Got a PS vita recently as I heard they were getting out of stock and will not be resupplied. Its can be used as a decent pmp but beware you might run out of storage space.So anyone into gaming and love playing JRPGs (I know its a very small subset), I recommend it.
I would've shifted my entire collection if it were not for sony's amazing memory cards.
compared it with my usb powered audinst hud mini. its 110$ dac/amp, so entry level.
audinst fleshes out sound more ie more details, and is more 3 dimensional. It has more steps between quiet and loud passages and more dynamic. it also drives full sized hps like akg k550 much better.
Vita scores in smoothness department. Its completely grain free sound and with no harshness. I have never heard vinyl but from what I have read about it, vita sounds closer to that than audinst, cause no harshness. Also it cannot drive akg k550 well enough. I get enough loudness but instruments sound thin and it does'nt fill soundstage like audinst does.
but biggest surprise to me is Vita - Hifiman RE400 pairing. Sound is devoid of any grain or harshness, that can come up when using other devices. Also I think I am hearing more layers of music with this pairing but I need to double check.
I am planning to pick some mp3 tracks and fill internal memory with as many as I can jam in there, and use it with RE400 as portable rig.
When I want to listen to music, take out memory card, when I want to play games, put it in.
