... and, of course, how load it is depends not only on the amplifier power but also on the sensitivity of the loudspeakers. My (old but wonderful) Tannoy Berkeleys are very sensitive and at anywhere near their maximum handling capacity of 85 watts are absolutely deafening.
85 watts into more modern, compact (but much less sensitive) speakers won't be nearly so loud. (that's all RMS watts by the way)
