Ipod nano 3rd genaration vs M6 SL (8gb for both)

I get lost my great MEIZU M6 8Gb.
And I can't found it no more. I hope to found where I put it... but maybe I'll never do.
So I wish to buy a new reader, with the aim to sell it when I'll found my meizu.
My options are:
Meizu M6 SL 8Gb
or paying MORE but having it in less time, the last ipod nano.
Anyway I could pay the difference.
My doubts are:
Which is better?
Someone told me that last ipod have a better managment of playing list (and I think thats quite important).
But most important for me are: Quality of sound, I've great ear in earphones, and I need adjust treble, bass and so. In meizu M6 I found a great configuration.
How is quaility of sound of last ipod? Same? better? Worst?
Power of the sound, I need that audio aux in is more powerfull then normal mp3 reade. (Meizu M6 was powerfull enough when I put 34-35 or 40

So.... what do you tell me?

My impression on the iPod nano - M6:

I think the M6 has a better sound quality, especially the SL version. (It's got an audio chip that does less noise than the TP/SP as far as I've read the posts here regarding this issue.)
I think that unless you're listening to music on an IEM, then putting your music volume above 25, even with a negative equalizer is probably admaging your ear. 34-40 quite surely damages your ear, I wouldn't listen so loudly to it.

The SL's LCD screen is somewhat worse quality than the TP or SP screens. I don't know about the iPod's screen tho.

Indeed, the software of the M6 is probably a bit buggier than the iPod's. There is the stuttering problem of MP3s, the 2046 file limit on the player (might be problematic for your 8GB).

The iPod supports the AAC format (mp4/m4a), the M6 supports Ogg Vorbis, Flac, Ape (I think the iPod does not support those).
Also, you need to use iTunes for an iPod. If you're an explorer tho, you can set your iPod over to act as a data storage in iTunes and then can use drag & drop or winamp or something to upload songs to it.

Thanks for your reply.

There are many aims to use a so loud volume.
Mine is that I use meizu with my car-audio system. and it's half broke. So I can regulate volume just by external audio.

I found a quite cheap M6 SL, so I bought it. I hope that volume will be so loud as M6
PS
It's a pity that screen is worst. But nice to know that audio is yet better then M6.

Well, it's still quite watchable I believe, just a tad blueish. Hope your SL will make you happy then!
