I'm currently browsing fleabay for a half decent turntable. I have in mind Thorens TD16x Rega planer 2/3, Dual 505. Which of these performs the best, particularly in terms of rumble from bearings. I have noticed that there are numerous upgrades available for Rega players, ruby bearings, psu upgrades etc. Are these upgrades available for the other makes too. Please advise Mike
