I have Meizu M6 and paired with Crossroads Mylar3 before with Spatilizer on. Sounds fantastic like BBE or SRS WOW enhancement added! The downside is it drains your battery life very fast!
Now have upgrade IEM to Atrio's M8, with Flat EQ setting, bass boost set to 3, treble boost set to 1 and have the Spatilizer turned off. Results of very warm, clear and crisp sound and wider soundstage with approximate 30 hours burn in. You can hear the bass output difference from the bass boost setting alone, very tight!
(Oh my battery life has improving!) Might getting Etymotic ER-4P next month.
I do wanted to get a new player, but very unlikely now because not all players support FLAC format, shame. So considering to get a portable amp for sound upgrades. I am very satisfied with the current M6 useability, battery life, size and the 8Gb storage (damn only left less than 1Gb free storage now
).
Nowadays I like to listen to Flat EQ with a little bass and treble adjustment and paired with high end IEMs so Cowon is not in the list. Read the Zune 8 reviews and claimed to have crisps and clear sound, but lack of FLAC support and hate using the software to transfer the music into player but would prefer to use iPod iTunes instead.
iMod is too bulky for me, considering everyday commuter to London, dont want to stuff bulky and heavy objects in my pocket he he.
Back to the topic, although I did not try other player sound quality, but so far I am satisfied with the Meizu M6 SQ. Maybe you should upgrade your IEM before changing the player.
