Hi guys. Really in a dilemma here. I've been searching for a pair of Q900 or Q700 on the used market for a few months now. However, just today I've come across a pair of very reasonably priced iQ90 speakers for about $250 Canadian. This is probably 1/4 of the price of a used Q900 here. I know they are totally different speakers. And coming from a pair of Polk Audio Monitor 70 speakers, I know either pair will be a significant improvement. But do you guys think that Q900 is that much better than the iQ90 to justify my continued search for it, and the 4 times price point? What might you do in my situation? Thanks a lot.
