Overview
The DSi200 is our first product in the “Definition Series” showcasing a new technology that offers extremely high performance and value. Based on an advanced new design created entirely from the ground up by our engineering team, the DSi200 is built in-house by our own craftspeople.
The Definition Series of amplifiers represents an unusual type of “solid-state hybrid” design in which a massive, highly regulated, linear analog power supply is combined with a truly “green” discrete analog switching-MOSFET output stage for highly efficient power conversion and low power consumption. The analog power supply and all-discrete MOSFET output stage are pure Audio Research expressions and do not rely on prepackaged modules or other “OEM” solutions common to amplifiers from other manufacturers.
Many music lovers have not favored efficient switching amplifier designs because their sonics have been disappointing on an absolute basis. Class-D amplifiers could sound good but they did not possess the level of refinement found in the best discrete analog class-AB designs. The DSi200 is not a typical switching amplifier with a switching power supply, and it doesn’t sound like one – it will surprise you with its musical purity, low noise floor, uncanny resolution and startling dynamics.
The DSi200 delivers 200 WPC continuously into an 8-ohm load, 400+ WPC dynamically into 8 ohms, and 800+ dynamically into 4 ohms. In the real world, this allows the DSi200 to control large, power-hungry speakers with remarkable ease. All this is generated with almost no heat from a moderately sized enclosure – the DSi200 has earned an Energy Star rating.
The DSi200 is a fully balanced design offering two sets of balanced inputs and three sets of single-ended inputs. One set of single-ended inputs can be used as a normal line-level input or it can be converted into a home-theater passthrough. This is important because the preamplifier section of the DSi200 is passive, so its preamplifier and amplifier sections cannot be separated. The DSi200’s appearance is a modern evolutionary step for Audio Research that is both contemporary and familiar. The heavy front panel features Volume and Input selectors flanking a vacuum-flourescent display. The brightness of the display can be adjusted to one of six levels, plus off-nine small pixels remain lit as a discreet reminder that the unit is powered on.
Control functions under the display are actuated via four small, round aluminum buttons; functions include Power, Mono, Invert, and Mute. The supplied remote control accesses these functions, plus a Left-Right balance control, and Display Up and Display Down controls. Silver handles are standard, but the most striking visual update may be the silver chassis that matches the handles and knobs. The DSi200 is also available with a black front panel, handles and knobs, but the chassis and wraparound cover will only be available in silver.
