Integrated amplifiers — Copland CTA407

The CTA407 is an integrated amplifier with built-in DAC and phono stage from Copland, sharing the CSA100's exceptionally wide bandwidth within a more modest power specification. The CTA407 brings Copland's considered engineering to a complete integrated chassis.

Key specs that matter

Four single-ended inputs plus a dedicated phono input are provided. Input sensitivity is 200mV, with input impedance at 50,000 ohms single-ended. The phono stage uses a sophisticated current-sensing design at 47,000 ohms, matching the CSA100. Output power is 50W into both 8 and 4 ohms - a modest, characterful figure suggesting tube-informed design. Frequency response spans an exceptionally wide 10Hz to 150,000Hz within plus-or-minus 3dB, matching the CSA100. Signal-to-noise ratio is 100dB - higher than the CSA100's 90dB, with total harmonic distortion plus noise at 0.5%. At 435 x 215 x 420mm and 20kg, the CTA407 represents a more substantial commitment than the CSA100 despite the more modest power output.

Sound and use context

Expect the warm, richly textured character tube-informed amplification is broadly celebrated for, with the modest 50W output best suited to notably efficient loudspeakers, combined with the built-in phono stage covering vinyl directly.

Pairing

The modest 50W output pairs best with notably efficient loudspeakers to achieve satisfying dynamic headroom.

Alternatives

Copland's own CSA100 offers a considerably more powerful alternative within the same broader integrated amplifier catalogue.
