I had one of the earlier (early 1980's) Linn Sondek TT's with the Linn basic tonearm and Linn basic cartridge.
It was hooked up to basic Naim electronics which were connected to Linn Kan speakers.
The performance of the Sondek wasn't very reliable and consistent i.e. some days it would sound quite good other days it would sound not good at all ! It's performance changed like the UK seasonal weather ! I would never know on any day how it would sound until I started playing a record (I didn't have many LPs back then so played some of them very often where I could easily hear the differences).
Never exactly understood why this was so....could only assume it was down to changes in internal room temperature and humidity throughout the year as all the other variables were constant !
