Sorry I know this is off-topic.
I auditioned the HP-P1 (with Classic and JH13s) recently at Jaben. It was brief, and I tend to hear a little less well in Jaben (I don't know why).
TBH, it was a little underwhelming for me. Yes, it widened the soundstage quite a bit, and sounds were more focussed than before, but vocals also became a tad less intimate in some cases, and overall dynamics didn't improve significantly (should I be looking at Amps more than DACs for this?). Overall, it just didn't strike me as a product worth buying, especially given its cost and (lack of) portability.
Am I alone on this?
I can't say if you are the only one who thinks so, but I sure don't. I'll go as far as to say that I think people are wasting money amplifying poor sources. Even compared to my diyMod, the Fostex improves in so many ways. Maybe none of them earth shattering, but all of them add up to an experience that makes me think it is very worth the money. I have noticed dynamics improving significantly, especially percussion...a drum wack really sounds like a wack!
