LS50 and Big Fat Dots

I have a pair of LS50s placed at the ends of a credenza and don't have room to place them on stands.

I have been using those time rubber feet that came with the speakers bur was wondering if using something like Herbies Big Fat Dots would make any perceptible improvement in the sound.

Actually they are sound pretty good powered by a NAD D7050. The credenza is very sturdy made of real wood, but when I put my hand on it I still sense some vibrations. Perhaps this vibration may be muddied the sound in some way. I'm frankly not sure because I'm not sure what would be the best performance of the speakers and amplification. What kind of improvement should I expect it it does work?

On a final note, I thought about the big fat dots because they seem to be very non-descript and will not affect the decor of the living room.

Does anyone has any experience with this product and can give some information?

I don't think you can predict how different footers will affect the sound of a
speaker.
Herbie's dots are made for a variety of
applications, particularly so cabinet resonances don't transfer to speaker
stands.

Auralex pads are made primarily for setting mini-monitors on large flat
surfaces, isolating them completely from the surface below via a specific
density of foam, and have a front dam to block soundwaves from surface
bounce on a table top.

The vendor I linked to also has a 30-day return policy. You can also get them
at your ubiquitously local Guitar Center.

For an interesting take on component isolation (including speaker supports), go to the Barry Diament Audio site, under "Articles", then "Vibration control for better performance". Barry is a proponent of the "roller bearing" theory.

I don't know anyone in Audio whose advice I regard more than Mr. Herbie .

The issue I have with roller bearings is their rather poor vertical isolation performance however I am a big fan of roller bearings on top of a good vertical isolator such as springs.

Exactly Geoffkait. In Barry's writings he describes the roller bearing as an isolator in the horizontal/lateral plane, and a coupler in the vertical. He makes the argument that most vibration travels horizontally, the waves moving across the floor, just as the movement of the ground in an Earthquake is horizontal/lateral. He recommends an air bearing for vertical isolation, something as cheap as an under-inflated bike tire inner tube under a piece of plywood up to the old Townshend Seismic Sink. Townshend himself now sells a spring isolator (the Seismic Pod) which he claims isolates in both planes.
