There is a real explanation for that: When a transistor reaches the ceiling, it hits the ceiling very hard. The signal peak is clipped, as if the peak of the signal curve was cut off with a knife. That gives an extremely nasty kind of distortion (which is nothing like the dynamic compression that some people refer to as "clipping"). Tube amps doesn't have any such hard ceiling: They may be unable to bring the signal curve to its very top, but first: It can for (very) short periods go way above the rated effect, and second: Even though lower than idea, the curve form resembles the ideal curve quite well.

The answer to this problem: When buying a transistor amp, select one which has at least ten times the output power you will normally need. Now, five watts gives you a lot of sound from most HiFi-class speakers, so fifty watts is plenty for most living rooms. But if you regularly turn up you amp to more than -20 dB (assuming that you have a volume knob graded in dB, with 0 dB as max), you need a bigger amp.

Another thing that is rarely discussed: Even a tube amp can deliver those peaks only if it can draw the power from somewhere. In the old days, the power supply transformer held signifiant energy as an electromagnetic field in the coils and transformer core, and a brief sound burst could tap this energy. Some amps had power supplies designed explicitly for building up an energy reserve: When the amp was switched on, you should let the power supply "charge" for maybe half a minute before playing loud music. Modern, switched power supplies have no such energy storage, unless they are equipped with huge capacitors solely for this purpose (which some of them have).

Again: If you have an amp designed to deliver 10 dB more than you will ever want to listen to, you will not risk emptying the reserve power stores. You do not need the power to play loud (even though some HiFi-freaks use it for that...) but to have power for the peaks when playing at more normal levels.
