An update:
The new SOTA belt came in.
I know I had replaced it once before years ago, but this one is quite different. Much narrower in width and quite a bit shorter. Whatever; it works very well. The old belt took a number of seconds to reach speed- due to slippage I am sure. The new one pops right up to speed in about two seconds or so.
The new AT ART9xi cartridge has been installed. Incredible improvement there as well. I had installed a new stylus into the AQ B200 a few years ago, but this new AT cartridge is lightyears ahead in all respects. Considering it will improve over a number of hours still, I am quite shocked with the superior sound quality right out of the box.
All I can say is this gives a much better sound for what Analog is known for- and I had allowed to slip away all these years...
Cheers,
