I have the improved collar from Ammonite Audio for my 750 arm which I haven't installed yet. I'm glad Jelco addressed this issue with the new tonearms. I'm about to pull the trigger on the new 850 arm.
comparison between Ortofon TA-110 and Jelco 850? I have a chance to buy a used TA-110 for a little less than the Jelco, so I was wondering if you could shed some light on the differences you have noticed?
These look a lot like the Ortofon tonearms. I cannot find any info on these except what I've read here. Any links to more info would be much appreciated. I'm running SA 750 arms on both my Oracle turntables, and might be catching the upgrade bug.
