Well, the problem with my ZX2 recently that I realized....the lower-trebles were weak and appear lacked of energy....in non-enhanced sound effects form
Hell, it had been a few days that I tinkered with the Walkman app and the effects of enhancements. The uses of EQ adjustment within the app couldn't even fix this without ticking other enhancement options.
1/ if the "Clear Audio +" is on, the sound field appears a bit artificial with that halls effects and reverb ? And if used with any non-flat gears, the sound will became hugely more v-shaped. And it makes the vocal fall back very noticeable. I can see if someone is used to just non-adjusted/enhanced effects dislike this so much, just like I do. Well the problems is that to folks who don't really cater toward the "Accuracy, and analytical", but just want music. I can see it is an excellent feature.
A/ it helps immerse the listener into a deeper, wider, larger sound of field
B/ more V-shape = helps the musical flow better and more continuous with fluidity
C/ it also boost the "lower-trebles" which was weak in a non-enhanced form.
Also, somehow the volume is a little boosted over-all
*****But to folks who prefer "realism, accuracy". It is ugly because
A/ artificial soundstage
B/ V-shaped, that make heavy bass instruments like large kick drums etc....sounds muddy, and in no way realistic, but more like boomy and bangy
2/ If DHSEE HX is on, the sound will mostly remain Flat, and a little boost on the trebles...more like a little spikes, and that make the trebles while still being lower-trebles weak, the spikes make almost the rest of trebles spectrum kind of feel artificial just because the whole tonal body is not exactly there. It is not really that noticeable though, mostly it would sound just a little sharper on the trebles end from normal observation
3/ if Surround sound "Studio" is on only "The best sound enhancement" in my opinion. It helps artificially expand the field of sound a little larger and wider, not by as much as clear audio, and it also does not V-shape the sound too much. Due to this, the sounds seperation got a little better while still remaining flat. Still artificial though. Somehow the trebles tonal body is with better resolution and energy. But lower-trebles still may not be satisfying enough unless you tick that DSEE HX as well.
*****the weak thing***** the lower-mid Get some what veiled....sheesh! It is still there but with less clarity
So the best sounding from the DAP is to combine both "Surround Studio" and DSEE HX. Did I mention it still remain some what artificial ? Luckily the tonal body of instruments remain realistic.
Now, back in stock non-enhanced form, the lower-trebles is weak, and it will be more likely unsatisfying.
This is me being picky like a prick, and speaking honestly from using my brightest and truest headphones MdR-SA5000 modded for the ultimate xperiences.
My ultimate conclusion on the ZX2 ? Sony gimped it overall sound quality down to allow people the ability to hear changes from their so called "cutting edge technology". Is ZX2 an excellent DAP though ? Absolutely ! But Sony need to allow people to utilize the best of the player quality without gimping it.
So my ultimate Resolution :
Go to setting, and disable the Sound-enhancement app. Make sure you use the app before disabling it like ticking DSEE HX and whatever else. Disable it for the best ultimate listening experience, and the truest form of quality from ZX2.
Enjoy guys. Took me 10 months to figure all of this out roflmao. Can't blame me though. I used it with the enhancement app disabled for months, and only recently got back to it a few months ago, did not imedietly notice any big differences until I sat down recently and started to analyze it as I could observe some unsatisfying feelings
Yes
1/ open enhancement app, and tick DSEE HX or whatever options, don't matter. Actually never tick Dynamic Normalizer.
2/ go to setting, then apps
3/ swipe left to the end for the tab "all"
4/ scroll down and look for "sound enhancement" app. Select it, disable
5/ confirm
***if you are listening while disabling the app*** turn your volume down....the sound will be 2-3x louder at the same volume level !! Don't blow your ears drums
I believe I get the best juices and quality from ZX2. Now this is true audio quality, and non of the color, software enhancement craps....won't even be possible to EQ, but I doubt you need it if "true, accuracy, realistic, quality" music is what you are chasing for. Assuming why you buy this ZX2 in the first place
1/ use TRRS connection whenever possible
2/ have to disable "sound enhancement" apps
Please sticky, if someone can
