Hi thanks for the warm welcome.
I should've been little more patient when building current system, but being a couple of years without sound equipment after my separation I hurried with sources. I mean I now see I would like to own a TT capable of interchanging headshells to have the pleasure to compare for myself how different cartridges track, there are so many good cartridges, even used, some on reachable budget. Pioneer's PL640 is nice but fixed headshell unfortunately. I may need to hunt for a good vintage TT that would match my setup. In the meanwhile I have a cartridge scale, a blank vinyl record on the way to help me adjust this trusty TT the best I can.
So in the inmediate I will be with the physics and mechanics,,, drill, hummer, screwdriver,..
Alvaro.
