When i first received my salks (songtowers, songcenter, songsurrounds) i was using a denon 19.... something or other receiver. I will say that for movies it was more than adequate. As far as power goes, it had enough. However, the quality just wasnt there for music. I had a hunch that these speakers really wanted and deserved better. The denon didnt have preouts so i replaced it with an onkyo that did. I eventually added an external power amp and a preamp w/ pass through for music and am very happy with the results. I actually tried the speakers w/ just the onkyo when i was in between power amps and the differences were noticable. I'm currently using an NAD c270 power amp which can be had for a very inexpensive sum on eBay. Good luck.
