>>"if the suspension[strings]isn't put into motion, it's no more than an elaborate coupler..."

Rollers too I might add...

Maybe now would be a good time to ask a couple of questions...

ONE: In IYO, how is horizontal isolation benificial?

Two: Can you dispute any of the following?

Roller balls do not dissipate vertical vibrational energy by rolling.

Roller balls are fully coupled while rolling (so long as they maintain traction with both surfaces).

Airborn resonances cannot overcome the static friction of a roller ball (much less with the added weight of a component).

Now also, I would like concede...

A component on rollers sounds better when it is allowed maximum freedom of movement in every direction.

I agree...I do not however agree that this is because of horizontal isolation; but rather balanced coupling.

Given that the surface is level; it is at THAT POINT, that the weight of the unit (against all opposing forces, such as the weight of a cord etc...) has been perfectly, and evenly distributed to each individual coupler(roller). That is to say; perfect balance has been achieved.

This, IMO is a pos effect, which some are contributing to 'horizontal isolation'. IMO, horizontal isolation has no benifit w/ relation to conductive, or airborne resonances.

...prove me wrong?
