Enormous Power, Natural Musicality, Highly Resolved Sound, and Tremendous Efficiency: Compact Audio Alchemy DPA-1M Mono Power Amplifier Outputs 325Wpc and Drives Practically Any Speaker

The power-output numbers associated with the Audio Alchemy DPA-1M mono power amplifier alone boggle the mind: 325 watts per channel into 8 ohms, all from a device that is just 10.5 inches wide and 16 pounds. But the technical specs pale in comparison to the tremendously musical sound and highly resolved character. With DPA-1M, you'll experience reference-quality rhythmic drive, expansive soundstaging, authoritative bottom-end presence, three-dimensional definition, full-bodied tones, intimate nuances, and fast transients. You'll become more emotionally connected to your favorite artists, and never again want for more power. Combining a Class A analog input stage with a high-efficiency Class D output stage, DPA-1M operates equally well on the floor, on an amp stand, or in a very tight space. A price-to-performance bellwether, this Peter Madnick-designed and U.S.A.-made component manages to give you the best of all worlds without the traditional shortcomings of Class D designs and with all the fun, grip, and involvement you expect from high-end instruments.

"Both the stereo and the mono versions of this amplifier sounded like indefatigable powerhouses, with plenty of dynamic headroom. I never heard the amplifier soften the bass, harden textures, or congeal the soundstage, no matter what the playback level or how demanding the music."
– Robert Harley, The Absolute Sound

The aesthetically clean DPA-1M runs cool at 80% efficiency and consumes just 20W of power – a fifth that of comparable designs. It will drive even the largest tower loudspeakers without exuding much effort, all the while fitting it tight spaces and working in poorly ventilated areas. A Class A input stage comprised of discrete FETs and a semi-toroidal transformer amplifies and buffers the signal with astute precision and transparency. Switchable gain and mute settings plus XLR and RCA inputs complement an overachieving component that also includes a two-year manufacturer's warranty. Music Direct's Money-Back Guarantee does the rest.
