Send a note to Chris Brady, he is helpful. Since Teres sells their VTA adapter with their own arm, I'll speculate it can still be bought separately. Your MMT is a good budget arm - maybe worth a try in the interim.
Teres Tonearm Help
I recently purchased a Teres 135 kit for a very reasonable sum. I sold my RM-5 and am using my AR ES-1 and Sumiko MMT with my Dynavector 10x5. I also have a Glider LO. Looking for a little help picking a Good arm to match these carts and I`m thinking of the Analog Audio MG-1. I have to stay around 1K at this point. Suggestions Please!
