I've not had any problems with OTG with my X5 apart from an increased battery drain.

By firmware I'm referring to the 2nd Gen GUI and general usability. I know this will be subjective, but there have been no comments so far as to whether it is better, worse or similar to original. All I know is it has 5 top-level choices instead of 7.
Edit: the specs from the post above show a digital pot for volume control

I'm pretty sure it's analogue. This from the list of improvements:

"3. All-new independent amplification stage with analogue volume control, increasing audio resolution and enabling feature for native DSD decoding "

Looking at the comparison chart in the link above I'd say it's not the first time I've seen typos from FiiO. Didn't Joe or James already confirm a new analogue volume control?

My recommendation is to charge fully and whenever convenient, and there is no need to discharge the battery fully at any occasion unless you're fussed about calibrating the battery gauge to be accurate to the last 1% (the X5 doesn't even show its battery level in %!)



My years-old E17 is still trucking along like a champ

 


Ok!

But what do you think is the best for longer battery life span, so it may take more charging cycles: charging with lower amperes 0,5A with with longer current time, or higher amperes 2A with shorter current time?

+1, I would be interested to know this.

Volume control in X5II, unlike X5, is implemented (if to follow the specs in X52ndgen--introliterature.doc posted by Joe) via a dedicated digitally controlled chip based on analogue elements-PGA 2311 by Texas instruments: http://www.ti.com/lit/ds/sbos218a/sbos218a.pdf It's called DIGITALLY-CONTROLLED ANALOG VOLUME CONTROL. So, in essence, it's an analog volume control. And there is no need to fear of additional distortion in the circuitry generated by this chip cause it's THD+N are much lower than those actual ones, which you get after the DAC chip, while Dynamic Range and Channel Crosstalk are higher. It's natural, because all such chips are designed to have the minimum impact on the whole circuitry,not to be a bottleneck, thus being ahead in the specs of the other elements.
On the other hand, each element affects the general performance to a certain extent and analog volume control potentiometers are no exception. While they are claimed by some manufacturers to be the "best solutions", they also have their inherent problems (channel imbalance, etc). So, volume knobs are just another option, sometimes more expensive, more stylish (foppish), but not those, which can save the poorly designed DAP from sounding the way it does or those, which make audible difference (if to compare to properly implemented PGA 2311 or similar solutions)

Thanks for the detailed response.

I think it's odd that with the "deep sleep / instant on" feature, there's still a choice to postpone sleep for up to 8 minutes of inactivity. I just set it to the minimum, since that seems like it'd conserve battery life the best. It defaults to 5min or so.

Joe Bloggs - Can you please shed some light on this?

so no mention of  DSD64, DSD128 (.iso&.dsf & .dff); like x3ii

I am not particularly savvy with regard to DSD file types.  I did previously post, and stand by the comment, that the DSD files I played on the evaluation unit sounded terrific.  As if I was in the control room listening to original master tapes.
 
Other than that what would you want to know?

i thought there was an sacd iso function on the x5ii, just as there is on the x3ii.  Fiio own data,  http://m.fiio.net/en/products/41/comparisons makes no mention of it, their mistake i reckon.

Ok. So has anyone as of Yet directly Reviewed and A/B'd the X3ii to the X5ii? From what I've read, I'm still favoring the X3ii especially on a price point v.s. performance scale, until someone changes my mind.
 
My mind, (what's left of it), is a terrible thing to waste.

Yes. If I didn't already own an X5, I think I would be more tempted by the X3ii than the X5ii, whereas the opposite was the case for the original models.

Yes. I currently have both the X1 and X5 original, and for most general listening I actually prefer the Warmer X1 with an amp.

I'll take the X5 SG over the X5 and X3 SG any time

Good to hear you say that, tell us more, any opinions on the X5ii so far have been very few and sketchy?????????
