  • Compliance on sme 3009 arm series 2

    In reading up on the above arm and it’s setup there are some notes on compliance
    from what I read compliance in part is effective arm weight
    meaning low Comp needs an arm that weighs more.
    The above arm had some optional arms that were made for low Comp cart
    I have alum the stock ones the cart is sound smith sossuro mkii it’s a 10 u cart Comp
    any advice on this.
    i set it up fast last night
    effective arm length
    VTF 2.0
    azamith using the fizzo meter
    vta stock.
    It’s on a td125 sounds very powerful so far but does possibly have some odd tones at times. It has no simbalance or fuzzy bass. Has a good tone over all.
    So my question is how do I know I have good arm weight for it’s needed compliance ?
    sorry for any misspellings or outright dumb questions lol.
    Any ideas ?

    You're correct that, generally, low-compliance carts require an arm with heavier effective mass. However, I'm using a Soundsmith MIMCStar with the same compliance as your Sussuro mounted to an arm stated to have 9g effective mass. It sounds very good (after the new phono stage and all the new cables settled down). If you've got a test record, it's helpful to determine the resonant frequency of your arm/cart combo. That might throw some light on the odd tones you're experiencing. Here's a link to info you might find interesting:

      You can use this to evaluate the resonance frequency. You want to be in the green zone......
