Hello everyone,
I recently received the Fiio KA17 and used it with my TGXEar Serratus, but I noticed that the sound was not as loud as I expected. My setup consists of a Samsung S24 phone, Apple Music, and the Fiio KA17 at 50% volume on my phone. Even the sound seemed a bit muffled and not what I have come to expect of the Serratus. I confirmed my doubts when I tried the same setup with my Fiio KA3 and found that it was too loud at 50%, so I had to bring down the volume a notch. The notes were a lot crisper as well on the KA3. In both cases, I used balanced 4.4 output
I tried different settings such as changing the volume to 100/120, changing the filter settings, gain on/off, and desktop mode (which did increase the volume slightly). However, the KA3 seemed to be much better than KA17 for the Serratus. I wonder if there is something I am doing incorrectly.
Also, I noticed that the volume is okay when I use the Fiio JD7 or the Fiio FF3. I updated the firmware to the latest version (v0.99), but it didn't seem to change much.
Any help would be greatly appreciated. Thank you.
