Micro Seiki MA707 vs CF-1

I see photos of these two tonearms, and they appear to be identical. In both cases the arm tube can be black in color, which I assume means that it is made of carbon fiber, and has markings at regular intervals from pivot to stylus. However, sometimes the armtube has a sliding weight on it, sometimes not. I understand from my reading on the web that the graduations on the arm tube along with the sliding weight are used to adjust tonearm effective mass. So, two questions, really: What are differences between the two arms? If I see an arm tube that is black and has the graduated markings on it but no sliding weight, is it likely that the arm is incomplete? And BTW, does the MA707 or the CF-1 offer any kind of repeatable VTA adjustment, on the fly or otherwise? Thanks.

Thanks, Clio09. That's about what I had come to believe from seeing photos on-line. So I gather that the major if not the only difference between the two is the carbon fiber arm tube on the CF-1. If I see an "MA707" with a black arm tube, I then assume that it's made of metal, just painted black. Correct?

As an aside, you say you replaced your 707 with a 505. Do you think that the 505 is a better all around tonearm? I've got a 505 MkIII, which is quite nifty, but the MkIII version no longer has the VTA "on the fly" feature. It IS however set up so that changing the VTA is very easily done.

Thanks, Clio09. If you subtract the 707 from the 505, you have the 202. Until I saw that M-S 99V turntable for sale here a few weeks ago, I did not know that the 202 tonearm existed. My gut instinct was that the 202 could not be as good as the 505 or 707, since, after all, the model number is lower. OTOH, they sold it with one of their finest ever belt-drive turntables. So, what's up with the 202? Don't worry, I am very pleased with the 505 and plan to keep it. I'd just like to learn more about M-S products. Still would like to find that special wrench for the 505 mounting bolt, though.
