be benefit users of Technics tts.

I'm also curious.

I have the GAE with an B.A.M. & Orth Cadenza Black. There's a 60 day return. I might give it a go soon. What cart are you running?

I recently bought their record stabilizer but it didn’t work on my tall spindle so returned it. I’m a proponent of a mat/weight concept. I have no doubt from what I’ve read that the Stack stuff is very effective and reasonably priced.

I'm a fan of the Origin Live products.
