Madfloyd,
Check the VPI website. They sell their own version of the Dynavector which is probably the one VPIHW was talking about. It has an output of 1 mv and is the one I was thinking of trying before I (as I often do) went more expensive and tried the Benz Micro LP. It looks like a pretty good cartridge for the money. Unfortunately VPI is closed on Fridays and I'm sure for the Holiday weekend but I'm not sure I would try any makeshift headshell weight without asking them first. That sounds like something I would have done in high school when I was younger, faster, and more foolish. As I said before, you've got some great equipment(a descent phono stage may help as much as anything which doesn't have to cost a fortune) but another very important factor in vinyl satifaction is diligence and patience. You're on the right track and you will get there.
