I have threaded bearpaws from Edensound going directly into 3 inch maple platform. Tried a few alternatives but going direct was the best sound. Trial and error will give you the best performance. Get busy and let us know your results.
Using protective discs under brass footers
I'll soon be taking delivery of a new rack and half of me wants to protect the beautiful maple shelves by using brass discs under the brass footers and half of me wants to put the footers directly onto the maple shelves even though they'll indent the wood. Anyone done an A/B to see if there's an audible difference?
