Damned if I can explain it.
Yeah, I know. I have seen all the frequency graphs and they say it doesn't exist. But I have started using the headphone out instead of the line out. Unfortunately I bought it because of the line out.
I am using mine a little differently than everyone else. I wanted to get a standalone unit for playing all my FLACS with my home system. But those units were much more expensive. I also didn't want
to have a computer sitting next to my system to do this. So this looked like a killer deal for me. My files play fine, no gapless issues (so far), no freezing issues (again, so far) but the line out seems so muddy.
I can live with using the headphone out. It allows me to use the bass control to clear up the sound a bit. My firmware update wish would be a 10 band eq (para would be awesome) and USB OTG so I can hook up a hard drive.
