    The 95 only outputs 3.5mv so not the loudest cart around but saying that it shouldnt be low and muddy.. tracks at 2gm aprox and loaded on mm at 47kohm. Make sure if the pre has a mc setting or loading options that you have it on mm and 47k. Also check you have the cart leads on correctly.

    Got a feeling its not marked on cart so you will need an online diagram to show what colour goes where. Its not same as other carts, if memory serves.

    Are you sure the tags are on the correct pins? It occurs to me that an out of phase cartridge could be a potential cause of the symptoms.
    I've checked the tags with the pins using the chart that came with the cartridge and also the manual for the dual that I got online. I think I've got them right, although the cartridge only has a + sign and L and R (not a - sign). I'll give them another go and crimp them and come back.

    Thanks again for all the help.

    I've tried 2 preamps. The Nad is definitely on MM and the Berhingher is only MM. Tracking is at 2gm. Not sure about 47kohm, as I can't see anywhere to set that on the preamps, and I assume they are at the right levels.

    I was half-hoping I'd got them the wrong way around, but no, that's how I have them. Just re-connected them and crimped harder, but to no avail. It's listenable at about 2 O'Clock on the amp volume cranker, 6 O'clock being full blast, which would break windows with the CD player. But, the hum from the amp is noticeable after 1 O'clock and I can't help feeling something is amiss.

    unlikely but possible both pres are faulty. amp working with cd ok suggests its ok. faulty cart setup, faulty cart, something wrong with the tonearm wiring maybe.

    So, you're against the "it's the amp" theory? And, should I be getting that hum from the amp at high volumes?

    Hold the front page! I may have exaggerated the volume from the amp, with the CD player. It now seems pretty quiet at about 1/4 volume (9 O'clock) and needs to go to 11 'Clock to be listening in my large room, and then to 1 O'Clock to be loud, so only about 2 or 3 "notches" behind the turntable, if I'm honest. The hum comes in at about 1 O'clock.
