Atmasphere,
No arguments of the electrical-mechanical fundamentals, but the aspect is not well doucumented for cartridges, and therefore, the nay-sayer(s) will debate. However, that being said, this document shows how the phono-preamp design can affect the performance. And, lets not even begin to discuss how Impedance is often incorrectly used for resistance, with Impedance = Resistance + Reactance and is frequency dependent, whereas resistance is fixed.
