Thorens TD 520
Thorens TD 520S
Thorens TD 521
(1985 -1999)

Large Thorens masterpiece based on the earlier TD 320 but adapted for the use of long tonearms, originally Thorens' own TP90L. A bestseller in Japan, often flanked with one of the Japan-only SME 3012 variants. Both versions have a stroboscope and can spin at 78rpm.
The model TD 520S has a heavier 9kg platter made of brass, an acryl tonearm base, reinforced motor and chassis feathering and was fitted stock with an SME 312 - that's the Professional version. The TD 521 is a TD 520S without tonearm or automatic end stop.

LP replay on such a luxurious machine borders on the sublime, really. But then, there also are other near-perfect record players : Sony, Yamaha, Luxman, Micro-Seiki, Technics, Denon or Kenwood !
