I have 3 Chane 752 speakers. 2 Klipsch 600 II. 2 sonance ceiling speakers.... Old Yamaha Advantage 1040. My problem not enough power to drive the Changes 752... Looking for new, any suggestions...
Your AVR should have no problem driving those speakers since the Chane specs show 91dB/1W input sensitivity. Check the speaker levels, especially if you recently bought these. Did you run YPAO? You can raise the levels of each speaker easily, but I would do the setup on a computer, not with the remote (it's a pain).
With the AVR connected to your network (I always recommend using an ethernet cable instead of WiFi), find its IP address, open the browser on your computer and enter the address (non-Apple router would have a 192.168.xxx.xxx address) and add '/setup', so it will be 192.168.x.xxx/setup and it will give you much better and faster control of every setting.
