The more power you can give to a speaker the better they will sound. As long as It's clean power with out clipping the amp. Clipping a amp will blow up any speaker no matter how good it is.
Amplifier power versus maximum speaker input power
What are the ramifications of using an amplifier that exceeds the maximum input power handling rating of a speaker? I am thinking of getting a pair of Reference 3A Dulcets -- rated at a max of 100Watts RMS into 6ohms -- yet our Threshold S/500 II puts out 250Watts at 8ohms. I normally do not listen at more than 90db. Thank you for your input.
