Micro SX-8000 II or SZ-1

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...

I'm flattered pictures of my Micro Seiki RX-5000 system ended up on this thread!

I'm not nearly mathematical enough to place a percentage on the improvement I hear with the HS-80 inserted, but it is noticeable, particulalry in the nature of the lower octaves. Also, I am keenly aware its position in my system is severely compromised, and I am working on a rearrangement of my gear to allow the in-line layout of the motor, platter and HS-80. If accomplished, I will post more pics.

I'll reiterate that I have not had as much fun listening to vinyl in my entire life than with this Micro system. Yes, I could dream about an SX-8000 series 'table, but I'm not itching for one. I'm extremely happy with the RX-5000.

Thuchan, I'm still thinking about it, but I think Quiddity's earlier point was that the high speed of the flywheel in the SZ-1 motor (and therefore, probably similarly, the HS-80) offers more theoretical inertia than a (second) heavy platter does if the second heavy platter is spinning at 33.3rpm. I cannot deny that the second SX 8000 would be able to mount 4 tonearms, but then again, so could an SX1500, SX5000, or SX8000 without the "II." I don't know where the 30% number comes from or how one would calculate it. Personally, I've never been able to compare a table to another and come up with a 'percentage improvement'. Best of luck in your quest.

I'd like to confirm T-Bone's opinion.

Two sx8000s chained together would be about 1/10th as effective as the high inertia motor assembly of the SZ-1, from the point of view of inertia alone.

The two platter solution would however result in far less belt creep. There is no solution for this dilemma within the compliant belt drive paradigm.

Good! You answers make me rethinking the whole approach and maybe returning to the HS-80 solution.
The percentage thing is just to give a clue via distance what it could be about, it is personal and vague.
I myself had the opportunity to have the SX 8000 II as well as the RX 5000 in my chain, the latter for a very short time because it was promised to go to a friend.

As the RX 5000 is an excellent big Micro and even better than most of its modern copies the air bearing concept brings a bit more smoothness and brilliance in the picture - in my opinion.
