"Indefatigable Powerhouse" Audio Alchemy DPA-1 Power Amplifier Outputs 125Wpc and Delivers Engaging Dynamics, Detail, and Depth: Efficient, Compact Design Features Pure Class-A Input Stage
Designed by Peter Madnick, the highly efficient Audio Alchemy DPA-1 digital power amplifier delivers the kind of outstanding dynamics, detail, dimensionality, and depth that make you feel you're at the musical event. Robustly powerful – 125Wpc into 8 ohms, 200Wpc into 4 ohms – DPA-1 marries the musicality of Class A amps with the power, dynamics, and efficiency of state-of-the-art Class D models. This U.S.A.-made masterwork specializes in rhythmic drive, wide soundstaging, and authoritative bottom-end sound. You'll experience your favorite albums with the kind of definition and articulation every audiophile desires. Full-bodied tones, impactful punch, delicate nuances, and fast transients will go from having been a dream and become a reality. DPA-1 truly offers performance that belies its price and takes no engineering shortcuts.
"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
Just 10.5 inches wide and 16 pounds, the aesthetically clean DPA-1 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 pure Class A input stage comprised of discrete FETs and a semi-toroidal transformer amplifies and buffers the signal with astute transparency precision and transparency. Switchable gain and mute settings, XLR and RCA inputs, and an upgradeable dual-mono power supply option complement an overachieving component that also includes a two-year manufacturer's warranty. Music Direct's Money-Back Guarantee does the rest.
"This range is so exciting, so intrinsically ‘right’ sounding, and so much damn fun you can’t help but like it a lot. And something this right helps legitimize Class D in the minds of skeptical audiophiles who have been told if it isn’t hot and heavy, it isn’t any good. In short, the Audio Alchemy components are all true high-end equipment that just forgot to be heavy and expensive. Very highly recommended!"
—Alan Sircom, Hi-Fi+ (review of Audio Alchemy DDP-1 and DPA-1)
"The DPA-1 is a beautiful small-sized device that distinguishes itself from many other heavy-duty high-end devices while it has a strikingly appealing sound beyond its class, and its massive output power is noteworthy."
