Has anyone experimented with replacing either the feet and/or the clamp on the Classic? Mine arrived late today and I'm extremely pleased with it (using a Glider S Hi output), but wonder what inexpensive upgrades are available. The stock clamp is adequate, but I'm thinking of replacing it with one from TT Weights. They also sell feet. But I'm hoping my large Audio Points will fit. I'd be interested in any other tweaks that have been successful.
