I've used a number of vintage Thorens tables over the years.I currently own a TD 166 MK II.I've tried Ortofon OM-30 Super,LM-20,X5-MC and 2M Blue cartridges with very good to excellent results.I love the Blue and the X5-MC is my favorite(also the most expensive!).I've always used Ortofons on my Dual and Thorens tables as they often were supplied with the tables and the arms and tables were often designed and tested with Ortofon cartridges.
Good Cartridge Match for a Thorens TD166 Mk II
no upgrades done to this table and am now using a Grado Blue...lots of sibilance to my ears,wondering if this is normal and due to age of 'table or cartridge itself.Original tonearm and no real need to change it.
