Power amplifiers stereo — Chord SPM 1050 MKII

The SPM 1050 MKII is a stereo power amplifier from Chord, built with a substantial output and wide rated bandwidth. This model represents a considerably more ambitious power amplifier within Chord's catalogue than the compact Anni, offering genuine output for a serious two-channel system.

Key specs that matter

Input impedance is 100,000 ohms for both balanced and single-ended connections. Rated output is 200 W into 8 ohms. Rated bandwidth is an exceptionally wide 0.2 Hz to 46 000 Hz. Signal-to-noise is 82 dB. At 133 x 420 x 355 mm and 10 kg it is a compact, light chassis for its considerable 200 W output, consistent with Chord's characteristic engineering approach favouring compact, efficient designs over conventional heavy linear amplifiers.

Sound and use context

Expect a controlled, wide-bandwidth presentation from a compact chassis relative to its considerable output - Chord's characteristic engineering ambition applied to power amplification, offering substantial capability without the bulk a conventional design of similar output would typically carry.

Pairing

The 100,000 ohm input impedance works with any modern preamplifier without gain-matching concerns, so integration should present no particular challenge regardless of the preamplifier chosen.

Alternatives

Chord's compact Anni sits well below this model for a nearfield or desktop application with modest power needs, worth considering instead if this model's substantial 200 W output exceeds what a specific room and loudspeaker pairing requires. Chord extensive dealer network makes arranging a direct comparison against the compact Anni practical, helping clarify exactly how much additional output and scale this more substantial model buys for a specific room and loudspeaker pairing. A rigid, well-supported equipment shelf remains worthwhile even for a chassis this compact given its considerable output, and standard connectivity here works with any preamplifier accepting a conventional source connection. Overall this remains a capable power amplifier choice within Chord distinctive engineering catalogue. A dealer visit remains the simplest way to compare current pricing across Chord amplifier lineup. Adequate ventilation space around the chassis also helps this amplifier run reliably over long sessions. A dealer demonstration remains worthwhile before committing to any specific purchase decision.
