If you add up what a decent preamp will cost as well as an external DAC then it is good buy, if a little painful when handing over the £400. The Mojo is a remarkable bit of kit, makes music. Doesn't seem to change in sound terms whether plugged into charge or left on battery power either - I use a LPS to do this which might be OTT. BTW I got the very nice case thrown in for that, Frank Harvey Hi-Fi - it's normally £60!
