@dnicol,
The timing of your post is uncanny. Prior to last week, I had been playing with a zyx ultimate 100, the entry level cartridge at 5 g - very enjoyable. More importantly it worked very well with the Terminator, I got to experiment with pump, surge tanks...etc without worrying about the compatibility issues, weight, compliance...etc. And it was pure luck.
Last week, I installed a new cartridge, Audio Tekne MC-6310. There is no information on weight or compliance that I could find. I have not measured, but it’s probably 9-10g. I have set the counterweight as far back on the wand as possible using the supplied single copper disc, 5g. The MC is positioned as far out on the other end as possible, tracking at 1.8 g. I thought I had it with the first few days of listening. Then last night, playing a few records ( Bill Evans’ Tokyo and Paris concerts ), the sound became unlistenable, the piano was shrill, soundstage was off...etc. Not until reading your post did I know the problem. This morning I added weights as you described, but in the 5-7g range, not as heavy as where you ended up. And sure enough things began to turn for the better. Records I thought was good have now deeper soundstage, more transparency...etc, and ‘bad’ records are coming around.
My question is how did you arrive at the 12g weight on the cartridge end? I know our cartridges are probably different, hence different compliance. I may not end up where you are. But wondering if you had gone over 12g and found it not to be optimal?
