nice to meet you all guys, this is my first post in heaf-fi, so soory that i only able to write in very simple english..
i owned NWD E25 3 months ago, from item listed spec it is almost some with latest walkman series like S739, weeks later i went "sonystyle" shop to have a check model by model later then i realise different model which seems same spec actually come out quality differs.
The best sound quality (flat and EQ) goes to "
1.S73X( my country do not have S63X series) series, then
2.A82X and A81X series, follow by
3.E walkman series, later only
4.Sony NWD E02x stick series.
5.new launch megabass stick
DSEE make too little difference that i never use,
Clear stereo make abit difference..
@@the sound quality very differ for E025 vs S639(S639 same sound with S739)
@@ my personal views is ,S739(S639) superior sound beats other players in the market, player come close to S739 quality r Cowon D2 and fuse.
after comparison, i store my E025 somewhere inside my room, and i having S739 with my ear >3hours per day.
...
the sound quality make me addicted to it, but it is not the end of music coz the earphone bundled make even huge differences..
so from E025 earbulb > S739 earphone(not bad) > EX90(better bass,but mid suck) > finally...just order a set of Westone 3(sounds better then shure 530 and fi10 as i test >2 hours listening).
thus my personal belief is Sony S739 + Westone 3 = the best sound quality for ever portable mp3 up till today's technology.
regards.
