I've learned so much from this still-brief thread. So much knowledge, and it's
based on firsthand empirical experience. Opinion and conjecture, "I read somewhere" or "someone told me", have little to no value for me.
That said, this question triggered a little pet peeve of mine (and no disrespect to the poster, he's asking a common question):
Is my system worthy of the "shibata" diamond?
I've used some very good cartridges on far less good tonearm/turntables. In widespread and popular theory, such cartridges
require a $5k arm on a $5K turntable. REQUIRE.
But they sound damn good. The improvements are dramatic, beyond question, everyone will hear them.
Am I hearing "the best" these cartridge/styli can deliver? Of course not! And I'll say it again in case some nit-picker (yes, there are some on AK) jumps on me: I don't even
claim I'm getting the best or even
near it. But the benefits are still very real.
If you have, or can get a cart/stylus better than the rest of your system, use it.
Unless, OBVIOUSLY, the arm/table is SO BAD it can damage the cartridge.
IIRC, Linn's first principle was "start with the source", and upgrade the rest as you can. The first source is the stylus, then the cantilever, then the magnet/coil structure, then the body. So hesitating to use a good cartridge because other parts of the system aren't good enough "in theory or opinion", is a misconception.
This is based on firsthand empirical experience. Believe it if you like, reject it if you like.
