Here is one of the greatest audio
upgrades you will ever find for your NAD!
VIBRO-STOP Platter Mat
for NAD (and other) Turntables
If you own any type of turntable then you really need to hear what this can do for your sound!
Developed by a professional Audio Engineer with over 30 years in the business, this amazing platter-mat will enhance the quality on almost any system...! The VSPM material has been carefully tested and selected for optimal performance, and the results really show in the sonics!
PLEASE NOTE: Some eBay competitors are selling ordinary acrylic imitations of our product... Please note we are the ONLY ones with the specific materials used in our platters, and we are the ONLY ones offering measured PROOF of performance. Check our feedback and see how many clients LOVE our product! Why would you trust imitators who offer only "good looks" with no guarantee of how good it sounds?
If you want the best performance get a VSPM... Accept no substitutes!
So... Just what makes our Vibro-Stop Platter-Mat better and different from its imitators?
1) The special grade of materials, treated with our proprietary process, has unique sonic properties. It's our secret. And it only comes in black.
2) The 287mm diameter is specifically chosen to minimize the negative effect of edge-warps on the LP. We don't offer other sizes as this has been proven to be the optimal for most LPs.
3) Measured proof of performance. No one else offers this!
4) Conditional Money-back guarantee! If you don't like it we will buy it back! (UK only, see details in 'Price' section).
5) Check out the 500+ positive testimonials (feedback) showing that we deliver what we promise.

Q: What could be better than an NAD turntable for great sound quality and reproduction?
A: A NAD turntable outfitted with a Vibro-Stop Platter Mat of course!
If you have an NAD and want to get the best sound quality from it, this inexpensive add-on really performs! We confidently claim to have one of the very the best platter mats on the market, and if you look at our measurements section, we'll prove it!
Here are more testimonials from our eBay feedback:
“An excellent product , immediate and obvious improvement . Recommended !!” j***7
"Used for several days now,awesome, great, excellent, perfect, yes I like it" 6***6
"Great upgrade, I just stepped into the reference level. Thank you kindly!!!" r***e
"Very happy with the upgrade - Big improvement !" b***a
Here is what VSPM delivers:
1) Even inexperienced listeners can tell the difference. From a real testimonial:
“My wife doesn’t really know much about audio, but she readily heard and loved the difference in quality after installing your platter mat.”
2) Unlike our competitors we PROVE it is better… with measurements!
3) Saves BIG money! …. instead of spending many £1000’s on expensive rigs, VSPM gives you similar or BETTER sound quality for a fraction of the price.
4) Works really, really well with almost any model or type of turntable.
5) Radically improves the appearance of most turntables - it is surprising to see how good the VSPM makes things look.
6) Improves everything: better lows, tremendous heft, slam and impact, mids and highs, much more dynamic contrast, deeper and wider "holographic imaging", much greater retrieval of inner detail.
See here: it takes nearly any “mid-fi” turntable to a level that competes with true Audiophile decks...and it takes many Audiophile tables into the super-deck ranges!

