I have a Qutest and auditioned the Hugo TT2 at home in my system for a week.
The TT2 was a noticable step up in almost every aspect - greater extention on bass and treble, instruments and vocals had more body and texture, and soundstage was wider. I think it was slightly more forward sounding in my system as well compared to Qutest.
Switching back to the Qutest, on the first day, the music sounded more constrained but as my ears adjusted, everything sounds great and I don't miss the TT2.
I might still upgrade to the TT2 in a few months :)
