All headphone outputs are, well, headphone outputs.

The internal circuit of the S9C Pro is balanced, so it will sound the best from the balanced headphone output.

Can't phrase it simpler than that.

Do i need to mute or turn off the Aune s9c Pro before unplugging the headphones to avoid any risk of ruining the headphones or the Aune s9c Pro? Some people say remove the headphones before turning dac/amp off and some say turn off or mute the dac/amp before unplugging/plugging headphones.

Maybe Aune s9c Pro has some special safety features for this?

Thanks
