Difference between SME 3009 VS. RB 300?


Anyone with the experience for both arms,assuming both are mounted on the same TT. Yes the SME is old,but curious on how it measures up against the RB300?

Please make a note that you can try out an AudioQuest PT9 arm that sort-of combines quality of both and in the same price range + very user friendly. Will be a great match to any inexpencive turntable such as Thorens TD160, Well-Tempered. For more expencive precision-crafted decks I would suggest RB300 or even RB250 that goes in standard package with lots of great decks such as Basis, Clearaudio, Michell and even LP12.
Soon I will have a 3009 arm mounted on one of my TD 160's and I have a Rega 25 with RB300 arm and the incogito wiring upgrade, heavyweight, and VTA riser kit. I intend to do some extensive comparisions between the P25, modified TD160, the stock TD 160 and the old relible AR XA and see which decade's system rules.
I confirm Mara's point above. I had a 160/3009, eons ago, and was sonically happy with the combo.
Goroi: There were different versions of the 3009 (the later/lighter versions will limit the types of cartridges that can be matched up). Because of this I would not go beyond a 3009II (non-improved version) if considering this arm (from there on the mass was reduced). The 3009R has a fixed headshell and is a bit more solid, though I find the azimuth adjustment on the 3009II (non-improved) to come in handy.

I am also curious about the Rega arms (the modded 250 seems to be the most popular) and only ended up with the 3009II as it was included with my current deck @ a price that I could not pass up ($199 for a TD125 MkII/SME 3009II combo).

What I would really like (down the road) is an arm that has adjustable VTA, on the fly (this would make me a happy camper). I wonder if such a mod is available for the Rega arms?
