EDIT: Jim In my opinion, for a digital source, if you want value and convenience buy a Mojo 2. Amazing sound and portability, I use it on one of my home Marantz/dynaudio systems, my $10k car system and to drive audeze lcdxc and lcd4. The Qutest is better but not worth the extra cash.............. well MAYBE except listening through a Sparko Aries or a Burson Conductor 3x driving Audeze LCD4 or something like my Musical fidelity nuvista preamp feeding a rotel RB1080 and top end dali speakers
