Интегральные усилители — HiFi Rose RA280

The RA280 is an integrated amplifier with built-in phono stage from HiFi Rose, the Korean electronics brand that has rapidly built a considerable reputation for sonics, functionality and value. The RA280 combines analogue amplification, digital conversion and phono playback into one comprehensive 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 - a substantial, load-tolerant figure suggesting a robust power supply and output stage. 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 - both strong figures. Total harmonic distortion plus noise is an exceptionally low 0.007%, with damping factor exceeding 250, indicating excellent control over a connected loudspeaker's driver movement. At 430 x 355 x 103mm and 9.5kg, the RA280 keeps a compact footprint for its considerable feature set.

Sound and use context

Expect clean, dynamic and well-controlled sound reflecting the amplifier's exceptionally low distortion and high damping factor - the identical 250W output into both 8 and 4 ohm loads suggests a design engineered for genuine loudspeaker-load tolerance rather than a supply that sags under demanding impedance.

Pairing

The built-in MM/MC phono stage covers a turntable directly without a separate outboard phono preamplifier, and the balanced input alongside three single-ended inputs comfortably accommodates a source-rich system.

Alternatives

HiFi Rose's broader amplifier and all-in-one catalogue offers alternatives for buyers wanting a different balance of built-in streaming, display or phono functionality, worth comparing directly if the RA280's specific feature set doesn't precisely match a particular system's requirements. The compact chassis size relative to its considerable output and feature set reflects HiFi Rose's broader design philosophy of packing genuine performance into space-efficient enclosures.
