RE: "However, nearly all MM cartridges have bandwidths less than 25-kHz...." Again?

> So how did you conclude that "nearly all" mm's have bandwidth less than 25kHz?

It is easy to conclude from calculating the resonance frequency of the tank circuit formed by coil inductance and wiring capacitance. If you measure all those cartridges you will undoubtedly find that their high-frequency response is down below -3-dB at frequencies above 20-kHz or so. It is my experience that most MM cartridges' frequency response falls off quite rapidly above 20-kHz. The problem is that only rarely do manufacturers provide frequency plots that go beyond 20-kHz and never do they specify the decibel limits of their stated frequency response. Therefore, their stated frequency response is often meaningless.
