Just don't turn up the volume to distortion levels. It's better to have a receiver with more power so that you won't be pushing it into a volume that will see any distortion. You can run paper speakers with your amp if you simply listen at lower levels.
I recently purchased a JBL S300 7.1 Speakers and I have ordered Pioneer vsx1015 Receiver. I took Pioneer vsx1015 Receiver, since I got a good deal and its THX certified.
The JBL S300 manual says the recommended maximum power is 100W, where as the Pioneer's specification shows (http://www.pioneeraus.com.au/home_entertainment/receivers/vsx1015/index.html#anch_11) that the output would be 180W (6 ohm ).
Will the receiver blow my speakers? ...
Pls. advice me on this.
