I had the X10 already with Begesterung. but the plastic casing and the fan have tarnished the impression. Now the X30, brushed with a better DAC and aluminum enclosure and fanless. Perfect! Only drawback is the somewhat obscure operating concept (like the X10) and that of the fixed Opt output. But get used to it quickly. Who has a lot of music (800GB) and want to archive and clean encondieren is right here ...
