There isn't one as AK officially and intentionally does not maintain a public one, and I highly suggest not to maintain an open resource ourselves - in case AK finds out, I'm not sure if we will be able to get firmwares from them anymore.

  Though after more listening, 1.25's SQ is muddy and less dynamic comparing to 1.23. Back to latter version. I wonder if there will ever be another version that can beat it or at least meet it eye to eye.

On the contrary I find 1.25 obviously thicker, less crisp, and heavier bass. In fact the whole SQ sounds "heavier", if that makes sense.   That's just very initial impression though, need to listen more later to make a better verdict.

  Not sure why it's in question form but yes, exactly as AnakChan said. Thought everyone here knew this already.   Amp's battery does gown down slower than the player's in my case too but 100% vs 50% is definitely exaggerating. When both start from 100%, battery level difference between the...

      If it's a discussion between existing users I wouldn't bother to join because the argument between regular AK380 and CU is getting old and extremely repetitive, but for a potential new owner who has similar concerns as I do (color and weight) then I should voice up here: yes, there...

  I can smell the word "sublime" coming this way. AK should totally make a rainbow version and it will have the best of everything.

  HKD6,280 for the recorder. No set price yet for the mic kit, which is the one I got my eyes on.

      It says you can pre-order now and the item is scheduled on be on sale before mid-April. Price with tax included, shipping cost is nil (implies local of course). 2 years warranty. Gotta say 24800yen is a very steep price.

  They actually got that written out in sensible English on their website:   "Currently, e☆earphone does not ship our goods abroad. If you want,please use forwarding service agency.  In that case, the payment method is limited to credit card payment. The performance guarantee is...

      You guys are lucky. I got it at $89.99 and back then it was already a good deal, but $79.99 right now is ok too.

  Amazon is selling SanDisk's at $79.99 though.

  I'm not sure what's going on with other AK380s here but mine definitely lasts more than that playing 16/44 FLACs - 5 hours means 20% per hour and I'm sure mine doesn't go down that fast. Maybe I will test run it from 100% to 0% sometime and see exactly how long.   For the AK ripper, if only...

      Yes I got the file, which allows you downgrading it yourself. I was asked not to share so unfortunately I cannot post it here.

Just downgraded to 1.23 and compared the few selected songs I listened to right before downgrading. I recall when I upgraded from 1.19 to 1.23, I was wow'ed by the SQ of 1.23; after listening to 1.24 for two days and now listen to 1.23 again, I can't believe I got wow'ed again - 1.23 is just...

  That has already been asked and answered at a AK gathering - change in SQ is not intentional as they do not tune it, but they acknowledge that somehow SQ changes in different versions.   I do prefer 1.24 but I will downgrade to 1.23 later to do another comparison for confirming my preference.

  "Improved Operation Stability", that's it.

  That's the Copper combo - copper version for both the player and amp if you're not aware of it.   Had a few minutes of listening of 1.24. Bass seems to be slightly tighter, overall pretty pleasant listening experience. Definitely not the revolutionary difference like from 1.19 to 1.23, but...

  You are trying to be funny but LA was actually serious about it.   I'm sure if you take AK380 to outer space for listening, it will start suffocating and choking on its sound output.

  I would actually recommend dynamic IEMs rather than BA ones for those genres you mentioned (except female voices), such as IE800.

  Are you talking about 1.23 original vs 1.23 Cu? Because 1.23 is likely to change the whole story.

  It's definitely not the case of "I press the button and oh I hear the difference". You have to listen to a whole song with Pro EQ off, then try it all over again with it on. The difference is subtle, but for bass-centric cables Pro EQ can bring out the main theme just that slightly a bit more...

  The whole SQ has changed regardless of EQ on or off. After playing around with 1.23 I still prefer with Pro EQ on for bass-centric cables like PEM22

  Hi speed, just grab it. Reminds me of the energizer bunny ad that how the bunny was all lethargic and became hyper after putting in energizer batteries; 1.23 is like the energizer batteries. Music is really powerful now (not driving power) even on low gain. 1.23 trumps previous versions by...

With all the comments on 1.23 looks like I do not need to advocate for SQ change this time Now I'm curious how regular AK380 compares to Cu under 1.23.   Re 1TB micro SD card, it's like someone selling you plane ticket to Mars - anyone who pays attention to technology news would know it's...
