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?

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.
But most vibrations aren't in the horizontal direction. Townshend and I both built Isolators that isolated in all six directions. There are three rotational directions. Technically the roller bearings don't isolate in the horizontal only the rotational directions, you know, given the cup is curved. If there is motion it must be rotational not horizontal.
For turntables ease of motion (isolation) in the rotational direction around the vertical axis (twist) one obtains with roller bearings is not good for turntable performance since the platter rotates in that direction. For turntables it's actually best to disengage isolation in the twist direction and keep the support frame stable/stationary. For turntables one should apply isolation in the vertical direction and the horizontal plane and two rotational direction. But not in the twist direction.
The Earth crust motion actually produces waves on the surface of the Earth with horizontal, vertical and rotational forces. So the house is actually moving like a small boat on the ocean with a wave passing under it.
Let me ask you a serious question for a second, Mapman. Have you been watching a lot of Beavis and Butthead videos recently?
I very much like Sorbothane running shoe insoles. But for audio not so much. In fact, I'd say Sorbothane ranks right up there with lead as being a material foisted on unsuspecting naive audiophiles as supposedly good for sound.
"The theory of a spike being a mechanical diode (allowing vibrations from the speaker enclosure to travel down the spike, but not vibrations to travel up it) has been proven to be untrue."

Really? Since when? This is huge, Jerry, huge! ;-)
Nothing personal, just expressing my opinion. Which actually supports the idea that spikes and cones are acting like diodes.
Spikes are not mechanical diodes unless they are conical in shape. Cones are mechanical diodes as are spikes that look like cones. That's why when you flip the cones upside down - with points up - the system sounds worse. Hel-loo!
