I have bought the FiiO FA15 in January On and Off... But I have a slight problem... It often just switches off when using it on my phone. My setup is KA15 + Meze Audio Alba + OnePlus 13... idk if its the cable, my IEM or whatever, but it doesn't seem that it wants to work with me.. Has anyone had a similar problem, because I do want to use it daily since it is my first portable DAC-Amp.. Thanks in advance👍🏻🫶🏻
