This top-end amplifier proves that high power does not have to mean a large, heavy design. Although this amplifier is highly efficient (and thus compact), its specifications easily surpass those of quite a few conventional designs. If we’ve given you the idea that the fully assembled amplifier is as light as a feather, perhaps we should qualify our statement somewhat. After all, 2 3 300 watts of true power naturally requires a rather substantial power supply. But that’s the only aspect of this amplifier that is comparable to other types of amplifiers. Thanks to clever use of pulse-width modulation, this amplifier is so efficient that a heat sink with quite modest dimensions can be used, which means that the enclosure can also be kept relatively small.
