The difference between triode and ultralinear is not going to be enuf, I think, to protect your speakers when your blasting away. Depending on your stuff the difference might be only about 3db. Save your speakers, your ears, and your neighbor's good will - keep the volume down. :-)
How does a speaker blow out?
I don't understand how a speaker "blows" if the wattage of the amplifier is less than the upper limit of the speaker's limit. Then again, I guess I don't really understand what "clipping" is. The amp is 22w, I was listening at a moderately high level, there was a bass heavy section in the music, and then I heard the most painful noise coming from one the of woofers. Sad.
