Thank you for your insight. I frequent these message boards and have always found sound advice. I have pushed my reciever (Sony DE-545 100W) on several occasions to it's maximum with my M60's. I didn't hear any type of distortion, however, I will cease pushing my reciever to the max in the future. I DO NOT want to damage my M60's as you can imagine. Hopefully, I have not already damaged my speakers in my ignorance. They still sound as great as they did before.
One more question and then I will keep my big yap shut for a while...Does clipping over time destroy a speaker or can only a few mintutes of clipping destroy a speaker?
