Anyone use a Ringmat on a TT

I have used, on my Rega P-9 with Benz Ref silver mc, the stock felt, Audioquest sorbothane mat, and the regular (not anniversary) Ringmat. I have used the Audioquest sorbothane mat for over a decade, but now prefer the Ringmat.
The Ringmat is a tad leaner in the upper bass, but is "faster", a little crisper and a little more detailed from mids to highs than the sorbothane. Both are better than the stock felt. Overall I think the Ringmat is an improvement over stock and recommend it. with ONE condition:
I have several speakers I use on my LP system, when I hook up my big JBL L-200's (15" drivers) a howling acoustic feedback occurs around 250-300 hz or so, apparently resonating the hollow area under the Ringmat's paper and cork. I have never experienced this with any other mats, but it is just with this speaker, which plays VERY loud and forcefully.

Hi there,
Sorry, I don't go into in depth analytical postings but I use Ringmats on both my Roksan Xerxes and my Linn Sondek.
Far cleaner sound than the standard felt mats.
Tighter bass, better detail & staging.
I have never had any problems with subsonics and I use a sub and like to play loud !
I usually use a couple of small blobs of bluetack to stick the ringmat to the platter.
The Anniversary mat is supposedly better but costs a lot more.
I have tried a few other mats of heavier varieties but these usually finish up being glued to the platters of my homemade Lencos which the heavier mass seems to suit.
Hope this helps.

Ringmat was HUGE improvemtn on my Systemdek XII and (not as) HUGE improvment in my Rega 3. Seems to improve most tables- But you gotta listen & like the results

My experience is that the poorer the suspension of the table, the more beneficial the Ringmat will be. Tables that can't properly drain air-borne vibrations or lack isolation from floor-borne energy may respond positively to tweaks like the Ringmat.

The arm / cartridge tracking across a record with / without the Ringmat is kind of like someone walking across a floor that is rock solid in terms of consistent support or a floor that is "springy" due to having limited support with the supports spaced a distance apart. Obviously, one of these will be far more consistent in terms of what to expect in terms of "sure-footedness" ( tracking and vibration ) whereas the other is going to introduce variables into the equation. It is for this reason that tables that are more advanced / suffer less from microphony and smearing due to vibration induced resonances won't take too well to this type of device.

With that in mind, i would recommend avoiding the $60 - $130 expense on one of these items and investing that towards a better turntable and / or turntable installation. After all, you are talking about a piece of cardboard with a few rings of cork glued to it. I'm NOT saying that "tweaks" don't or can't work. What i am getting at is whether or not this "tweak" is really worth the money. Could you find a more effective way to combat the problems that this tries to address? Personally, I think so. Sean

PS... No weight to transport, no fancy packaging required, minimal outlay in terms of production materials, etc... Must be a helluva profit margin in something like this. No wonder the places selling it recommend it so highly.
