pryso,
Thanks for asking.
Yes, I listen to mostly classical (about 90-95%) but I do listen to jazz, pop and some other styles. I had Grado cartridges for many years until I switched to the Clearaudio Virtuoso, which I like a lot. Contrary to your view, I’ve never felt the need to switch cartridges. My system really sounds fine in all styles with one cartridge. I’ve never felt the need to switch.
As far as turntable, I started out very modestly with the Rega RP3, but I have almost completely revamped and upgraded it with new parts and two power supplies. I also have a steady as a rock very heavy specially designed turntable platform on a slab floor which holds the turntable with no vibration.
