The STR Integrated Amplifier is an integrated amplifier with built-in DAC and phono stage from Anthem, a Canadian manufacturer, built with comprehensive connectivity and exceptionally clean measured performance. The STR Integrated Amplifier brings Anthem's considered engineering to a comprehensive all-in-one system solution.
Key specs that matter
One balanced XLR input and four single-ended RCA inputs plus two dedicated phono inputs are provided, alongside a built-in D/A converter. MC phono current-sensing input impedance is 100 ohms, or 47k ohms for MM. Output power is 200W into 8 ohms, doubling cleanly to 400W into 4 ohms - a textbook power doubling indicating a robust, well-regulated power supply. Frequency response spans 10Hz to 80,000Hz within plus-or-minus 3dB. Signal-to-noise ratio reaches 112dB, with total harmonic distortion plus noise at an exceptionally low 0.0008%. At 172 x 432 x 445mm and 18kg, the STR Integrated Amplifier represents a substantial commitment for a comprehensive all-in-one solution.
Sound and use context
Expect exceptionally clean, powerful amplification reflecting the strong 112dB signal-to-noise and sub-0.0008% distortion figures, combined with comprehensive built-in DAC and phono functionality covering digital and vinyl sources directly.
Pairing
The built-in DAC and dual phono inputs cover digital and vinyl sources directly, and the clean power doubling into 4 ohms suits a wide range of loudspeaker impedances.
Alternatives
Anthem's broader amplifier and processor catalogue offers alternatives for buyers wanting a different balance of features within the same considered Canadian engineering philosophy.
