If i buy the DAC, can i just... Replace the ES9023 DAC on my z1 into AK4493?? Would it be a good idea? Or will it just gonna destroy my z1 entirely? If it's a good idea, then how to change it? I'm not an IT guy. But i know someone who is. Is it just like soldering-kinda thing and then play, or i should mess with the z1 motherboard and everything as well?
