I've been searching for a DAP for home use and have not fond anything that fits what I'm looking for. I want something to replace my PC that will play high res files. My Onkyo DP-X1 does have a line out but isn't designed to drive a preamp or amp. The manual warns that running it into a high impaedance (above 600 ohms I think) may damage it. I've tried it anyway and it sounds pretty crappy into a Schitt Moljinar/Sennheiser HD800 combination compared to my laptop. Other than it isn't going to last I can't really complain about the PC but What I want is something that will still be working in 20 years. What do you like?
