The Alchemy Stereo/Mono Amplifier
The Alchemy DPA-2 Power Amplifier is about dynamic musicality, thanks to design that combines Class A circuit topology composed of discrete FETs and a linear power supply using a toroidal transformer. The pure analog input stage preserves all the detail and nuance of the most delicate passages. The Class D output stage with switching power supply results in impressive output combined with cool-running efficiency.
The power output of the DPA-2 isn’t just formidable, it’s easily configurable for the needs of every system. Producing 325 watts-per-channel in stereo, the Alchemy amplifier can be easily switched to deliver 650 watts in monaural mode, sufficient to drive the most demanding, power-hungry loudspeakers.
