Just to clarify for you.
We have four of the Herbie's Giant Fat Gliders under each of the ProAc D40R's.
We have four of the Herbie's Tenderfeet Extra Firm under the Verdier.
We may add a couple more Gliders and Tenderfeet as indicated and see if we can tell the difference.
We have Herbie's Way Excellent II Turntable mat on the Verdier platter.
We have Herbie's Grungebuster sheet product, cut to size, at the interface between the Granito base and the tonearm setup tower, and between the tower and the Moerch tonearm.
We have no experience with the other Herbie's products, but they should work well if our experience is any indication.
We have not and would not put any of them under Naim products.
We are glad to see you all buying American products and reporting favorably on them.
Don't hesitate to contact us if you are over this way. We can be contacted through the contact information in the profile.
If you have a turntable, try this. Just out from Analog Productions. Another great suggestion from the Vinyl Valet.
