Does anyone know how to speed up library creation with the 64 gig card? It takes my a 17 six minutes to get this card ready. I have the same problem with my 128 SanDisk card.
depends on the card itself mostly. now if you don't feed the internal memory up to the last octet, that might also help for a few jobs.
and of course if you repeatedly change the card's content, it may become fragmented and slow down the reading a little, but with flash memory that shouldn't be the main reason.
also maybe try to load the card with media go just as a test, as it will not upload problematic files, so if the scan becomes clearly faster, you would know that you put something wrong on the card.
I've not heard the NWZ-A10 but I did consider getting one before I bought a Fiio X1.
I've had several Sony's in the past (NWZ-A729, NWZ-X1000 and NWZ-A846) and they've all been pretty good, but a bit overrated IMHO.
The Sony DAPs I've owned have all had noticeable background hiss when listening with sensitive IEMs. I've seen some comments in the NWZ-A15 thread about people hearing background hiss (though I'll admit most people say it doesn't bother them or they don't hear any) but background hiss on a DAP really annoys me. To my ears the Fiio X1 has a totally black background so, for that reason alone, I prefer it to any of the Sony DAP I've owned previously.
The EU volume limit on Sony DAPs I've owned has also been an issue in my opinion. I appreciate the reasons for a volume limit but I always felt the limit was set too low.
In terms of UI, the Fiio X1 is pretty basic but I've had no issues with it. You can update the firmware with your own custom theme (which I've done) so it looks okay, and I've found it perfectly usable. The build of the Fiio is solid and I actually think it's quite attractive (though I didn't think it was a great looker before I purchased it). Sony DAPs do have a more polished UI, but not to a degree that it would effect my decision, and the NWZ-A10 build looks a bit too slim and flimsy for my tastes. The last Sony DAP I owned (NWZ-A846) has a similar design and build to the NWZ-A10. I didn't like the ergonomics of it (too long and thin, with the control pad too close to the bottom edge) and I accidentally dropped and broke it within a fortnight of buying it.
The Fiio X1 battery life isn't an issue for me, as I never stray far from home, sit at a computer most of the day, and it's not a problem for me to plug it in and let it charge regularly while I work, but I can appreciate that the far better battery life of the Sony is preferable.
So far I've been thoroughly happy with the Fiio X1 and have no regrets about buying it rather than a Sony.
But I will admit to being curious about whether the NWZ-A10 has improved (or not) on the issues I've had with previous Sony DAPS and I would quite like to test it out just to see.
overall what you say still stands for the A10 series. in fact it is even longer and slimmer, side buttons would have been a nice thing IMO.
now about upgrades, battery, flac, highres, µSD card, remembers the last track played even after more than 24hours idled(if on latest firmware), the karaoke stuff went down in the menu list, NFC, the shape of the buttons makes it just a little bit easier to find the right one compared to mickey's head UI, and lastly, the DSPs while keeping the same names are slightly improved each time(surround stuff are now more than ugly blur).
but the main problems did remain: high impedance, hiss, stupid line out cable, "sens me" scan takes many hours... on those points, the X1 is very clearly superior, and probably one of the best sound/$ gear on this forum. of course that makes it a great DAP if you get clever with the way to organize the folders as browsing sucks big time.
I have both, keep both, think the X1 sounds better(and it does, if only for the noise floor), it can also drive a wider range of headphones, but I use the sony 99% of the time, because its a great portable source that lasts forever, can deal with my audiobooks without making a mess when I shuffle all, and is light.
so I guess, best sound people will go for any fiio they can afford, and practical people will go for the sony because it's convenient. but it would be wrong to call one better as a whole, too many differences and too many fails on both sides.
