    Yes, the ART7's output voltage does seem to be alarmingly low. It is 12dB lower than the ART9, so into the same mc phonostage you would expect the signal-to-noise ratio to be 12dB worse.
    If using a step-up transformer you would need a pretty high turns ratio between about 1:30 and 1:40. If using a headamp you would need about 30dB gain, and a very good-signal-noise ratio.
    Personally, I would be more tempted by the ART9. Much easier to work with, as DiveDeepDog says.

    You'd be missing out on a truly high end cartridge if you discounted it due to its low output. Sure, signal to noise ratio may not be as favourable via your reasonable theory, but if you have a good phonostage, that shouldn't be an issue, should it?

    Heres the AT-ART7 I'm going to be playing with.

    I'll feedback any noise issues from the low output although my phonostage is very good and very quiet so I am hopeful of no issues.

    It wouldn't matter how good the phonostage is, it will still be 12dB noisier than with an ART9.

    Yes, that would be interesting. Noise theory is one thing, but in practice there may be no problem.
