So couldn't resist the temptation of the QS10. Have not gone into the realm of QS speakers yet, Using M3 and M22 so far.
Currently using my M3 as height and 22 as sides. Fronted by M80 and a VP160, powered by 3 channel ADA1250/ EP500.

So Would the QS10 be better as a side rear or a front height?
Currently have couch against the wall as to why my M3 are in front, plus the front stage is huge. Though I suspect the QS will be more forgiving with the being so close to the wall for rear placement.

I also ordered a set of the F.M.B. so have to decide on M3 or M22 for the other placement with the F.M.B.

Thanx in advance for your thoughts
