Why Are Used Technics 1200/1210 MK2 Still So Expensive Compared to GR/GR2?

The question was whether the G series is any better than the older look alike series. No one said the older TTs were bad or deficient in any way that an average user would complain about. I would bet in fact that Technics sold more of those SL1200s and all its variants than any other company sold any other DD TT. That is definite proof of success. Now comes the G series that are better in most ways.

The G series have an entirely new coreless motor with better electronics to control it, a better damped platter, and a stiffer chassis, compared to the earlier SL1200 based TTs. The tonearms are also probably upgraded. KAB is a great company that offers worthwhile accessories, but such bits will not bridge the gap between the older TT s and the G series. However if the criterion is whether you can buy a wood surround for your Technics, then all bets are off.

In my opinion, the G series turntables are far superior to the non-G older turntables, so there is no earthly reason why they should sell at a premium compared to a G series, even assuming what you say is true.
