Confused here: How can changing a battery alter the sound of the DAP if it's, well, just a battery. Does one get "better" light if changing batteries in a flashlight? If possible, please explain with more than, "I hear it."

I think you're all nuts.The only way to improve the sound is to paint it pink

Hmmm...or not, 'Made in Japan' batteries are probably better, you know.....the kind you don't have...:(

lol.  really.

So spent the last twenty minutes comparing various 10 second clips and doing a quick battery swap. I had the cover off the whole time, using my hand to hold the battery in place, using the IE800.

 

My conclusion: I just wasted 20 minutes of my life. Anker battery sounds a little better than the Samsung. The difference is really slight. I would say the Samsung sounds a little thinner and airier, but at the same time sounds more diffussed and veiled. The Anker sounds more full also sounds more focused while the Samsung is just a little bit more hazy.

 

The difference is really really small. It took a lot of tries, repeated over and over again on various clips.

 

But yeah, for those of you with Anker batteries I'd say don't waste your time. I haven't done the stock battery yet. I'll get to that when I have time.

thanks. i had just received and finished charging 2 anker batteries.  but i can't even tell if you're joking.  

 

otoh, people here will swear that a $400 cable makes something sound different, so who am i to judge?

Indeed. The sound is a quite resonant (good extension) "ka-ching" from the cable makers' cash registers.

Well, back to batteries in the IBasso. (I'm auditioning the 50 first to see what the fuss is all about.)

Theoretically the DX90 should sound better with battery of lowest internal resistance. This parameter will directly affect the HO total impedance. So far I have not seen any measurements of battery resistance in this thread though.

Just my opinion but if you can't hear a difference in patch chords or headphone cables, they're the least of your system problems and obviously don't warrant the cost.

Equipment to measure the ESR is something not too many have. I have the equipment but it is in storage 1000's of miles away. Maybe someone can do it. Good equipment to do this is expensive.

What is the equipment?

 A Sencore. I don't remember the model. It was pretty expensive when I bought it but hand, at times.

Hi,
We will release a new USB DAC driver within this week.
It has the 64bit driver. But you have to turn off the digital signature before install it.

Sincerely
iBasso Audio


Hopefully we get it soon smily_headphones1.gif

At almost 0 impedance for HO with the stock battery? I doubt you can hear any difference if you go any further.

It is the possible lower impedance of the supply battery to the board that would be the factor, IMO. This would increase the dynamics and depending on how clean the DC is, things like transparency and frequencies. This is how it affected systems I have built, as I lowered the impedance to the various components. There are many variables though it seems, and this is conjecture, the main two are chemical combination and interaction and ESR, with regards to possible battery influence.

It sounds like you are trying to pitch something, and I don't buy it.  

 

Anyhow, the impedance affect the current supplied to the circuits do to the impedance inside the battery.  As the battery starts to degrade, impedance rises, and thus provide less voltage because of the voltage drop of the internal resistance.  Circuit have something called a regulator that keeps the DC level in the level that the circuits need, if it wasn't stable those ICs would be screwed up, so have some faith the regulator is doing it's job keeping the DC level stable.  At a certain voltage level, the regular cannot do it's job, and time for a new battery.  Possibly batteries have an IC inside that kills it if it cannot provide enough for the regulator.
