    Default Do I need an SUT?

    Hi guys
    I'm a little confused and need some clarity. I was looking to buy one of Marco's favourite cartridges, the Denon DL S1 and was wondering if I also need an SUT with my Primare R32 phono stage (specs below). I realise it's a very low output at 0.15mv.

    Input impedance 10, 20, 50, 100, 200, 500 ohms and 47 kohms
    Output Impedance 100 ohms
    Gain MM 41.5dB, MM with internal jumper 46.5dB, MC 62dB
    Signal to Noise 20Hz – 20kHz unweighted: MM -70dB, MC -60dB

    Thanks Steve.

    No you should be fine as your phono stage is suitable for MC carts.

    Thanks Jez, I presumed that but the output being so low made me ask the question.

    actually that's quite a normal MC output, nothing too low.

    It's on the low side, 0.4 - 0.2mv is typical these days.
