I have just discovered that my Moviestar 100's have been putting my Yamaha RX-V373 into power protect mode and will have to be replaced. I was sold the whole package from HN and was assured that they would work fine together but after a second trip to the repair shop the tech pointed out that the Moviestars are 4 Ohm and the receiver is only rated to 6 Ohm. I didn't know enough about impedance to check for this first but HN have been good and will replace the speakers/receiver to something suitable.The easiest solution seems to be to replace the speakers but my wife really likes the shape and size of them so I am reluctant to swap them. I would be prepared to upgrade the receiver though. Having a look around I see the Yamaha RX-V673 is good and has this in the specs7-channel 1,050W = 150W x 7 (4 ohms, 1 kHz, 0.9 % THD, 1 ch driven)630W = 90W x 7 (8 ohms, 20 Hz-20 kHz, 0.09 % THD, 2 ch driven)Does that mean that it would be suitable for these speakers? What does it mean by "1 ch or 2 ch driven"?If anyone can point me towards any other receivers in the $1000-$1200 range that would be awesome.
