Micro SX-8000 II or SZ-1

FM Login, I am very happy with the bass reproduction by the SS-design provided by the Classè Omegas, the Stealth Dream and the Wilson LS (not to mention the 1812). It produces a very warm but stable sound. If you have the chance drop in and you might change your opinion quickly. I mean - if you not preconditioned and belonging to a church of SS-design refusers. Nevertheless there is always room for improvement.

No matter if you use the RX-5000 or SX-8000 II- the advantage of a proper aligned flywheel in opposite position to the motor drive is in the fact that the bearing will be free of horizontal force.
This will minimize bearing noise to the lowest possible - in any bearing.
The result in sonic terms will be increase low level detail, ambience and dynamic transient resolution.
Important factor is, to bring the string/belt tension to equal level (as close as possible) on both - flywheel and motor.
So - the advantage has nothing to do with bearing type - its a simple force vector model of two forces eliminating each other.

How did you resolve the ringing gunmetal platters? The only solution I know is either a damping mat - which can work well, or applying a damping material inside the platter - which would concern me from a perspective of rotational balance.

My personal experience reflects Dertonarm's statement: with my HS-80 flywheel in place (and now in a line with equal tension on the threads), ambience and transients--already wonderful--has improved. So, my ears disagree with Fm login's statement that the HS-80 has no benefit on Micro turntables. But, that's just me!

Thuchan, I am not preconditioned by anything and partially by any “church”. I based my judgment upon my experience, it well known.

Dertonarm, I am sorry but you are wrong. There is no such a thing as “proper aligned flywheel in opposite position” and there is not such a thing as “free of horizontal force”. The situation when the horizontal bearing is free from any force is the worse situation as the microscopic bearing beatings become the subject of belt slipping or “wind blowing”. The best configuration in belt drive is the situation what the platter with it’s microscopic horizontal bearing beatings is biased by a small belt force.

Here is no minimization of bearing noise if you remove the “belt bias”. You might accustom to light plastic TT but in case of Micro the belt bias is absolutely negligible coals to the platter momentum. If you once try to hold the 8000 platter then you would not daydream about its impact by a few milligrams of belt tension.

Also, Dertonarm , your comment about the result in sonic terms: “increase low level detail, ambience and dynamic transient resolution” is a celebration of typical audio BS. I can give you $10.000 if you will be able to increase the low level detail, ambience and dynamic transient resolution with any of my Micros by applying the flywheel. Now, how you are you willing to bet? How about to put your actions behind your mouth?
