We cover 55
amplifiers rated
over 180 watts into 8 ohms
(185W to 1170W).
The high-power end: large rooms, low-sensitivity or low-impedance speakers, and headroom you will mostly never use - which is rather the point of headroom.
Watts are the most over-read number in
audio. Doubling the power buys about 3dB, and a speaker 3dB more sensitive buys
you exactly the same thing for free. Before shopping by wattage, try
the amp and
speaker matcher to see what your speakers and room actually need.
