 The DX50 has a smooth and dark signature, and it sounds very refined.

What? I don't think the dx50 is very bright, but I wouldn't call it dark.

.....my 5th batch '50 can kick your 4th batches ass!  

How did he receive, review, and update a website (but only after having several customers in the store listen to it) all on a unit that shipped yesterday?  Maybe I'm missing something here, but it doesn't seem likely that he is referring to a 5th batch DX50.

well, that is if you can believe everything from any website.... 

 

 
Mike's reviews are quite impartial though, he is a retailer for Astell&Kern and iBasso and he didn't pull any punches on either. Not a flattering review on the AK100 as well.
And since he has the resources to compare several units from each batches, it doesn't look that farfetched... besides, QC in China has a habit of being inconsistent =D
now if only there are others here who also bought from different batches, would like to see if there are any other differences.
 

  that's god damn terrible. although the soundstage is really good on mine, I'd hate to learn newer ones are improved :|

 
which batch were u in? the review did say the newer batch soundstage might be better than the AK100... so would you say the same for your unit?

This is interesting... from Headfonia...

Apparently the 5th batch has significantly more spacious and open sound compared to the 4th batch.. I'm curious on the difference between the 1st and 5th batch now

Any unit can be built within a specific tolerance range say 5% just as an example. As such every unit is unique to achieve the exact same composition in every dap would require extremely precise equipment which will still be within a tolerance level, might be higher for this case but will never be perfect. Now, I am pretty sure if you pull one unit of every batch, you won't be able to tell from which one it is coming from. So I would not worry about that at all, pretty sure iBasso manufacturing tolerance to be quite acceptable.

Mine is from the 2nd batch but I wouldn't know - I don't have or heard AK100...

Maybe I should buy one from each batch.  Since they all sound so different I could label them and then choose the right one for my IEM's and of course, as  mentioned in the review, the sound source.  
 
If I really needed to tweak the sound I could try one of 10 different batteries, the final adjustment could be made by switching out and testing 5 or 6 IEM cable sets along with 7 separate ear tip foam densities.
 
Once I got done with my TF10s then I could follow the same procedure to optimize the sound using each model headphone that I own....
 
:reality mode on:
 
I call BS and if someone can reliably ID iBasso DX50s produced in various batches, doing bona fide ABX testing, I would be willing to award a prize.
 
This is a hobby, but at times it seems hard to distinguish it from a pathologic OCD ritual.

it's possible for QC issues to differ for different batches.
 
on a side note, yes besides changing battery for the DX50 did you know if you paint/dye it in gold you get a richer and deeper sound? paint it in blue and you get a more airy and wider signature while painting it in red gives it a more aggressive and punchier sound...

Paint it in brown and you get a s***ty sound I guess.

Red Pico Slim from Headamp. The interconnect is my own creation; 90 degree gold plated connectors with silver/gold signal wires and copper return wire.

Thank you.
 
The Pico Slim is VERY small... I had no idea. Good to know.

Nice job on the cable. Pretty compact portable rig.

lol, and to think the brown would actually look classy on the DX50... classy piece of s**t

I think you are referring to the Apple iPhone 5S, the gold sounds so much better compared to the silver or black.

Thanks, the Pico Slim is the only amp I feel it's not bulking up the rig, mind you using the DX50 alone is another option. I find the slim almost like a work of art, so tiny, work well and looks damn good. The case is so precisely cut, it's a beauty.

Reporting about the hiss: 
I just received my BA4f cIEMs from cosmic ears, and there is hiss. It's not as bad as with the hisoundaudio rocoo p dap, but it's noticeable. What's quite strange, and I've read this before, but the hiss significantly reduces when I put the gain on high! So the hiss might get less with better firmware? Maybe?
 
Anyway, I haven't tested this setup in bed just yet, so I can't really comment on how bad the hiss really is. It certainly isn't very noticeable on high volumes (with music playing that is).

This is the best sounding 50 period.......end of discussion.
