I own a pair of Swan M200’s (http://www.theaudioinsider.com/cgi-b...er/SWM200.html) hooked up to a Denon AVR-85 through Pre-amp inputs, which is hooked up to my PC sound card through a digital coaxial cable. I have accidentally put these speakers through some abuse: 1. I turned on the radio with the speaker volume at max (not so bad, right?) 2. A stupid bug in WinAmp played a mono mp3 as data. I think this is called a square wave, it’s like playing a data CD (does anyone know what I’m talking about?). Basically the digital signal was never converted to analog before it reached the speaker. How likely is it that my speakers are damaged because of this? They do sound a bit different but that may be just the placebo affect. Is there a way to test them?
