Players that I've owned or know very well because I had them borrowed are: Cowon Plenue p1, Pioneer xdp100r, Astell ak300 and 380, Questyle qp1r, Pono Player, Shozy alien gold, Shozy alien+, Colorfly c10. I'm still at burn in with my wm1a (i'm over 100hrs mark) but I think only Shozy Alien+ is in the same league. They are completely different beasts however. Alien+ has raw, natural, very realistic and exciting sound and Sony is more refined and relaxed with better resolution, wider and deeper soundstage although it's darker sounding. Colorfly c10 still has the best midrange that is very analogue and tubelike.
