I do. You can try a few mid-line varieties and see if you hear a difference. I have a very revealing system with dedicated lines, power conditioning, quality cabling and acoustic treatments. Everything matters.

Do I need isolation footers for my components if I’m already using an isolation rack with de-coupled shelves, such as the Mapleshade racks? You do. Sort of. But really, there's no such thing as isolation. What there is instead is vibration control. Most of the vibration actually comes from the component itself. Its the way that vibration is controlled that affects the sound as it gets into the music. That is why no matter what rack or shelf or whatever you use, even the floor, still and always whatever is used under - or on top of! - the component will affect the sound. For better or worse. Depending on what is used. Everything makes a difference- but not all the differences are good. Or good in the same ways. Do you "need"? No. But since this has at least the potential to be a very cost-effective improvement, its well worth the effort to try and see. |
Here is an easy exercise, to answer your question. Gather household items: rubber doorstops, protective furniture leg discs, pencil erasers, pill bottles, wooden cubes, different kinds of tape. Place them under and on top of: electronics, cables, ends of power cords, speaker cabinets. You can even use them in some combinations, together. Some will improve the sound, some will make it worse. The piece that improves what you hear in one application, might not work in a different one. This is a harmless, low cost way to experiment with tuning your system. The higher the quality of your setup, the easier it will be to hear changes. At some point you may want to make an investment in products designed for these applications. Make it fun. |
What rack are you using?? Mine. I would call it the Miller Carbon like my turntable but its mostly concrete so I just call it mine: Modular design solid concrete shelves with built-in sand beds, bolted to ABS concrete filled columns, topped with granite. Still need BDR Shelf, Cones, etc. https://www.theanalogdept.com/c_miller.htm The other rack in the middle is some generic thing I've long since forgotten. This is an old image from 2004. The steel rack btw cost about twice what it cost me to build the much better one. Here is an easy exercise, to answer your question. One of the best posts in a long time. Well done. |
My sandwiches of different density materials works fine for me ….Quartz feet, granite plates,cork plate, bamboo plate, sorbothane sheets, all that in sandwiches seems to controls the resonance and vibrations of my gear that is on my desk... One day I will try, springs, and crystals beds under the speakers also... |

I don’t think it’s possible to have enough vibration control, but it’s all system specific and experimentation is necessary. There are no magic bullets. In my own system, I use a combination of granite and Rock maple sheets, roller blocks,SR 1.0’s, vibrapucks, and Bindbreakers (made in Lithuania, from steel and bog wood). What you put on top of a component is just as what you put under it. |
not designed for isolation, primarily for side ventilation, however, what isolation does anyone think two layers of the larger size of these rubber feet provide? https://www.amazon.com/gp/product/B07PXNTT7K/ref=ppx_yo_dt_b_asin_title_o02_s01?ie=UTF8&psc=1 4 rubber feet on bottom of 2 side panels, 2nd set of 4 on top of 2 side panels, tempered black glass top supported by the top 4 feet. glass supports top component, up to 150 lbs, i.e. Heavy Amp over Tube Preamp (why I designed it for myself). Lower component isolated from component above. I think it is unique, others might like it, I will be selling it soon, editing photos now. IOW, I will be promoting the side ventilation, can description also promote isolation, or just let people think what they think? how do we post photos here? |
