High-end-audio manufacturers are both more and less adventurous than their more mainstream contemporaries. While mainstream-audio manufacturers will almost invariably change their models every year, the changes are more often than not cosmetic—at least in between successive models. High-end manufacturers, on the other hand, will keep the same model in the line for several years, but make cosmetically invisible refinements along the way.

For many audiophiles, choosing a power amplifier is a vexing problem. Just how much must one spend to get true high-end sound and a solid build quality? How much power is really needed? And what amplifiers are suitable for driving low-impedance loudspeakers?
