HI-RES DAP: Fiio X5 3rd generation or Pioneer XDP-300R?

I currently own the 2nd generation of the Fiio X3 and X5 when I replaced my iPods, and aside from the interface being a tad slow, I am happy with the products. That said, I am looking to upgrade my player. When looking at the reviews of the Fiio X5 3rd, it gets mediocre reviews with a moderate sample size. The Pioneer gets good reviews, but small sample size (7 reviews total). Does anyone have any experience in these DAPs? (Or any other kind?
