X5 is not very portable and over my price range. :(
Only others in my price range is X3 and iBasso DX50.
sorry to disappoint but the A10 seems to be limiting the signal to 40khz. I know 20hz-40khz mp3 is a disappointment.
DSEE counts on the fact that your mp3 file will have killed a few things between 16 and 20khz(believing that noise above 20khz will improve your sound is like saying climate change doesn't exist). and it will rise those freqs with some nice noise that shaped to looks good next to lower frequency signal. so if you can actually hear well above 16khz, if your IEM doesn't roll off long before, then you might be able to tell how good the algorithm is.
for everybody else it will have the effect described by a reddit user talking about DSEE:
it's a little silly DSP, if you find mp3 not to be transparent, for real (or in your own head), then you just don't use mp3. I wonder how many people will say that mp3 isn't enough, and then would be happy to add high frequency paintjob to "recover"(lol) the lost signal?
Merci pour ton bon reponse, je suis content avec mon e 474 avec 128/192 kpbs et H3. C'est meilleur que le X3 et a un niveau tres proche avec 24/192. J'ai perdu mon xb-90 ex aujourdui, c'etait un bon deputy chien. Peut etre un jour, quand je connais le mystere de 24/192, et avant ca un plus belle ordinatuire. En revance, j'attend les nouvelles complet avec le MDR-1A.
I don't think x3 will be a big difference except for the much superior amp section.The ui is **** compared to walkman one though,thats a fact.
Why don't u save some bucks and settle for x1??
The reviews are very good on it and it costs just 110$.
But untill and unless review of A17 is out we cannot say anything.
get a nice little amp, to deal with power, impedance and noise level. that will get you to something really good for portable(but of course you must first be willing to carry it).
I prefer to avoid making direct comparisons as I owned the F886 only for 3weeks and it was some times ago now. memory isn't the most objective tool for sound. but at least they have the same "kind" of sound. so if you're not satisfied with the sound of the F886, there is no point in looking at the A15.
For members in Sydney Australia this Walkman is available at Sony Kiosk in Chatswood for $249 AUD (16gb version).
While it has my interest and the build looks great, I do need to hear from someone who owns FiiO X1 and the Sony.
My gut tells me X1 will give it a hard time, unless the Sony house sound is something you absolutely require.
I also wonder if myself owning an F806 too is worth trying this device.
