The JMW 10-3D and the JMW 10-3DR are identical arms with the exception of the gloss finish (more expensive to finish) and the Nordost Reference wire. Owners of the JMW 10-3D can have their arm upgraded to the Nordost Reference at the factory and it will have the same performance.

The JMW 12-3D and JMW-3DR have the same design parameters but differ in both construction and the internal wiring (Discovery vs Nordost Reference). Owners of the JMW 12-3D can upgrade the internal wiring for increased performance, but it will not be a direct equal to the 12-3DR and that is why the 12-3DR as listed as a standalone option for purchase.

I extend my apology to all or my misinterpreting the construction of the JMW 10-3DR arm in my prior post here.
Maybe, in the future, VPI will consider offering the 10 inch 3D version of the JMW arm "with" the carbon fiber wrap as an option instead of the glossy paint, which may not be as visually appealing, but offer the additional performance as described by Harry in a prior post here last year with the JMW 3D 12 R.

PS. I posted this photo of my JMW 12 3DR arm here last year with carbon fiber wrap. Not glossy but performs very well. If the carbon fiber wrap is cheaper than the glossy paint finish, it could be a no brainer.

The glossy finish is more expensive that the standard matte finish because it more labor intensive to finish after the 3D printing is completed. The carbon wrapped 12-3DR arms are more complex and expensive to manufacture than both the matte and glossy arms.

My guess as to why VPI does not manufacture a carbon wrapped JMW 10-3DR arm is that the extra stiffness and damping offered by the carbon wrap is not required on a 10 inch arm.

Brf,

Thank you for lifting the fog, as always.

As always Brf is spot in with his analysis. The 12" arm need more stiffness added the 10" does not. We could hear no difference wrapping the 10" arm but definitely heard the difference in the 12" arm.

So Mat just said this,,Is there wrap or not ???((((( Hey all, I'm still in Thailand so this will be a quick one. The Carbon fiber finish is only an aesthetic visual finish. It doesn't being any sonic improvement (at least none we have found). The reason we used it was to distinguish between a standard and reference tonearm (the wire, Nordost wire). When we first started working with Nordost on this our 3D finishing was limited. The wrap/carbon look was one if the visual options and we rolled with it. There is no real carbon fiber on it. That's because we have found that carbon fiber doesn't sound very good. Ill post more when I'm home on a computer ☺))))
