'i've got an early Planar 3, and the anti-skate thingy on the R200 arm seems to have failed,and I also am looking to an upgrade. Origin Live have replacement arms, but where do you stop? Then there's a new motor available, but I'm unsure of how much improvement this would give. I have a Dynavector 10x4 cartridge, so perhaps upgrading to an RB300 would be the way to go? Or an RB251? Moth? Origin Live? There seems to be a few versions from which to choose, hopefully not too expensive. It's not easy to audition these mods, is it? Has anyone else gone this route?
