    Default Denon DL-301 mk2 match with Technics stock tonearm + What headshell to use?

    I was considering Denon DL-301 MK2 after reading a lot of good reviews. My question is, what about the headshell. I would like to update the stock headshell, but technics tonearm has 12g effective tonearm mass. And all the good headshells I see are 12g, so a little math:
    (12-7.5+12) = 16.5g - effective tonearm mass with the new headshell.
    where:
    -7.5g stock technics headshell
    12g - new headshell

    And this will move the resonanse to a point, where it's not good, right?

    Do you guys have any suggestion for a good headshell, that will sound better than the stock one?

    I used this calculator, and for total mass 22.5 + 10Hz desired fr. equals to 11.258 cu.
    The DL-301 has Compliance: 13x 10-6cm/dyne

    But I'm not sure in what units the cu is in the calculator, I'm still new to this stuff, any help will be appreciated.

    Denon quote the compliance at 100Hz, whereas one really needs the dynamic compliance at ~10Hz. Depending on the exact cartridge the compliance at 10Hz is 1.5 - 2.0x the compliance at 100Hz.

    The Denon 301/II has a quoted compliance at 100Hz of 13cu, so we will calculate the resonance frequency for 19.5 - 26cu. With a total mass of 22.5g, the calculated LF resonance frequencies are 6.5 - 7.5Hz. These are IMO too low, but depending on where and how your turntable is seated, you may get away with it and not experience any problems.
