Herbie's Mini Grunge Buster

I use it with my 31.5 and it sounded and works much better than the CD Blacklite mat. You can't beat the price.

Markd51, I'll be curious to see how grunge buster mat works for you.
Could you post an update once you try it, please? Thanks.

BTW, I use the Hal-O tube dampers and they do work. I also tried the mini isocups with my preamp and it is an improvement enough that I kept them. However, the Tenderfoot feet under my ARC CD3 MkII cd player did not do much on my current component stand, so I sent them back. But I do know people who found Tenderfoot feet to improve the sound of their cd players. I guess this particular cd player plus the fact that it's sitting on the SolidSteel 5.4 component stand, did not benefit from the Tenderfeet.
But with 90 days trial period, you basically can't go wrong with anything from Herbie's.

I almost ordered them but was too lazy (my bad). I'd also be interested in your impressions if you have the time to post a follow-up.

Mark, any word on the grungebuster mat?

As a side note, there is something I wanted to mention....
As I said, I tried the Tenderfoot feet with booster blocks and on the component stand I have, they have not done much so I decided to send them back. Went to the post office, packed them up and send them Priority Mail. A thought of insuring the package never crossed my mind, since I have never had any problems with Priority Mail being delivered.
Anyway, a week goes by, I e-mail Steve and he states he doesn't have the package yet. It's very strange, since PM is ususally 2-3 days. But, despite the fact that he did not receive the package yet, he refunded my money anyway. How many other companies will do that for you?
This is what I call customer service!!!
