[QUOTE="Ampdog, post: 70455, member: 144"] Ouch. Apart from what has been stated above, this statement compares apples with ... whatever else. The sensitivity of a loudspeaker has nothing inherently to do with requiring a high current. High output current is needed for those monstrosities with impedances wandering all over the show with frequency, often dropping to regions less that half of specified impedance. It has quite as much to do with the power supply storage capacitor as the current capability of the power transistors. Music begins to sound overloaded when peaks are clipped, which occurs in less than 25% of the usual music time duration. There is thus normally enough time for the storage capacitor to recharge to previous peak value (or one can fit extra capacitors!). I concur that the difference between 30W and 80W (if those figures are real) is hardly enough reason to invest in a different amplifier. [/QUOTE]
