A bit off topic here- I have a Sony Ericsson W8 (basically a re branded X8) which I had promptly rooted after 3 days of purchase. I proceeded to install a custom kernel and load in a custom ROM (now it's cm7.2). The music quality is great- with a relatively clean output with Player Pro and the DSP module- to my ears at least. I find it miles better than my old Nokia 5320 and my friend's new htc Explorer (stock ROM, stock music app- whose eq-s are terrible). The X8, as I found out has quite a bit of juice too- it can drive my Grado SR60i-s easily. Also it can play HD FLAC files without any problem!! The only caveat is my paltry 4 gig sd card.
Dedicated pmp-s may sound better, but it's a bit of a hassle to carry two devices which do the same thing all the time. I used to use dedicated mp3 players before, but after purchasing the X8, I didn't really feel the need to do so. Audiophiles maybe able to detect the deficiencies in the SQ a smartphone & a dedicated pmp can produce, but you gotta admit that the gap between the two has blurred quite a lot. So, I think a smartphone's a pretty good choice as a portable source nowadays. High end players like the Hifiman series and the new Colorfly one can make smartphones look like wimps when it comes to audio reproduction, but they aren't really portable and practical- especially in crowded, smelly and noisy public transports we've got in India.
