Well, the headphones are a Grado SR80 and a K702.

If I generously assume it has a 0 ohm output impedance for simplicity, and assume that was measured with a 16 ohm load, that's about 1.8 Vrms.

 

Now all we need to know is what headphones you're talking about.

The PA2V2 is plenty for the Grado, maybe not enough for the K702 depending on how loud you listen.

 

But I suppose that also depends on source voltage. What do you plug the PA2V2 into?

 

I don't know what the PA2V2's gain settings look like. If they're going for 2 Vrms it might just be 1x gain.

Using on a laptop now with a realtek HD soundcard.  If it does make a difference, I was gonna put the Xonar DG in my Desktop with a Intel 2500k chip.
