I'm getting closer to where I'd like to be with my vinyl 2ch system. I now have SDA 1A's driven by an EL34 integrated (super quiet even at max volume). I use my computer sometimes to stream music while milling about doing chores, but mostly I like to spin vinyl. Recently I picked up a very nicely built Hagerman Bugle phono preamp because I was un satisfied with the 60hz hum my Dynaco PAS3 was generating. The Hagerman is at least 60% less noisy than the Dynaco. Yay! Now I realize that the majority of the background noise is being generated by the Grado Blue MM cartridge! I swapped the cartridge with an Azden YMP20E and it is worse than the Grado. Do all MM cartridges generate noise? I was looking at the Clearaudio Concept MM cartridge, but I don't want to drop $200 and continue to have background noise, so I'm looking for recommendations.
