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

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.

Peter - I've spoken directly with Brian Laker of SME about the mat. He said the only difference is the color. "A superior interface with vinyl" is an original advertising claim for Isodamp's use on turntable platters in general, way back when SME first started using it. I agree with your mention of the suspension towers now having viscous damping as with the 30 tables. I was not aware of that change. All the changes do bring the 20/3 closer to the 30/2. Perhaps we will see a published review directly comparing both in the future.

please, the SME 20/12 has the suspension towers having viscous damping?

rgurney,
the TAS review is very close to a comparison and they spend a lot of words comparing the two tables and how the 20 has changed to get closer to the 30.
