OK.......I need more info on the Shelter 901......

Cp, no the cu is compliance units, and has nothing to do with your internal impedance. Compliance can also be expressed as (c)x10^-6 cm/dyn. The Goldring spec was given in the other metric version (c)um/mN. This is micro-meter/milliNewton. It is another way of saying the same thing. Just pay attention the the first number in these specs, that's what everyone refers to.(like 12, or 15, or 9, the numbers I represented with the (c) in my examples.)

Thanks for clearing that up, twl! I think I get it!

I just bought a Shelter 901 from Japan. No, not from www.eifl.co.jp. I got it for even cheaper from another dealer in Japan that came highly recommended on the Audio Asylum discussion board.

I have an SME V. This is the first time I heard about the discussion on this "cu" thing. Should I be worried?

I also have the PH3 SE. I heard that the output on the 901 is actually higher than 05mV, so it shouldn't be a problem. I am planning to install the cartridge this week.

Frank, don't worry, it'll be fine on an SME V.

Hopefully, I will find time to put it up in the next couple of days.
