The ANV-50 is an integrated amplifier from Sugden Audio, built with a modest, class A-typical output level. Sugden Audio is a British manufacturer known specifically for class A amplification, which it has pursued consistently for decades rather than moving toward higher-power class AB or class D designs.
Position in line
It belongs to Sugden Audio's integrated amplifier range, which also includes the more elaborate Masterclass IA-4.
Key specs that matter
Five single-ended inputs are provided. Rated output is 50 W into 8 ohms, rising to 100 W into 4 ohms. Input sensitivity is 110 mV. Rated bandwidth is 12 Hz to 45 kHz. Signal-to-noise exceeds 85 dB. At 143 x 430 x 370 mm and 11 kg it is a moderate-weight chassis.
Sound and use context
Class A operation runs continuously at a fixed bias regardless of the music playing, a design choice associated with freedom from crossover distortion.
Pairing
Five single-ended inputs cover a substantial source lineup without needing external switching.
Alternatives
The A21SE, whose name references one of Sugden's best-known historical amplifier designs, is the closest in-house alternative, also built around class A operation.
