+1 chakster! The EPA-100 is an excellent arm with removable headshell. This feature will not adversely affect SQ - contrary to what mc said.
Tonearm for Technics SP-15
I have a Technics SP-15 turntable with a Grace 707 arm and a Grace F9E cartridge with a Soundsmith new stylus. This combination sounds great but is limiting. The 707 tonearm has a fixed headshell and it does not allow me to easily swap other MM high compliance catridges or match compliance requirments MC cartridges. Suggestions welcome from those more expert than I.
