    I am after a recomendation for a headphone amp with enough power to run the voltage hungry Akg k240DF and sextetts (both 600 ohm)
    I am thinking of the matrix mstage ss amp with adjustable gain or the bottlehead crack otl valve amp (diy kit)
    Also SQ is also important as well as power as these headphones are a bitch to get the best out of them (high Z + low sensitivity)
    The DF are the hardest to drive and sound a bit boring out of the xcan v2 as i dont think the v2 is really capable of driving them as well as nearly having the volume on full to get any loudness out of them
    I also have the K501 which are also a pain to run
    Akg k240df are 600 ohm, 88db spl/mw, max input 200mw.
    The sextetts are the same specs but the sensitivity is 94db/mw
    This is the link for the bottlehead crack amp
