http://www.cowonglobal.com/product_wide/PLENUE2/product_page_4.php - now in English, good side by side comparison of P2 vs P2ii spec, as you scroll down.
Looks to me like a refresh/optimization with some very noticeable improvements: 256GB internal bump from 128GB, 3.24Vrms BAL out (also bump to 2.6 ohm output impedance), bump to 10.5hr battery (from 9hr), improved crosstalk spec, new chassis color, and now with a premium Dignis designer case. I would expect the same tonality, since DAC is the same and I don't think they are changing head-amp section, just optimizing the performance. If indeed the price remains the same, this is very impressive. Will see if I can get it in for review to compare to the original P2.
