probably the wrong thread for me to post as I have not really reached a 'verdict' as such -- I am still trying to come to terms with 4.6 NDS update in my active system. A factory reset did have quite a big impact from a brief listen after doing it -- but unfortunately not in the right direction.
Been very busy with work lately -- but I have managed to steal some time to have a listen every now and then. Prior to the upgrade, it was often quite difficult to stop playing music whenever I decided to listen to "just the one" track -- often found myself still playing a couple of hours later -- such was the draw. The few times I have had a chance to listen after the 4.6 upgrade -- this 'draw' has been missing -- meaning that I had difficulty listening for more than 30mins -- lost interest totally after that. Initially I thought this was to do with mood, etc., -- but i now know that is not the case. I tried to force myself to have a longer listening session this afternoon -- failed again. This suggests that in my system -- this upgrade is now working as well a I expected.
It can be quite difficult to describe what one is not happy about in relation to sound quality as this tends to get one dissecting the sound -- which in itself can be quite stressful.
But FWIW, please allow me to try.
- Am I hearing more detail?
Yes... but see next point...
- Then, hey, what are you unhappy about?
The "detail" to me sounds like it is not a 'coherent' as in 4.4 -- the extra "clarity" seems to be coming from exaggerated musical lines -- making the music sound somewhat forced, harsh, congested and fatiguing.
Unless things miraculously improve soon, , It is very likely I will downgrade to 4.4, but I will give it a few more days before doing so.
It is fascinating though that firmware/software can make such a difference -- but I guess that is not surprising in this day of increasingly "processed" music.
