Yeap me too but apart from relatively new interface I don't see much of improvement regarding KA3!
At least before the app didn't recognize any changes made to filters, gain, etc. hope they fix it now!
Also, those filters don't make any changes to the sound at least to my years (definitely not like in BTR5, which is noticeable)

Low pass filters make barely noticeable changes if any.
They are applied to the time domain and you have to listen very carefully to tell them apart.

Anyone have success connecting to an iOS device with Fiio lt-tc1? Only my BTR5 2021 works with the IOS device running 12.5.5. I hear no sound from connected IEM on the KA3.

Obviously no problems on Android etc.

[FiiO]

The new firmware V2.0 for FiiO KA3 is now available!

Updated on 2022-01-24

Changes and improvements about new firmware are as follows :

1.Added memory function for turning indicator light off; (You could switch indicator light option between Turn off(until device restart) and Turn off(always) via Android version FiiO Control APP. Turn off(until device restart):Turn off the indicator light for now and turn it on again after the device restarts; Turn off(always): Keep turning off the indicator light until the setting changes.)

2.Added dynamic power policy adjustment function; (With this enabled,the system will dynamically adjust the power policy according to the playback sampling rates,so when playing tracks with lower sampling rates, the power consumption and heat generation will be effectively reduced.

3.Added hardware mute switch function; (The device is embedded with a hardware mute switch, which can mute the impulsive sound that occurs when switching between tracks of different sampling rates. However, when the mute switch functions,it will also make a slight pop sound. You may choose to enable or disable it according to your preference.)

Note: Please update the APP to latest version in order to use this new functions in KA3(FiiO Control APP V2.8/FiiO Music APP V3.0.9)
