Brinkmann vs TW Acustic

Was wondering how these two German manufacturers compare.
Bardo vs Raven One
Oasis vs Raven GT
LaGrange vs Raven AC
Is there a unique sound signature that goes up with the range? Which is a better value? (i.e. maybe the Oasis is better than the Raven AC)
Have heard both in show conditions, but could not pin-point their contribution to the end result as the rest of the system was unfamiliar as well.

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.

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.

Dgad,

yes, you`re right it blocks motor vibrations if implemented properly.
This no argument against speed control or not using the Timeline. It is an additional measurement improving the sound. Believe me I worked and experimented a lot on vibration issues. Also the original air dampened Micro base for my SX 8000 II comprises two separated top-bases , one for the motor, one for the drive. To put the exact pressure on the belt or string you can move them closer by a very smart button device on the side of the heavy base. A very elegant and effective solution!

Symposium works wonderful in my system i have concrete over parquet floors with cinder block walls on a 200lbs Rix Rax. Tally Ho!!

Dear Peterayer,
you concern is absolutely okay. You need to level all three platforms in a way that they meet exactely the height you need. I do this with Copulare Coral lifters under the platforms by which you can adjust pretty fine turning the lifter. Just try it - you will not believe what you heard before!

In the SME case you described everything is done well.
