Brinkmann vs TW Acustic

SYMPOSIUM STEALTH STAND 24WX19D LIST $1400.00 SELL $700.00 8/10.Perfect for TW or any turntable best isolation at a great price.

CT0517, I only have one motor. It takes around 13-15s for the platter to come to a complete stop when I timed mine (Raven AC-1 with BN battery supply)

Thuchan ,

I would love some further explanation of how isolating the motor and turntable separately be off benefit. I am assuming motor vibrations.

Then your comment seems to fly in the face of Syntax's major complaints regarding speed accuracy or even the need to use a timeline.

There is no way vibration is action can be accomplished by a perfectly inert platform. It just isn't isolation then. Then the motor and turntable being Independant of each other would have increased wow & flutter.

Furthermore, if your experience is based on listening, then isn't isolation more important than speed stability.

This is all just conjecture, but based on your statement I don't find another path of logic.

The Symposium Ultra provides no isolation properties. It dissipates some energy at some resonant frequency, but isolates absolutely nothing.
I own an Ultra Platform and it is a nice footer, however I do not use it under my TW table as it does nothing to help isolate.

Cheers

My concern with motor on one air isolation platform and the turntable on another and perhaps a flywheel on a third is that one air platform may slightly change in height relative to the others and this would effect belt/thread level and tension which in turn would effect speed accuracy.

It is a similar argument that the proponents of a closed/rigid system use for a fixed arm mount and platter bearing so that the relationship between the two never changes, so alignment never changes.

In the SME case, the arm and platter are fixed, the motor is on a different and isolated level, presumably for vibration isolation. So perhaps SME has prioritized the importance of one over the other.
