I agree about avoiding using cones etc. If your Neuance shelf is sitting on a rigid welded steel rack, and you support the shelf on upturned spikes, then there is no real need for fancy footers and most will just impart their own sound as you say Misskuma. I still find the upturned spikes under the new Neuance shelves to be beneficial. I know Ken is trying to meet a customer need to have a less industrial look, and so is trying to avoid the rack and spikes being so important, but if you can, I urge you to try upturned spikes under the shelf. The last AB I did with (what I think is) his latest shelf, between using vinyl bumpers and using spikes was a no contest in favour of the spikes.
