I have Mojo 1, Mojo 2 and Hugo 2 (and the 2Qute in my Stereo, which is a Hugo 1 with fixed output)
You should try the Hugo 2 if you can. Better definition and detail than the Mojo 1, especially in the bass (deeper, more detailed, textured and authoritative) and the treble (also more detailed, textured and extended). Overall extremely even, detailed and textured from deep bass to high treble (as far as I can judge with my hearing limit of 14,5kHz....)
The special thing about the Hugo is the staging, imaging, layering and depth are really good, and there's so much detail that you can hear the room reflections in the reverb of the notes.
Mojo 2 is right in between - it has the flat frequency extension top and bottom of the Hugo 2, and in terms of detail, precision, soundstage width and depth, imaging, separation and layering it's somwhere in the middle betweem the Mojo 1 and Hugo 2. But it does not have that magic "room acoustic" of the Hugo 2. It's more like the note starts, then decays in a straight line while on the Hugo 2 the attack is sharper and the decay comes alive with lots of nuances and microdetails.
