There is no comparison, IMO. The PA2V2 sounds muddy and lacks detail/resolution, while the XXS/Headsix sounds pretty good.
Maybe the PA2V2 helps driving somewhat demanding cans on really wimpy audio players but if you have a decent player the PA2V2 most likely makes the sound worse.
FWIW; both my 300 Ohm HD650 and my 80 Ohm DT770 sound better directly from the Cowon D2 than from the PA2V2.
