Weak points of the 1200G are tonearm, bearing and power supply. All can be upgraded here - http://www.soundhifi.com/sl1200/Timestep%20Technics%20EVOke%20%20SL-1200GAE%202018.htm
Same old BS.
Some companies are always happy to sell something for astronomical prices, but Technics completely rebuilt their production line a long time ago when the GAE was introduced. Companies that offered an upgrade for an old $400 Technics SL1200 series continue to sell same BS for brand new "G" series.
Technics is not REGA, Pro-Ject or Linn, for those companies buyers are a slave of constant upgrade.
There is nothing weak in Technics SL1200 G and tonearm is excellent, any better tonearm will cost more than the entire turntable!
In fact Technics tonearms are the best in the world, for those who don’t know I’d like to remind about EPA-100 mkII which was Technics top of the line tonearm and today it will be better than so many overpriced high-end toneamrs.
So it’s obvious that for better tonearm one needs a SP-10R (not SL1200G).
I’d like to admit that so many audiophile never paid attention to Technics products, they noticed Technics AFTER Mr. Fremer reviewed it when Technics returned to business with new turntables. Mr. Fremer actually compared Technics (without any mods) to one of his most expensive turntable, soundfiles were uploaded for everyone.
British companies will always push those ugly SME tonearms "as an upgrade" for everything, but you should really understand what is Technics and what is SME.
