Ok cool,I'll give it a shot. My zx300 doesnt do analog line out either, bht it's not terrible double amping, not ideal at all but oh well, cant have everything right? I'll be really excited if this sounds good enough on my ex1000 to let me sell my zx300, so I can buy other in ears. From what ive gathered theyre quite different, this being a sabre dac and all, and the amp not being great, but its a phone. I'm just excited about this phone in general, its better than the galaxy s7 active I had as far as just normal use goes.
