The only thing you can say about the Technics is that they are well made and slick looking and pretty cheap which is why people fall for them.
Americans love cheap well made garbage.
$4000 is cheap for you ? SL1200G cost $4k and it’s very expensive turntable, still not overpriced like almost everything in high-end world today, especially thos belt drive you’re using. Technics tonearms always were super high quality like EPA-100 series with ruby-ball bearings, VdH has been using them as his reference. The EPA-100 mk2 is the rarest and this arm alone cost over $3k.
You Technics experience base on $1200 SP-10 mkII drive and nothing else, i assume you know nothing about Technics. First make sure your used gear is in mint condition and works like new before you will post comments based on your memories from errr 70s/80s/90s ???
I have tried many different models of Technics turntables, tonearms and cartridges in the last 5-7 years. I have some of them right here along with many top quality turntables, right now.
I want to remind to anyone that NEUMANN cutting lathe comes with Technics Direct Drive motor SP-02. This is the motor under the platter when cutter stylus cut the lacquer disc for each record in vinyl manufacturing process. Look at the catalog posted by jpjones
If anyone made the best Direct Drive motor then Technics direct drive is one of the best ever.
