The Cobra is an integrated amplifier from Audio Note, built with a modest output power typical of the brand's tube-informed philosophy. The Cobra brings Audio Note's considered engineering to an accessible integrated chassis.

Key specs that matter

Three single-ended inputs are provided. Input sensitivity is 300mV, with input impedance at a substantial 100,000 ohms. Output power is a modest 28W into 8 ohms. At 340 x 180 x 450mm and 13.6kg, the Cobra maintains a manageable integrated amplifier chassis reflecting Audio Note's considered, minimalist British engineering philosophy.

Sound and use context

Expect the warm, musically engaging character Audio Note's broader minimalist catalogue is celebrated for, with the modest 28W output demanding notably efficient loudspeaker partners for satisfying dynamic headroom.

Pairing

The modest 28W output pairs best with notably efficient loudspeakers for satisfying dynamic headroom.

Alternatives

Audio Note's own I Zero offers a more compact, even lower-power alternative within the same broader catalogue.
