Ditto. Mine arrived from Amazon today with a 44% charge. Updated the firmware, then I put in a SD card with NIN FLAC files and set to Class A, Mid Gain and played on my Noire. Very warm after 5 minutes and after 20 min, can't even hang onto it more that a few seconds. Oh, and that charge 44% charge was down to 5% in 25 min.
I then charged to 90%, let it play again and still got really hot. After 80 min battery was at 5%.
This can't be normal. I'll play with it a for few more days to make sure it doesn't improve and then return to Amazon. Haven't decided if I'll try a same replacement or just refund and buy something else. Seems like most folks are pretty happy with it.
It DOES sound great! But if I put this in my pocket it'll set my pants on fire and not in a fun way.

Thanks for the sharing. Right now i just always use Class AB, Low gain, Volume 60, MSEB turn on. So far the temperatue is ok. I think the culprit is the Class A. To be honest, may be i don't have golden ears, i can't hear any different between Class AB or Class A

The heating issue does seem to render Class A unusable if the device gets so hot after such a short amount of time that the user can't even hold it.

@Joe Bloggs is this something that could potentially be resolved by a FW update?

Well noted.

Any chance that the saved .peq files are already a standard format. The new autoeq site supports quite a few different ones.

From my experience- yesterday again I used Class A for a few hours - indeed you notice that gets hotter (and battery drains faster) - but in my case not to the point to be unable to hold it: might be related with case? I use the leather case which has quite a big vent opening on the back. I normally use Class A when I need a bit more power to drive my 250ohm Beyerdynamic 990.

Mine gets warm, but not hot to the touch. I don’t use a case, and mainly run iems on low gain, class A.

I don’t think so: I’ve cracked the peq format except that it adds some random (?) decimal positions to each value of gain and Q - I tried to take those out leaving only the significant numbers, but gives format import error- so that’s Hiby signature somehow on the peq format.

I wasn't using a case. This may be why more folks haven't had an issue with it. I'm wondering more about the battery when using Class A. Most reviewers state they're getting at least 6 hrs, and more if they use the 3.5 jack. Using the 4.4 balanced (medium gain), around 90 min is my max. I'll do one more test from a full charge and see if I get any better results.

Have you tried editing in such as way as not to change anything (e.g. delete a number then put it back in) then saving, and checked if that still loads? It may be a problem with the file format saved by your editor?

Let me get back to you on this one.

Unfortunately I've been informed by headquarters that this would be a hardware defect.

I've pm'd HiFilife regarding how he may proceed.

I just tested again. Class A + Mid Gain. Man.. every minute, battery drop 1%... and it is really warm to the touch. So unless it can't drive the can, then only turn on.

Where did you buy your unit from?

Hi Joe, from Amazon. Order# 113-1197399-7573807. Only class A is exihbiting this. For Class AB, the device is fine.

No worries Joe… I was just testing

when I was testing it, I was able to edit the PEQ file in a text editor, and I did not have to preserve the same number of digits.
