That's my first "Hi Res" dap, I am amazed, sounds great with my custom Westone 3. I was not really convinced by the CD quality FLAC until now (hassle of compatibility, size, etc compared to 256kbps AAC) but the 24 bit 88/96 khz, wow. I'm sold. Now to find my fav albums.
 
Anyway, the US/Euro prices seem crazy, just bought one yesterday in Hong Kong. An A25 (16GB) for HK$1580, that's US$200.
Plus an extra 128GB microSD, but still cheaper than anywhere else.
edit: the A25, unlike the A27 doesn't come with the NC headset, but who is going to use it anyway?
 
Actually I was going to get the ZX100, yesterday was the release day of both models in HK but the A25 made a huge impression and I couldn't justify to myself to pay 3 times the price.

wonder if SQ is better than current A10

Hifiman seems power hungry, A20 won't be able i think, those need amp

Hifiman RE-400 and the new Sony mdr-ex750na - have both the impedance of 32 ohm (Sony with NC on. With power off = 17ohm).
Hifiman has sensitivity of 102dB/mW, they're rated 10mW, frequency 15Hz-22KHz.
Sony - 103 dB/mW, but their frequency range is much higher - 5Hz-40KHz (music for bats, anyone?  
So my guess is - they both will be driven equally.
 
Any comments on the internal memory vs external microSD card thoughts?

I use SanDisk class 10 UHS I, 40MB/s card and works fine, i never noticed stuttering or sound dropping, even wit flac 192Khz
 
Regarding the headphones well maybe this will be able to drive them, but i struggle with my 40-ohm MDR-1R's

Nice to hear, thanx. Do you fell like it has more impact on the battery, compared to internal memory? That would be the other possible influence.

Actually use both memories system and the Sandisk microSD  so i don't note aby significant battery issues, Playing hi-res is what affects battery life. Saw yesterday at anazon the Same Sandisk i Have 128GB costs 98 US i bought it in january 2014 when it was at 200 US... thinking of getting the 200GB one in black friday sales

 (if they apply only to usa, then i checl "Buen Fin " on amazon.com.mx)

Actually, I have to alter the previous data... As Sony's delivering the A20 series not with new mdr-ex750na, but with new mdr-nw750n, which are simpler (1 NC mic, as I see, lower impendance (passive NC?) and it's not easy to find any specs: http://www.sony.com.my/product/mdr-nw750n (even here there are contradictions, like "reproduce up to 40kHz" with "Frequency response 5Hz-24,000Hz" - how?!). 

 

[nekromantik]

Are the internals upgraded over the A17?
If you dont care for NC then is it worth the price over A10 series? 
As for power, I dont plan to buy any headphones, only use iems.

 

[McKolm]

AFAIK, no other upgrades besides NC. Just ordered A25 from AccessoryJack and to be fair - they're even cheaper atm than A15's there And I need NC since I travel a lot.

On AJ, the A27 is 32GB and £10 more then A17 which is 64GB.
The 16GB versions are same price almost.

 

[McKolm]

  On AJ, the A27 is 32GB

They don't have A27 on AJ yet, just A26, which is 32gb and is 100$ more expensive than 16gb A25 

I emailed them about availability of A27, no answer yet.

Sorry I meant A26 not A27.
Im in the UK so site shows UK prices. So its A25 for £128 and A15 for £125.
Then A17 for £188 and A26 for £198.
