Is there any value in adding Isolation feet to Emotiva amplifiers? I have my center on the shelf just below my amp so I am sure it transmits some vibration to the Amp.

Emotiva amps are rather hefty and heavy. Vibrations sent by a center channel (which mostly contains dialog) aren't likely to be noticed by the amps. I wouldn't bother with isolation feet. Now if the center is imparting vibrations to the surface that's supporting it then there may be some value to be had. |

I've used the brass isolation cones in the past and never heard any difference. Never tried the squishy feet though.

I have feet (spikes) under the center channel, but it's mostly for looks and to achieve the proper angle.

I've used Sorbothane feet in the past on my Directv DVR and that actually makes a huge difference. The DVR vibrates due to the spinning hard drive. You could feel it in the shelf. The sorbothane feet removes those vibrations.

I have a steel framed glass shelf that is pretty solid but I just thought since Yamaha makes a big deal about vibration I should be concerned. Maybe I should put U-571 on at reference and see if I can get close enough to touch the shelf and see lol.

Sorbothane works very well... but don't buy the ridiculously expensive specialty ones. You can get an 8-pack of 1-1/4" Sorbothane feet for $15 or so on Amazon.
Two things to note:
1) Sorbothane has a lot of plasticizers in it, so it will stain some surfaces (especially unvarnished wood and some plastics). If this is a problem, you can simply put a small wood or metal disc between the Sorbothane and your furniture.
2) Sorbothane feet come in a variety of shapes and "squishiness". You should always choose feet that are rated properly for what you intend to use them with; they're usually rated in terms of how many pounds a set of three or four are intended to support, and you want to use a given foot to support between 50% and about 80% of its rated weight. (Getting feet that are too stiff or too soft will result in less effective vibration reduction. DO NOT pick ones that are "heavier duty" than what you need; they will not work as well.)
In general, amps and most other electronics are not especially sensitive to vibration.

Keith good stuff to know, I didnt imagine it would be all that complicated. I am glad that I asked before just buying them based on their dimensions.

I use the carpenter type cookies, to prevent my gear from sliding, and I use them under my center for give them some height.
They're cheep and come in a pack our fours, for less than 15 bucks I think.
Good luck
Dan

I've also used the discs you put under furniture legs to keep from scratching the floor between the sorbothane and furniture. Easily bought at Home Depot, Lowes, or your local HW store. |
