SME 20/12 with V 12 VS Sme 30/2

So, can the 20Mk2 be upgraded to 20Mk3?

Gordon - No, it cannot. The chassis, subchassis, and platter are different weights and thicknesses. You would be paying basically for most of the Mk3 without getting the whole table. SME does not make 'upgradable' products. You can only do that by buying a different model.

The TAS review of the 20/3 also mentions an improvement from the new black platter mat material and some differences in the suspension towers and main bearing improvement. I also had thought it was just a thicker platter and chassis, but there is more to the 20/3 than that. My sense is that it is considerably closer in performance to the 30 now, but at $14,000 it is MUCH less expensive. It is probably, THE value in the SME line. I would like to hear it.

The SME platter surface, Isodamp, is not new, just a different color. The manufacturer no longer makes the 'mustard' color used previously. Charcoal black is now SME's standard color, otherwise it is the same.
In comparing the 20/2 with the 20/3, the following can be noted:
1. The bearing's central damper has been improved, now more in line with the Model 30
2. the oil bath has been improved.
3. Weight went from 18.2 kg to 28.6kg - thicker chassis and subchassis; platter heavier and larger(from 4.6kg to 6.5kg and from 300mm to 312mm. (The Model 30 platter is 330mm in comparison).

SME wanted to narrow, not close, the gap between the 20 and 30 tables without eclipsing the value of the latter. The increased mass of the 20/3 provides much of that improvement.

I hope this clarifies the changes.

Rgurney,

I had thought the same thing about the new mat - that color was the only difference. However in the latest TAS review of the 20/3, Seydor states "...and the new mat is claimed to make for a superior interface with vinyl." That's the reason I wrote what I did. I certainly don't know and perhaps I'm misinterpreting the statement in the review. He goes on to mention that the suspension towers now include viscous damping as in the 30 where the 20/2 did not have that.

It certainly seems to come closer to the 30 at a considerably lower price.
