    Focusrite Scarlett 2i2 USB interface
    Analog Output Impedence is 10 ohms

    New to all of this, so I am wondering if I could use these headphones without the need of a seperate headphone amp.

    These headphones are the ones I have researched and am trying to decide which one to get for best flat, neutral sound in my price range.

    ATH-M50 ---- 32 ohms (can possibly get m40fs, although they have 60 ohms)
    Audio-Technica - Microphones, headphones, wireless microphone systems, noise-cancelling headphones & more : ATH-M50 : Professional Studio Monitor Headphones (with coiled cable)
    Sony MDR-V6 ---- 63 ohms
    MDR-V6 | Studio Monitor Series Headphones | Sony | Sony Store USA
    Sennheiser HD 280 PRO ---- 64 ohms
    Sennheiser USA - Professional DJ Headphones HD 280 PRO - Noise Cancelling Closed Circumaural Headphones - Personal Audio
    AKG K240 ---- 55 ohms (not considering these too much since they are semi-open back)
    K 240 MK II - Specifications

    Now so far, I have picked these since they are recommended as flat, natural sounding headphones in my budget.
    Although, I have found out I may need a amp to get the full potential out of the headphones.
    According to,
    NwAvGuy: Headphone & Amp Impedance
    It seems I should have my output impedence an 1/8th of what my headphones impedence is. From that it seems the ATH M50 would be closests, but still not quiet there.
    Just want to check with the professionals before I purchase.

    By the way, which seems best for a flat sound according to this chart:
    As for the Sony MDR-V6 compared to the Sony 7506, they are just about the same, although when I compared them on a chart just like above, the V6's were actually more flat. Which is what I am looking for.

    You shouldn't need a separate headphone amp. The front-panel headphone jack on the Scarlett 2i2 is designed to drive most types of professional or semi-professional headphones acceptably.

    Although the 2i2 specifications are lamentably unclear on this, my guess is that the figure given as <10 Ohm for the output impedance relates to the rear-panel line outputs and not the stereo headphone jack.
