I am curious as the what bit rate you use for you audio tracks with your unit? I ask because I read that DSEE HX requires bit rates of at least 241 kbps or higher to have any affect on sound quality. Below that the quality is to low for it to have any affect. I have had the A17 for over 3 years and played with DSEE HX several times. All of my tracks are either 16 bit flac or 320 kbps AAC or Mp3. With 16 bit flac files I can't hear any difference with DSEE HX on or off and only very minor differences with a few 320 kbps files so I leave it off. As a rule I listen to music with all sound enhancements turned off. Sony's engineers when describing the benefits of DSEE HX use alot of the same verbage describing the benefits of HiRes audio and typically use MP3's when talking about the benefits of using DSEE HX. Since I listen to mostly 16 bit flac I don't really find it makes a difference to me. The areas where we are suppose to hear a difference with DSEE HX are:
Seems to me what Sony describes here could be attributed as much to your choice of headphones as to any real benefit of DSEE HX
- Expansion and depth of the sound field, or in the size of the performance area (such as in large concert halls compared to studios) – you can feel it with the applause of an audience, afterglow of instruments or atmosphere.
- Clarity of the position and separation of each instrument
- Vividness or presence of the performance
Since I don't buy into the HiRes audio hype the idea of DSEE HX improving audio to 24 bit quality is pure marketing hype to me to further the HiRes audio myth. My Sony home receiver has DSEE HX as well and even on my much higher quality home system I find DSEE HX offers no audible benefits for me. I personally would much prefer an Audio Direct feature that bypasses all internal processing vs DSEE HX which supposedly colors the sound to make it sound artificially better.
My Sony receiver has an Audio Direct function as well and to my ears it improves sound quality more than any supposed benefits adding DSEE HX processing to the audio chain does. If Sony is serious about providing the best audio quality from its DAP's then Audio Direct should be an option
Well, I am on head-fi, so of course I have zero low quality files. I have a bunch of mp3s, which I use for burn-in as they use up less battery but all are 320 kbps. Aside from them everything else is in cd quality and above. The DSEE HX does the same thing for mp3 and lossless, so I don't care what the sony engineers say coz it doesn't really do that. As I said it is not a big difference overall but it definitely acts more as an fast roll-off filter rather than a magical hi-res feature. It is easier to hear with stuff like cymball crashes where with DSEE HX on the cymbals have a touch more energy but are cut off earlier while with DSEE HX off the are smoother and extend more. That't the problem - according to sony DSEE HX restores the delicate highs present in uncompressed audio, but with it off the highs are more delicate and extended. Instruments and female vocals just resonate and fade out a lot more naturally without it.
And yeah, I would have also prefered if they had implemented direct audio in the place of that atrocious clear audio+
