It's very possible I discovered that track from your post then. I can't remember haha!   I went with the black with red highlights. It barely won over the dark silver color. Actually I'm still not sure if I made the right color pick. :/

At first I was not terribly blown away. The low-end bass felt a little reserved and the high-end bass felt a bit exaggerated as if to compensate.     After spending a week with these, I have to admit I am now quite impressed.    They now feel much more balanced. Often lots of agressive...

Well I went back and redid the gain setup on the pa2v2 using my hd 555. No success.   I'm now convinced the pa2v2 is simply not good enough for a pair of headphones of 55 ohm impedance and up. You lose huge amounts of sound definition and quality. The sound is simply gutted.   I've found...

Quote: Thanks for the reply apatN.   I agree with you. If I were reading this as someone else I would of thought the same thing. The sad thing is every time I go back to adjust them, there is no position whatsoever where the HD 555 come to life. They certainly get louder but the...

Hi all,   I have been lurking here for several years now. I've been a happy owner of a pa2v2 for more than a year now. It gives great sound in all my in-ear earphones and my low-end over-the-ear headphones.   Unfortunately, the pa2v2 has failed completely at powering my Sennheiser HD555...
