Thank you so much Mr Peabody, that was very informative. Currently, I have a Sony STR DE 897 that can output 110wx7 per channel to drive my front Totem Sttaf and centre Mite T and two small Polk surround speakers. The receiver handles the job adequately and the sound is very clean when I turn up the receiver's volume knob to, say, 48. At 48 the music is pretty loud for me. The sound quality is just amazing and the music just comes alive; the imaging and soundstage are superb. If one day I feel the need to upgrade my receiver, which one would you recommend if my budget is up, say to $800. I listen to music quite a lot and I am not too much into HT. The recommended power for the Totem Sttaf is 20-100W and the frequency response from <39Hz-22kHz, does that mean the receiver's output for each channel should not exceed 100 W per channel? If the output per channel from the receiver is higher than what the speaker can handle, in this case, 100 w per channel, does that mean you risk the chance of damaging the speaker's drivers and tweeters? Or a receiver that can output, say, 130w per channel is better to drive the speakers to get the maximum sound benefit? Thanks for all your valuable advice.
