This sounds so good that it's insane. It shouldn't surprise that the amp built into a $230 DAP cannot compete with Jan' Meier's top of line stand-alone amp. The DX50's amp really isn't bad but the difference in sound quality is not subtle. I can easily point to the much fuller and better controlled bass but the improvement is apparent across all frequencies, and in the detail and timbre. To iBasso's credit, the DX50 has an excellent line out. It is a very good DAP for the money but it is also, without qualifier, a truly fine portable source.
