Assuming you have good speakers of average sensitivity, how much amplifier power is necessary for good imaging and dynamics?

Stereophile Staff's picture
Audio amplifiers are now available in power ratings of as low as a few watts. At the other end of the scale are gigawatt amps of 1000W or more. Most fall somewhere in the middle. How much power does a good system really need?
