E12a vs A5 interesting thread!!! http://www.head-fi.org/t/819831/the-fiio-a5-thread-an-upgrade-of-e12a-muses02-lme49600-800mw-19vp-p-12-hours

T3 !?! If you refering to new X3ii, it's a small dap, and in this regards, 2 microSD card slots will be more appropriate than standard SD slots! IMO Just buy an SD to micrcoSD usb adaptor for more convenient... like i do! Have many kind of OTG cable converter/adaptors.

Agreed! No need for SDXC cardslots... I'm using it only on my Nikon! ... I think 2 regular, standard SD card slots will be, imo tooo huge for a so small dap. 2 regular microSD card slots will be welcome instead!

lol Wait, X3ii has just being freshly realeasing ... it is still young! :D

I can recommand FiiO X5ii or X3ii DAP with your e12 & HD600, they will pair better. Keep your note 3 for talking with friends. :D

Yep, the best... pairing with high imp. HD. But pairing with low impd. IEM the E12a is more appropriate. But, if I want to pairing with my IEM and HD600, which of the 3 is more appropriate to buy, for both phones?

Umm! Have heard that E17k are best over the E12/E12a. I will have to decide between one of these using with... Westone 4r IEM / HD600 / X3ii

E12a vs E17k with Senn. HD600 (source: X3ii)

What about my suggestion with the Spec-ops cases ? Are they ship to your country ?

SPEC-OPS brand make good cases for that purposes. Military/Tactical Gear in mind. I'm using one for my DAP (X3ii) and one for my GS4 phone. Hope you like the gears! Proudly made in the USA https://www.youtube.com/watch?v=IyWpm1lRadM http://www.specopsbrand.com/t-h-e-phone-holster.html/

What about using E12a + FiiO X3ii with Senn HD600 (300ohm) !?! Is E17k will b more appropriated ?

Ya, I know, it depends on my preference.Humm! I realy dont know if I already know my preference !?! which of the two best reproduces female voice? Accoustic guitar&piano.alternative, soft rock... Adele, Jennifer Warnes, Agnes Obel, Melody Gardot, Norah Jones, Sarah McLachlan, Deep Forest...

Yep, but with female jazz vocale, accoustic, alternative... what your pick ?

Hi Paul! Thanks for the great helpfull review! I've read almost everything. I'm still hesitating between those two though. Which one would you recommend with using my FiiO X3ii. (Adding E12a or E17k if required) I mainly listen to: Vocal jazz, (female), soft rock, R&B, alternative, accoustic...

You just have wish to get phone calls from X3II - 6s is a phone ... X3II is a DAP ;)
