How to upgrade my thorens 166? Is the SME 3012 better than the RB 300?


I need help on how can I can upgrade my turntable? Somebody is selling me an SME 3012 tonearm and a RB300. Which should I get? What kind of upgrade can I do with both arms and which tonearm will sound better before the upgrade? After the upgrade?


I have both the SME 3012 and the Rega RB300 in daily operation. The SME is beautiful and has very low tracking error due to its length, but the RB300 is a much more modern and precise sounding arm. It has lower mass and is much stiffer, giving better bass, dynamics and micro-detailing. The RB300 can be upgraded through various paths, such as internal cabling and mechanical changes to the counterweight. Good luck!

There you find real tweaks for the SME 3009/3012 tonearms. Please feel free to ask me for questions.

Here is the link for the price list and the mounting procedure for the bronze knife edge bearing.
