I've been talking with harman kardon about their hk 990 integrated amplifier to make sure the headphone out will be an upgrade from the one in my hk 3490 and they told me it uses the TPA6120A2.  I looked up the specs on google and it looks really high end but I saw some posts about it not being that great with low impedance cans like my ah-d7000's.  They tell me that it will still sound much better than the hk 3490 but there's no way to try it out since the hk 990 is internet only.  Thoughts?

Well shucks.  I just realized it's the same amp as the xonar essence stx I used to own that sounded fantastic!  Never mind!
