I have the 5's (six), sc9 and sc6 together with the sm6.I use the 5's to drive proac tablettes and doublettes. I keep two of the six for backups. I pull the lows off through a dual subs before sending the final signal to the speakers. Sounds great. I use the sm6 to drive rear channel in HT set up. As you may know a pair of 5's recently went for $650 on ebay. Hang on to them. I don't think with the right speaker match then can be beat. Let me know what interconnects/speaker wire you use. I've not done too much in that area.
