Recent decades have seen concerted efforts by audio manufacturers to encourage a shift away from high-power Class A amplification in favour of newer, more “efficient” topologies with claims that they can deliver the same level of performance in a lighter, more compact and decorator-friendly form factor.
The truth behind these specious allegations and the true motivation behind the promotion of lightweight amplification are very straightforward. It is an elementary exercise in cost cutting.
As material costs (copper and steel in particular) skyrocket, designers under the “guidance” of corporate accountants have been skimping on the costly massive power transformers and banks of high-current capacitors that generate the reservoir of electrical power that ultimately becomes the audio signal that drives your loudspeakers.
But it is the size and quality of these components that directly determine the amplifier’s performance potential. Heavily regulated, stiff power supply voltages and high current capability are crucial to achieving the control and speed that translate into musical clarity and resolution.
Despite bold claims, the audio industry has not found a better way to do it, just cheaper ways to almost do it.
Unlike so many current models crippled by downsized power supplies and capacitor banks as designers struggle to mitigate the impact of ever-rising raw material costs, the Gryphon Antileon EVO employs pure Class A bias with full power instantaneously available at all times, regardless of the actual load.
TRUE, PURE CLASS A requires heavy transformers, substantial capacitor banks, high electrical consumption, lots of heat, massive heatsinks and very, very expensive parts and manufacturing.
There is no shortcut to the sheer magic of pure Class A.
