So, some early impressions on the QT5s:
Interesting sound, spacious and good stage in width, height and depth.
I expected them to sound a bit warmer, but they have sufficient bass impact and a real good extention in that department.
Some described them to be slightly mid-centric and I can definitely see why that is. Works quite well with vocals of all kind.
I had the Shockwave 3 at my place for a while and I can definitely see some comparisions, although I feel like that the SW3 was bassier and way more aggressive on the treble.
Speaking of which the QT5 OOTB has a really well extended treble-response, but no fatigue thus far.
QT5 is one of the more balanced offerings I purchased over the recent months. Not overly thick as I'd imagined them to be.
