I'm about to take the plunge on a new pair of headphones. It's between the HD650, HD600, and K702.
Current set up is Zero AMP/DAC 09 version and a Astro A40 mixamp (for gaming).
Looking at these three headphones for music purposes so I'd be running them through the Zero. I've been listening to my triple fi 10's at work a lot and just adore the sound of them. I get most of the bass of my Denon D2000's but only where its supposed to be, whereas the D2000's seem to give bass when there shouldn't be any sometimes. But i really love the highs of the triple fi's. Full of detail but not harsh at all. Trance in particular,and especially with female vocals, is just incredible from the triple fi.
That sort of sound signature is what i'm looking for in these phones. This is going to be for home use, as I don't like having the IEM's in my head all day. I don't intend to get rid of the Denons, but the slightly too "always on" lower end and the somewhat harsh highs get on my nerves after awhile. I'm going to be using the Zero amp for at least the next year or so, though i'm sure reading this place enough will convince me to upgrade in the future. Would any of these headphones be an upgrade to the triple fi in sound, and which would be in a similar ballpark in terms of sonic signature, while still being good for Rock bands such as Porcupine Tree and Opeth?
One last note...comfort is an issue. I have the Sennheiser PC350 headset and i have a difficult time finding a good fit because the angle of the ear pad tends to raise the bottom of the ear cup off of my head slightly. I can fix this by extending the headband, but then it sits unnaturally low on my head. Is this an issue that I would likely face on the 650/600 as well? On the denons I generally use them at the smallest setting, and find they fit just about right.

















Its sex for your ears.
