The drawback I had with high power amplifiers driving efficient speakers is that I couldn't bring my volume control much past 9:00 on the dial. This is not a good idea since most pre amps sound better if more of the volume dial is used.
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.
