I got an Audio Technica VM95E/H cartridge and the overall sound is too bright for my taste. It also has a slight hum between songs sometimes. I have the model that came premounted in a head shell. If I continue playing this cartridge until it breaks in will the brightness tone down a little? Also, if I use my existing head shell instead of the one that came with it would that help the hum problem? I’m using a Gemini XL-500 II turntable, Sony 100 watts per channel receiver and Polk speakers. Thank you!
