    Regarding the distortion at bass frequencies, yes, graphs show the distortion does go up, but remember, that measurements are made by and large at a constant 100dB output, which means, with a huge bass boost already applied (against the natural downslope of the 'phones), much more so than the one applied here. Also, music content itself slopes down in those frequencies. So the distortion you'll encounter in use of this combo is doubly not as bad as graphs suggest.

    That is a quite well done EQ for the 6xx. Think the only way I would personally improve it would be to not boost the 20-30hz region so much. The 6xx has quite high THD there and never will have particularly amazing slam due to the drivers only being 38mm. The boost from 30-200hz will be much appreciated though. Wont be a big issue for most music I guess as most music has very little going on down there, but might make it sound a little less clean than it could otherwise.

    The lower treble boost is very nice and well done, the 5-6k dip is biggest flaw the 6xx has FR wise IMO. Guessing for the average person that will be all the EQ you need.

    Edit, lol Joe replied as I was typing this about the distortion. Or perhaps I just didnt see it because I am tired :)

    I don't really attempt to boost the lower regions (especially beyond whatever the baseline DSP applied by the model specific curve) on the 6xx using SW, as it just runs into what I think are mechanical limitations, but it improves it a lot when it comes to the upper mids and lower treble. Just opens it up, ironically making it more like a 600 without the shout.

    My Dynamat/coin/spider-modded HD650s take a bit of subbass boost quite nicely. It's still HD650 bass, but the increase in lower frequencies fills out a lot of music nicely without being too loose and woolly. The Zen EQ curve seems to boost midbass , which makes them sound worse to me (I pull down about 2dB from 150-250Hz). I'm also pulling down a bit around 3.5kHz for tracks with honky-sounding female vocals, but will try playing with the 6-7kHz range, even though mine don't have any perceived veil.

    For those of you wondering how other headphones from the Sennheiser line would match up with the ZEN CAN Signature 6XX, here are our predictions based on measurements |\/|

    The curves are very similar when we normalize them to 90Hz. (The iFi uses a lighter touch).
