Calling all users who have previous reported that their AK380 has been stuck in balanced mode. My AK380 got stuck in balanced mode again yesterday after being fine for two months, I have sent an email to AK staff, and will include it below so others can know the details and previous developments of this issue. If you have suffered / are suffering from this problem, I urge you to voice out to AK so they would be more inclined to fix this, if more customers voice out to them.
"To whom it may concern,
My AK380 on firmware 1.24 was stuck in balanced mode in April, in which I have emailed AK support and Kai told me to RMA my AK380 to him for repair. The shop I bought the AK380 from fixed the problem by inserting both 3.5mm and 2.5mm male jacks into the player and unplugging both at the same time, making the 'BAL' on the status bar go away and I can use the 3.5mm output again.
Since yesterday, my AK380 has been stuck in balanced mode again after inserting Layla's 2.5mm jack. I now can't listen to any music with the 3.5mm jack.
This is a well known problem and many users on the Head Fi AK380 thread have reported it, with AK offering no solution except RMA, for 3 months.
Please note that RMA is undesirable because:
1) ECT, the distributor for AK products in Hong Kong, is only opened on Monday to Friday during normal working hours;
2) It takes an extremely long time to RMA the unit back to AK in Korea, and my shop fixing it by the method mentioned above proved that this is not a hardware problem and can be fixed by firmware update.
It is unreasonable that since the problem has been persisting for 3 months, with AK's knowledge of both the problem and solutions that have worked, that AK has still not addressed the problem by a simple OTA firmware update, instead requiring users to take leave off work and give up their player for weeks for something that does not require a repair on hardware. This robs us of our ownership of a USD $3700 device and wastes our warranty period for a RMA that is not required in the first place.
I was a previous owner of the AK120II, and I know that the 2nd generation of AK players had a settings option of switching between balanced and unbalanced mode manually. If you are unable to fix the auto detection of balanced / unbalanced on the AK380, please bring back this setting via firmware update so at least a very basic functionality of the player is not disabled.
I look forward to your reply."
