any good mat for a rega p9?

Herbie's "Way Excellent II" mat works wonders on my Rega P3-24. To my ears, a very noticeable improvement over the Rega felt. A great "bang for the buck" tweak, and I believe there's a trial period, so you've got nothing to loose. Good Luck, and Happy Listening.

I'm using Origin Live Performance mat on my P9 with great result.

I am also using the Herbie´s Lab Mat in my Rega P9. The sound improvement in my case was just amazing. Better details, transparency, tigher bass...and it looks really better than the origal one.

Anybody used the German Millenium Mat on a P9 before?

I am using the Living Voice Mystic Mat on my Rega P9. The improvement over the standard felt mat was immediately apparent
