Not wild variations , more unpredictability . Check out Bob Levi's Origo review , says something similar . So not the only person to have experienced this .... http://www.positive-feedback.com/Issue48/jorma_origo.htm
Thanks for that link.
Do you by any chance know where I can find Bob's review of the London cartridge that he refers to in that Origo review.
It's a cartridge I have been fascinated with for years but never made the leap because of its reported idiosyncracies. Now that I have a Townshend Rock V turntable (and its silicon damping) and Origin Live arm it seems less of a risk
