This is a high quality component with superb build quality. Sure it costs a bit more than the entry level $129 units, but you get a build quality that comes from quality design and manufacturing. You get Swiss made Elna switcher, and Alps volume pots. Also 2 sets of RCA jacks so you can bi amp or run low level signal to a subwoofer.
