I am about to upgrade my system. A salesperson at a very respected audiophile store is recommending me an amplifier that has only 3/4 the nominal power compared to that of the speakers that I am looking at. He says that as long as I don't intend to play at crazy levels, it won't be a problem. Is he correct?
Everywhere I turn for advice, I am presented with the rule of thumb 2:1 ratio (amp:speakers) for nominal power, with warnings that a too weak an amplifier might damage the speakers. (The amp/speaker combo I'm being recommended roughly has a 3:4 ratio)
My question is this:
Does the 2:1 power ratio apply only at amp clipping levels? Or is important also when playing at moderate levels?
