Thank You jafant
It's been a long journey with trails and errors of trying to use different damping materials , wiring gauge size and configuration and scariest of all stripping the threaded inserts out of the MDF ( don't use a drill ) . But upgrading the components on the XO boards has been a great success . While I am waiting for Clarity to release their 630v Purity caps to finish the upgrades I have started to think about moving the boards out of the cabinet .
