Hi. I have been using an Onkyo DP X1 for years. It’s an outstanding player. I wouldn’t consider another player except that battery standby time is about 3 days. When you recharge and it reboots, you lose your playlist entries. Also, with 18000 songs it takes half a day for the library to register.
what kind of standby time does this machine have? The FiiO M11, for example, lasts almost a month on standby.
