HM-801 with balanced module can output both balanced and single-ended. since i don't have a balanced cable for Miracle, i am actually using the single-ended output.
We all know that BA IEM tends to sound analytical and cold. Straight out of iPhone Miracle does have a digital sound. 801+balanced module with its warm and analogue sound is just a perfect match for Miracle, at least in my mind. :-)
801 actually uses probably THE best sounding D/A chip PCM1704UK. Once you pair it with Miracle which has a very neutral sound, the music sounds just SO real. Every headfier should at least hear a PCM1704UK DAC once in their life. It's a shame that no one is making a chip like that. :-)
