A:Answer It depends on whether you have the CF1s, CF2s, CF3s or CF4s. The S750H will work with all of them, but you would be underpowering the speakers in all cases. The S750H outputs 75W per channel at 8 ohms, which is what these speakers are rated for. The speakers are all super efficient, (96, 98, 100, 102 dB) so that will help in regard to driving them with less power. I would recommend a higher wattage AVR in order to really drive the speakers and bring out their characteristics. I would look at the X4700H or the X6700H for more power.