SCIENCE, MEASUREMENTS, PROOF
To properly measure and evaluate the LP surface resonance issue, we had to custom build specialized vibration actuators and measurement systems.
(Note: Our products are developed and TESTED by a “golden-ear type” inventor with a BSEE and over 30 years in audio...)
We tested dozens of materials and sizes before finding the right mix for the VSPM... we ALSO tested many competitors' mats, including felt, leather, glass, cork, cork + ground rubber, laminated and “constrained layer” types, sorbothane, wood, acrylic, special rubber “audiophile mats” loaded with tungsten, metal mats, foamed plastic mats, and so on.
The results? The VibroStop material significantly outperformed all others.
Ed. Note: We wonder why our imitators don't publish test results! You should wonder too...
Vibro-Stop is by FAR the best-measuring Platter Mat of all those we tested. (Also the best sounding, but that's for you to hear!)
Vibro-Stop vs. Rega Felt Mat
or Rega Glass Platter
The Vibro-Stop Platter Mat clearly outperforms both the Rega Glass platter, and the Rega supplied Felt mat + Glass Platter. The green Vibro-stop line shows up to 25-30dB improvement over the Rega supplied felt mat, as well as a substantial improvement over the naked glass mat. These measurements clearly show the outstanding resonance suppression properties of the Vibro-Stop Platter Mat.
NOTE: Most turntables (Denon, Linn, NAD, Rotel, Pro-Ject, etc.) do best with a single VSPM... However, some 'tables like the Sota and Technics SL1200, need TWO of these platter-mats for best results. See our other listings for details!
Vibro-Stop vs. Technics Rubber Mat
The above graph shows the radical improvement Vibro-Stop offers over even the highly regarded Technics “audiophile version” of their heavy rubber mat, both tested on a SL1200 turntable. As seen on the graph, Vibro-Stop (in blue) provides more than +10dB of added suppression of unwanted LP surface resonances over the Technics mat (in red). When compared against regular rubber mats the improvement gets to be over +25dB !!

TECHNICAL DETAILS
Quick Overview
BETTER BY DESIGN - VERIFIED BY MEASUREMENT - AUDIBLY SUPERIOR
Here's HOW the Vibro-Stop Platter Mat WORKS
1.) The action of the stylus on the record surface creates mechanical propagation waves in the material of the LP. These waves must be quickly dissipated or they will create many time-delayed reflections and "ghost-images" which make their way back to the stylus and create resonances, muddiness and colorations.
2.) Most platter mats do a very poor job of absorbing and dissipating these resonances. These random extra vibrations of the LP surface can make it very hard for even the best stylus to track properly.
3.) The material in the Vibro-Stop Platter Mat is a special grade and thickness of thermo-plastic selected after a great deal of materials testing.
Our VSPM mat greatly reduces the unwanted vibrations and offers the stylus a much more stable playing surface.
4.) We found that there is an optimum hardness, thickness and mass that is needed: too much or too little and you lose performance. We've got the goldilocks formula dialed in: it's very near optimal, and it shows in superior measurements and audibly better results.
5.) Depending on your turntable, the VSPM can even reduce the transmission of spurious vibrations into the tone-arm! It reduces the “singing tonearm” syndrome so much that it can make even a humble little tonearm sound like something much more expensive.
6.) Most turntable platters have metallic sounding colorations from the platters themselves.... these impart a somewhat edgy and harsh midrange to the music... and the factory-supplied rubber platter mats usually add a coloration which also makes it sound dull – edgy, harsh AND muddy/dull.... not a great combination!
7.) In contrast, Vibro-Stop Platter Mat reduces almost all of these colorations, and greatly helps with nearly all platters, whether direct-drive or belt-drive platters.
8) Because many LPs have edge-warps, they can "push off " from the platter-mat surface. To help with this, at 287mm diameter, VSPM is deliberately sized to be smaller than the LP and avoid contact with most edge-warps.
Also, 287mm fits inside the raised outer ring found on some turntables. Example: most mats are too big for the Technics range, ours fits perfectly - on the great majority of turntables, Technics or other brands. Our mat system has another advantage: a milled recess for the record label. Result? LP surface sits flush on the VSPM for optimal resonance damping.
9.) Vibro-Stop Platter Mat GREATLY improves almost any turntable! It works its magic especially well with direct drive units from Technics, Sony, Yamaha, JVC and Denon, equally well with most belt-drive units including Rega, VPI or Linn-Sondek, and especially well with Garrard 301 and Lenco.
10.) Platter size: 287mm (11 3/8 inches) diameter and 3 mm thickness.
PLEASE NOTE: For Sota, Technics SL1200, Garrard 301, and Lenco we recommend using a Double Thickness VSPM (two VSPMs back to back). It makes the them magnitudes better !!
Again, this platter mat is a very, very big upgrade in sonics and usability for Audiophiles, DJ's, and even casual listeners. It makes a huge difference!
