I had the Herbie's mat and now have an Acryl-It on my 1Xpression. The Acryl-It was a good bit better in my system. Definitely worth the few extra dollars than the Herbie's mat.
The Herbie's mat was no slouch though. The Acryl-It just does everything the Herbie's mat did a touch better. The Herbie's mat and Acryl-It platter together didn't go very well. Everything was over damped.
I'd get rid of the cartridge when possible. The OM series carts are outdated. They were designed for older tonearms, and today's tonearms either have more or less mass (can't remember which). The new Ortofons will be a worthy upgrade, as will other carts.
