I haven't had time to complete a comprehensive review, but the Rx is in the Head-Fi Summer Gift Guide: http://www.head-fi.org/a/head-fi-buying-guide-portable-amps-dacs-daps-page-2
@Currawong, nice description in the buying guide, echoes what I hear. It also pairs well with the cleaner sounding X5ii.
yes ditto that, very nice write up, your WAY better at it then me, more direct and to a point,
I think this shy wittle unasuming puppy is going to be a GREAT BIG contender! Ken has not just blown this one out of the ballpark, but left it behind in the dust! needless to say I am very very happy with the Rx, and I do enjoy my ear time with the Rx!
the detail, the clearity, the openess, the spaciousness, and the happiness/smile it puts on my face!
tanks, rumble, rumble, rumble, Ken, well they do, lol,
