Micro SX-8000 II or SZ-1

I have read that many consider the RX-5000 superior to the SX-5000. One would think the reverse to be true but I have not the pleasure of hearing either turntable. Bob

T_bone, Are those Goto transducers in the photos? I heard a complete Goto system locally in northern Virginia, driven by Kegon plus two other amplifiers and using Goto preamp and electronic crossover. And I was underwhelmed. Good but no goose pimples. Sorry for the OT comment.

I have always been intrigued by the HS-80. I believe the recommended way to set it up is so that it is directly opposite the motor. In this way the forces on the platter due the belt should cancel each other out and there should be minimum force, and thus noise, on the platter bearing.

The disadvantage, as I see it, is that you have greatly reduced the contact area of the belt with the platter. With a thread the contact area with the platter is already very small and with the HS-80 it is further reduced.

The "HS-80 MS" illustration avoids this but does not minimize the forces on the platter bearing.

It is an interesting choice of trade-offs. Set up would be critical. There are variety of formulas for pulleys, belts, contact area, wrap angle, coefficients of friction, and so forth but they were a bit overwhelming to me.

Syntax, thanks for pointing out the 'local' photos. Should have remembered that system.

Lewm, the photos appear to be the reviews of items which different people have brought into the system. The top photo is a set of Ale Acoustic compression supertweeters. About a quarter of the way down there are some Goto supertweeters. I didn't see any other Goto stuff (the super big horns near the bottom are DIY efforts, as are a bunch of the brass supertweeters).

I am considering now buying a second SX 8000 II because it should be the best solution for the inertia function. Means: the RY-5500 II motor unit drives the first SX-8000II, and the SX-8000 II drives the other SX-8000 II as shown in the system of Syntax on the two RX-5000. Based on the platter if it is 1:1 (same size) the speed should be no problem and the SX-8000's platter (or 1500, 5000) is heavier then the HS-80's small plate -this should lead to a more stable and wider sound stage. Also another four tonearms could be mounted on the second SX 8000 II. The first SX-8000 II absorbs variations from the motor then driving the second SX-8000 II. Sound will have an 30% improvement in comparison to the one set SX-8000II + HS-80.
Syntax, is that true, can you prove those assumptions?

Regarding the question what is the difference in sound quality between the air-bearing and non air bearing big Micros some people and me too think that it is an improvement of around 15-20%.

A realistic price for a SX-8000 II in a very good condition is around 25.000 US$. But I have seen offers of 40.000 US$ too, just recently. Everyone has to decide on paying such an amount...
