Best Footers for DAC?

Sorbothane seems like SUCH a good idea. But sounds pretty terrible, usually. Of course that’s just my opinion. If someone gets good results with Sorbothane or say lead, more power to them! There might be somewhere Sorbothane sounds good but I never found one. In fact I believe Sorbothane is the Poster Child for Expectation Bias. Like the metal lead. It’s a case of it looks like a duck, it acts like a duck, but it’s not a duck. Not all Viscoelastic materials are created equal. The trick is to find a good one and a place that works, that doesn’t choke the sound and make it weird. For headphones and such Marigo VTS Dots (constrained layer dampers) are the cat’s meow. And they’ve been around almost as long as chunky peanut butter. For transformers, capacitors and printed circuit boards, etc. I use Marigo VTS Dots and or cork and constrained layer dampers. Disclaimer - I sell a constrained layer damper and pure natural cork for such purposes. Unfortunately I cannot reveal the particular viscoelastic material I use in my product.

The effectiveness of cones in terms of SQ is primarily a function of the hardness of the material. That is why DH (Diamond Hardness) Cones sound better than brass, carbon fiber, aluminum, even better than hardened steel cones, which are all considerably lower on the Moh scale of hardness than the Space Age ceramic DH Cones. Having said that, the effectiveness of cones is also a function of the shape of the cone. Which is why Super DH Cones sound noticeably better than Jumbo DH Cones. Both are essentially the same size and weight, but the Supers have a more ballistic shape. 🚀 Is it cheating to cryogenically treat the cones? You decide. Yes, you want to drain vibration from component but you also want to decouple the component from seismic vibration. So BOTH techniques are required for best results.

Someone hasn’t been paying attention. The reason blind tests don’t mean anything WHEN THE RESULTS ARE NEGATIVE is because negative results can result from mistakes by the test conductor, mistakes in the system used for the test, and other reasons. POSITIVE RESULTS, on the other hand, tend to support the hypothesis under test, even if there were mistakes or errors in the test. You can ignore a single blind test if the results are negative. Follow? The other part of the puzzle is that when the differences are subtle or small it can be quite difficult if not impossible to correctly identify the better device. That’s the scam that Randy was running. And that you apparently go along with.

That’s part of the whole blind test scam. Nobody can pass a blind test 10 times in a row. Give me a break! That’s the beauty of it. That’s why The Amazing Randi never had to pay out a million dollars for any test, ever, not even the blind tests of controversial audiophile thingamabobs like the Intelligent Chip. No one can pass a blind tests 10 times without making a mistake - especially when the test is controlled by The Amazing Randi and his staff of pseudo skeptics. Hel-loo! 😛

Controlled blind tests are analogous to the drowning chair used to determine if a woman was a witch in Salem, Massachusetts. If she drowned she wasn’t a witch. A real witch would have prevented her own death. Duh!

Hey, let’s ask NASA. 🚀

The reason the curved surface is preferred is because the roller bearing will then be capable of isolating the component in two additional rotational directions - ROCK and ROLL. I.e., rotation around the 2 non vertical axes. Obviously, the curved surface also prevents the component from “wandering.” Isolation can be defined as the *ease of motion* in a particular direction. Either curved or flat surfaces provide isolation in the twist direction as well as the horizontal plane. The TWIST direction is the rotational direction around the vertical axis. The only one that’s missing is vertical. That’s where the springs come in. The reason ALL six directions of motion are important is because the Earth surface moves like a carpet being shaken, like a wave. So the entire house is shaking in all 6 directions! This is not rocket science, folks! 🚀

Ceramic plates are too flat. The component will slide right off the roller bearings. Besides plates won’t provide rotational Isolation Before anyone hurts himself buy the real thing. Saves a lot of hand wringing and tears.
