OP,
I don't mean to insult you, but I am suspecting you are NOT buying those LP's new. More than likely, even if bought new by you (as so many of mine were), they were played with conical and elliptical stylus, and 'stuff' got pressed deep down in the grooves, now to be found by modern 'deep groove' stylus shapes.
My friend has a ultrasonic cleaner he loves, but it does not clean my old lps as well as my vigorous scrub method does. I don't know why, but they play quieter after my method.
IF a cartridge can play a noisy LP more quietly than another cartridge, I don't want it, what else is missing along with the noise?
A great cartridge can kick ass on any type of music.
Speakers 'best for rock' were crap.
