Thorens TD 166 MkII with SME tone arm


I'm planning on upgrading my TD 166 Mk II with an SME 309, IV or V tone arm. Has any one done this? any advise? I haven't bought the tone arm yet.

Faraday Blue, if you aren't pulling my leg, I have to tell you the bad news that the 166 is not one of Thorens' finest, and not worth a high-end tonearm, or to put it more accurately, an expensive tonearm. Thorens models which could be considered of great quality include the TD160, TD125, TD124 'tables. The TD166 has a plastic inner platter, a no-no. If you want to keep it and upgrade it, then go no further than an RB250 (which would still outclass the 'table, however), as this cost would be minimal. For the price of a higher SME you could buy a whole new high-end 'table, and then put an RB250/300 on it, and have change left over. Suggestions for good 'tables abound on this website, but beware and trust your ears: never buy sound unheard.
Thanks for your response. I've owned this table for over a dozen years. I've done modest upgrades over the years to make it sound better, i.e. plumbers putty inside the plinth, a cardas golden cross phono cable and a benz micro silver cartridge. I was under the impression it was worth upgrading.
Faradayblue, I'm not saying it's not worth upgrading, I'm saying it's not worth the expense of current SMEs. A Rega RB250 will give you a great leap in performance over the Thorens arm for a fraction of the price of those SMEs you listed, with an arguably equivalent sound quality. I buy old classics all the time and tweak them to their best performance, but there is a limit beyond which it is no longer economically feasible. If you have the cash, and aren't attached to your 'table emotionally, then for the price of the arms you listed you could get quite a serious rig, or even one of the new Thorenses which come with Rega arms included, the 850 particularly getting good reviews, a true high-end 'table, and selling new for $900 including Rega arm, though you wouldn't recognize it as a Thorens. I'm not sure if you're aware, but the cheapest SME you list sells for $1550. Since you have lived with the Thorens for so long, then it is not an issue of money, but of enjoyment and quality. The Rega arms will stand up in the company of the SMEs without embarrassment sonically and give you more than you expect. If you need some good info on Thorens 'tables, the best website I've found so far is at http://www.xs4all.nl/~rabruil/td124page.html, which has a section towards the end on various Thorens 'tables and their build quality/value. Good Luck.
