    Hi

    I have a couple of IO carts currently undergoing restoration through a well respected technician...he would laugh at that one

    The first is a more recent Kondo IO-J.
    The second is a wonderful, early IO-LTD with rare battery power supply and custom made loom (by the said technician) for your tonearm.

    If of interest please let me know. Both will be sold as having undergone a full rebuild.

    Thank’s Ritchie

    Two very nice carts you have,
    But i would prefere a original rebuild at AN UK or Kondo

    There is an IO gold on a certain auction site. Somewhat old in years, but low mileage. With the relative low rebuild cost by IO a relatively low risk purchase?

    Not that Ive been looking....
    There have been two Golds listed recently.
    One on that auction site, resisted as they muddled its description. This an older type and from memory has a VdH diamond.
    (Rebuilds are reasonable so this could still be an OK price.)
    The other on a UK hifi sale site which was much newer- but I think this may have now sold.
    There were some at a Danish Audio Consultancy but I have no idea about these anymore.

    Rebuild of mine at Audio Note cost me 650 (to Io2 level)... was a few years ago but I'm sure still very affordable I imagine. They don't rebuild it as I understand it, they keep the body and the magnets and replace the cantilever/coil assembly.

    Should be possible to pick up an old Japanese one with the flying leads needing a retip for 800 or so if you can track one down.

    In my view this is the biggest issue. The output is 0.05mv which is tiny. The AN-S2 is affordable but not that great sounding/not really up to the level of the cartridge's performance. You really want an AN-S4 at a minimum to get the best out of it. (4k new, 2k second hand).

    A friend of mine has an IO rebuilt by Northwest Analogue and is very happy with it, he's still using the Audio innovations series 1000 SUT, is the AN-S2 the current equivalent?

    There are several flavours of the AN-S2, the one I tried with my Io (at the same time as the AN-S4L and Kondo-built AN-S6c) was the AN-S2L (like the others this has a high turns ratio of about 1:70 IIRC, for use with 1 ohm cartridges like the Io). While the AN-S4L and AN-S6c were reasonably close in performance, I though the AN-S2L was well adrift.

    BTW, I just found this thread on another forum:
    https://www.vinylengine.com/turntabl...p?f=19&t=89297
    There really is some rubbish talked on forums and some very bad advice given. All that stuff about raising the impedance of the phonostage so the AI 1000 transformer will work well with a 10 ohm cartridge is nonsense. The flawed idea might fit the grossly over-simplified theories bandied about on some forums but it won't work in practice - certainly not well enough if you've just spent hundreds of pounds on a cartridge.
    Rant over.
    It is confusing and unhelpful, I think to better the 1000 SUT, you're looking at a lot more money, interesting thanks.

    Thanks for that, there is a AN-S2L for sale on a well known auction site that we were looking at but after a bit of research, realised it's not going to be any better.
