On the draining of resonance.....

Jafreeman, nice system! I would not recommend putting metal cones or spikes directly on a stone surface like the one depicted under your amp. In that case, the stock rubber feet would likely perform much better. My experience is that spikes or cones work much better in the conditions similar to those shown in these images, where they are used to couple gear to a large slab of wood, which is then in turn isolated from the room. http://www.mapleshadestore.com/galleries.php. YMMV.

Wierd. That was not the link I intended. Trying again. http://www.mapleshadestore.com/galleries.php

Tnanks, KN. Maple shade makes very nice looking stands and platforms, brass, etc. and look effective. Although I would not scrap my solid maple table/stands, the granite slabs I am using have turned out to be mostly a sonic bust. I now have prototype footers on the granite surface and under the ARC mono blocks, one footer under each of the seven rubber factory feet. I also have footers underneath the Wadia player's metal pucks that receive the factory points at each corner. My footers are my design, use two natural materials, and are still under development. So far, they have taken the massive granite slabs out of the chain of transmission, imparting a new plateau of clarity, so I know they are effective. I hope to release them to the audio community as a low-cost addition, to be used in conjunction with plinths, slabs, points, factory feet, etc. From the opinions here and industry approaches offered, a general isolation rule has emerged: At least two isolation methods using a variety of materials are necessary in an audio system.

Cool, will be interested to see what you have come up with. I am big on home brew isolation solutions, and my opinions have been hard won! Lots of early attempts that were different sounding from stock, but not always better, as mentioned by someone earlier in the thread.

KN, in the Socratic tradition, your wisdom lies in not having knowledge of even one thing going forth, only to emerge with truth. I like to think so, anyway. Having little electronic knowledge, my DIY efforts have centered on the areas of room acoustics, building cables and the isolation of gear. These are product categories open for development by anyone, and it's just plain fun to achieve improvements on your own, without succumbing to the purple prose reminiscent of the Old West's traveling medicine show, where no claim is too fantastic to believe. It also helps to acquire finer new and used gear, even at reasonable cost--then the real DIY fun comes through, as you well know. Do you have some links to pics of your isolation/system?
