Leo was the featured guest at an AudioSyndrome meeting at my house about 18 months ago where he demonstrated his first generation amp, DAC and streamer (the Apple series) for the club. Very nice sounding gear. His streamer/DAC combo impressed even our most die hard vinyl guy, who said he thought was "engaging." While this might sound like somewhat faint praise the background story to this is that this was the first time I had ever heard him say something nice about any piece of digital equipment.
And from everything I have heard, the new series of gear sounds even better.
Definitely worth consideration on sound alone, but even more so if space is a consideration for you, as Leo gets great sound out of gear that has a very small footprint.
