Herbie's mat with NAD 533

My NAD 533 with Goldring Elektra (with new Goldring stylus) is begging for a "tweak." Will the Herbie's "Way Excellent II" mat offer an improvement over the stock felt mat ? If so, what thickness for the Herbie's.....2 mm. or 3 mm. ? My stock felt mat is about 2.5 mm thick.
Gadfly.......Thanks for the corrected link. Looks cool.
A question for all who may know......From whom should I buy the glass platter ? Audio Advisor sells one (10 mm. thick, 3.7 lbs.) for $69, and there's an "official Rega glass platter" listed on E-bay (salt lake audio) for $79. Does anyone know if these are the same ?
Rega doesn't allow much in the way of discounts so call any Rega dealer and ask. The Sound Organisation in TX is their US distributor -- they should be able to point you to a local dealer.
Hi Ekobesky............Well, I got the new Rega 10 mm., 3.7 lbs. glass platter today, FedEx'd from Audio Advisor, with a new Rega 2 mm. felt mat. I immediately compared one of my "reference recordings," Sonny Rollins' "Way Out West," first using my MDF platter, and then switching to the glass.
Holy Cow !!!! I'm not sure of the correct "audiophile terms," but the improvement in the sound of the music with the glass platter was pretty amazing !! I will slowly work my way through various records and keep on comparing. But, if my first impressions are any indication of the satisfaction ahead, I made a wise choice. Thanks so much for your "step-wise" recommendation.

I'll soon experiment with the cork discs directly on the glass, replacing the felt mat, and I'll see what happens. But, it seems as if glass is the way to go. Which makes sense, since I switched from solid state (Arcam) to "glass" (Rogue Audio tubes) a while ago. Glass tubes, glass platter.....neat stuf. I'll keep you posted.

Happy Listening, my friends !!!!!
Glad it worked out for you. I owned a P2 years ago and it was a big jump when I replaced the MDF platter with glass.
