I really don't know why folks do not try previous fw if they seriously care about sq. It is obviously that v1.10 file is bigger regardless of less fuctions than newer versions. And bigger for what if not for sq. Times when careless programmer made mistakes passed long ago.
Bigger is
not better. In fact, it's often
worse - means there's more bloat, poor compression or coding practises going on.
Armchair programmers and engineers are my favourite type of people on the net.
My ZX300 started on v1.10 before upgrading to v2.0. The differences:
v1.10 kept crashing whenever I played with playlists
No support for the BT receiver
When I upgraded to v2.0, I honestly for a second thought that the highs sounded more sparkly. Then I went back to a store with a v1.10 ZX300, then realised I was just imagining things.
Gotcha!
Although, can a clean voltage have any bearing on the quality of bass (well defined?) as Sony claims?
Sure, but if it's dirty voltage, it'll affect a whole lot more than the quality of bass. Usually, when people talk about powerful bass, it's because there's sufficient current or power, not voltage.
About the hiss on the 3.5mm, it still bugs me how the gimped out jack produces it, compared to the 4.4mm for you.
Never experienced it on any phones I used though.
It'd be well funny if one of your co-workers got themselves a DAP with 4.4mm to use that beauty of an earphone
Although most people think I'm mental for using a dedicated source, leave alone one that costs $600, so you're probably safe. Ain't for the common man et al.
I'm just nitpicking it because I was very surprised at that revelation. The only time I noticed it was in the dead of night in my room, just about to nod off and sleep. Otherwise, I never noticed the hiss. In terms of hissiness, this is much less than the Fiio DAPs, so if you're sensitive about it, just try it out.
For the record, the IER-M9 only hissed from my computer output (unsurprising). Not even a crappy phone hissed on the M9s.
