Dear Halcro: ++++ " So you prefer the platter and tonearm to vibrate homogeneously?
In my system .I prefer them not to vibrate at all? " +++++
of course that we prefer not to vibrate at all but this is only in a perfect world.
The TT always vibrate/resonates and the stand alone tonearm board too bacause tehre is no way to isolate 100% of where is seated or for what is surrounded. As a fact the tonearm/cartridge are in continuous vibration way.
You said that air borne feedback does not exist on stand alone tonearm towers but you don't have any test that could prove it. I don't have on hand but exist studies that proves that every single system and especially the analog source is affected by air borne feedback.
Maybe at very high SPL we can't detect it because that high SPL but exist no doubt about. Yes, the cartridge is more sensitive to that air borne feedback.
In the other side you have to take in count that the cartridge is extremely sensitive to tiny very tiny microscopic motions that for us are non-detectable but this IMHO does not means does not exist because exist.
The ships/water example by Lewm is very good and self explained to be against stand alone tonearms towers.
The problem is that what " happen " in theory unfortunatelly in this regards can't be duplicated in our systems so we are unaware of it and unaware of any single sound degradation coming from that subject.
I know you are a wise person and there is useless to ignore something that exist and ignore it because we can't here it.
I promoted the stand alone tonearm towers years ago and still think is the best way to go till exist a better way to isolate from the TT the tonearm/cartridge unit.
In this same thread I speak very clear about what that UNIT means and why is the cartridge the King and all other links the slaves. The UNIT is not the King as it's not IMHO the tonearm.
A tonearm design goes around from the begin to satisfy the cartridge needs not the other way around. That the tonearms designs don't take that statement at 100% does not means those designs are right.
Example, today and in the past people/designers/reviewers suddenly vote for the 12" tonearms against 9"-10". IMHO the 12" makes more harm than help to the cartridge works.
A cartridge between other things moves in the grooves at random for the tonearm with suddenly direction changes where the tonearm has to be and has to has a fast response on what the cartridge is asking for, a longer tonearm respond slower than a shorter one ( everything the same. ) so the longer tonearm goes against the cartridge needs and can't fulfil those needs where a shorter one makes it in better way.
There are many other disadvantages and the " only " in theory advantage that a longer tonearm has is that the tracking error is lower but is only in theory.
In other threads we already discuss about and the real subject is that no one can hear the difference for the better because a tonearm is longer.
But as this " stupid " myth there are many in audio.
The tonearm and cartridhe form a UNIT but the tonearm is a slave of the cartridge and the real King. Just an opinion.
