Best Tonearm for Thorens TD-124.

A well reconditioned 124 is a great table deserving of whatever top end arm one takes a fancy to. I don't think it favors, or is synergistic with any particular arm.  My local dealer, who recommends this table for some really high end systems, likes the top end Ortofon arms.  This makes for a quite reasonably priced combination.  If this does not seem like a high end combination, consider that he sells more Koetsu Rosewood Platinum cartridges than any other cartridge.

Ortofon tonearms made by Jelco in Japan

The TA series are contract manufactured by Jelco. I believe that the AS and RS tonearms are still manufactured by Ortofon in Nakskov, Denmark.

I remember interview with Leif Johannsen and he said Jelco is the manufacturer of the Ortofon tonearms, they are definitely better than Jelco own design (and more expensive), no doubt. Here is the latest factory tour and there is no tonearm manufacturing department in Denmark. Correct me if i'm wrong, but i think all Ortofon tonearms made in Japan. 

It is a matter of aesthetics. A TD 124 has to have an old SME on it. It would not be right with any other tonearm. The gods of audio history will strike you dead if you put anything else on it.
