    Using an MC Cartridge Empty Using an MC Cartridge

    Greetings, once again, to this learned and helpful community.

    I have another question for anyone with an opinion.

    I' thinking to up grade my phono cartridge to a low output moving coil, but to do this, one needs to step up the signal so the moving magnet input on the pre amp can deal with it.

    I'm reading a bit about Step Up transformers, which can be difficult to mate to the rest of the equipment and, I understand, can act as a filter, cutting the frequency response down. (I think I have that right)

    The other major option is a so-called "head amplifier", to actively amplify the signal.

    I'd sure appreciate recommendations, and I'd prefer to go with a DIY kit, if there are any.

    Thanks,

    Brenton

    Brenton,

    Do you have any phono stage on your preamp now or is it just a line stage ?

    Hi Bob,

    I have the Transcendent Phono Stage running into the Transcendent Pre amp.

    Brenton.

    The Transcendent phono stage can be used with moving coil cartridges but may not have enough gain for very low output moving coil cartridges. IMHO you should probably stick with a medium or high output MC cartridge. Some phono cartridges can get pretty expensive and some step-up transformers can be expensive also.

    If you do want to try a low output MC cartridge I know that Jensen makes some reasonably priced step-up transformers for low output moving coil cartridges. Check the link below.

    Hi Bob,

    Thanks for this perspective, and for the Jensen Link!

    Hi Tube Nube

    (I have been away for a while - job related - again!)

    There is a a high-output MC cartridge that I can whole-heartidly and without any qualms recommend (and therefore solve the step-up transformer problem):

    The Denon DL-160 (and it is relatively CHEAP!)

    It is a mind-blowing cartridge, seems to have quite the fan group - and puts some other expensive higher-end MC cartridges to shame. I bought one from the Needle Doctor (IIRC) as a "cheapie" thinking that it will serve me until I can get around to buying a high-end MC (I'm kinda broke at the moment - kids at college etc), but frankly I am totally happy with it.

    Excellent dynamics, stereo imaging, 3D imaging, works for Classical, Jazz, Rock...
