Stylus lifespan

    I would hope the arm doesn't follow the groove and it is just the cantilever otherwise the coils/magnets won't generate a signal.

    Exactly so, or at least ever more of the information from the groove would translate to arm movement, as the effectives masses approached one another.

    It is often overlooked that high compliance and low tip mass *also* mean that lower levels of vibration get applied to the arm by the cartridge as it tracks the groove. This means that arm 'ringing' resonances matter less because they aren't being excited so much.

    And less need for super rigid and low slack bearings (SME 3009 S2 plastic knife edges)

    I find it depressing that some feel they have to ration their vinyl listening owing to the expense of the carts they have chosen.

    Well it seems I play vinyl tonnes more than many people on here, so once a year is may'be even too infrequent to change styli. After replacing my Nag it now sounds divine straight out of the box. Wonder is the MP500 worth triple the price? Although replacment styli are only double the price, so that's £400 for a bit of plastic! (MP500 new cart = around £600 direct from Japan, new styli = around £200 direct from Japan).

    For me it's the inconvenience of vinyl as a medium that accounts for the low number of hours I've clocked up on my cart, not the financial implications, but I can sympathise with those who spin daily and have pricier carts to up-keep. First world problems of the afflicted audiophile... :)

    If the stylus, made from a very, very hard material, wears like that, think about the fine grooves in the soft vinyl...

    The difference is time at stress. Each 5 um spot in the groove sees a milisecond of stress, while the diamond sees 1200 seconds per side.

    If I scratch the paint of a car with a rusty nail, each 5 um spot of paint sees a milisecond of stress, while the nail sees 12 seconds per side... :)

    The main reason that I now rarely play an LP is that for years I made a decent digital capture of each one when I fancied playing it. That done, I keep the LP safe and play the capture. Less faff, less stylus wear, etc. :) When I occasionally buy a new LP I go though the same process.

    The reason I rarely play them is there's so much choice these days! But when I do, I thoroughly enjoy it.

    Stylus life is a bit of a difficult one. For example, I use several turntables, so the cartridges (Dynavector XX2MkII, Dynavector DV20XL, Goldring rebuilt Troika) get fairly even use between them , so their life is extended somewhat. It's a good way to run a vinyl system if you can accommodate more than one record player. Also, in my case life-style (work) means I don't get as much time with the system as I would like. But given that I had more time, I doubt that I would ration the cartridge use; one reason not to use a cartridge that you can't afford to replace when it wears out!

    Interesting research, how many car sides does the nail last?

    Any tips on a USB microscope to use? I see one on Amazon at £13.99 will that do?

    I think the MP500 is more like £250, and that's before import duty, it will be more like £300 before you've done.

    I've imported 2 carts from Japan now, didn't pay import duty on either.
