Integrated amplifiers — Cary Audio CAD-300SEI

The CAD-300SEI is a distinctive integrated amplifier from Cary Audio, a well-established American manufacturer known for accomplished tube-informed electronics engineering, built around the celebrated 300B output tube referenced in the model name. The CAD-300SEI brings Cary's considered engineering to a single-ended triode integrated format.

Key specs that matter

Output power is a modest 15W into both 8 and 4 ohms - a classic single-ended triode figure reflecting the inherent power limitations of this celebrated topology. Frequency response spans 20Hz to 23,000Hz within plus-or-minus 3dB. At 203 x 356 x 356mm and 23.1kg, the CAD-300SEI's considerable weight for its modest power output reflects serious internal transformer engineering consistent with quality single-ended triode design.

Sound and use context

Expect the exceptionally rich, harmonically textured character single-ended triode 300B-tube amplification is broadly celebrated for among tube enthusiasts, with the modest 15W output demanding notably efficient loudspeaker partners.

Pairing

The modest 15W output pairs best with notably efficient loudspeakers - typically 90dB sensitivity or higher - to achieve satisfying dynamic headroom, given the inherent power constraints of single-ended triode operation.

Alternatives

Cary's broader tube amplifier catalogue offers alternatives at different power levels for buyers wanting a different balance of features.
