Integrated amplifiers — HiFi Rose RA280

The RA280 is an integrated amplifier with built-in phono stage from HiFi Rose, a Korean electronics brand. The RA280 combines analogue amplification, digital conversion and phono playback in one chassis, aimed at buyers wanting a complete system hub without assembling separate components.

Key specs that matter

Connectivity includes one balanced analogue input, three single-ended analogue inputs plus a dedicated MM/MC current-sensing phono input, with input sensitivity of 600mV on line inputs and 5mV on phono, and input impedance held at 47k ohms across both balanced and single-ended connections including the phono stage. A built-in D/A converter handles digital sources directly. Output power is 250W into both 8 and 4 ohm loads. Frequency response spans 10Hz to 85,000Hz within plus-or-minus 3dB, with signal-to-noise ratio at 109dB on line inputs and 85dB on phono. Total harmonic distortion plus noise is 0.007%, with damping factor exceeding 250. At 430 x 355 x 103mm and 9.5kg, the RA280 keeps a compact footprint for its feature set.

Pairing

The built-in phono stage covers a turntable directly without a separate outboard phono preamplifier, and the input count accommodates a source-rich system.

Alternatives

HiFi Rose's broader amplifier and all-in-one catalogue offers alternatives with a different balance of built-in streaming, display or phono functionality.
