The RA280 is an integrated amplifier by HiFi Rose that delivers 250 watts x 2 channels into 8 ohms and 250 watts x 2 channels into 4 ohms. It was released in February 2024. It is a 2-channel design using a Class AD output stage. A minimum impedance of 4 ohms makes it compatible with a wide range of loudspeakers. It also has a phono input, so a turntable can connect straight to it. The HiFi Rose RA280 has an MSRP of $3,395.
There are 4 HiFi Rose amplifiers in our database. Below you can see the main specs of these amps.
HiFi Rose Integrated Amplifier Series
Performance Specs
One of the most important factors when deciding on an integrated amplifier is its power ratings and compatibility with your speaker's impedance requirements. The HiFi Rose RA280 is rated at 250 watts RMS into 8-ohms. HiFi Rose provides this wattage at a THD (Total Harmonic Distortion) of 0.007% which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 250 watts into 8-ohms (20 Hz-20 kHz) at 0.007%
- 250 watts into 4-ohms
- 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)
- 109dB Signal to Noise Ratio

Need more power?
HiFi Rose RA280 is rated at 250 watts into 8 ohms, which puts it in our Over 180 watts band. That is the top band we cover, so there is no step up from here - if it is not enough, the answer is more sensitive speakers or a smaller room, not more watts.
When pairing the HiFi Rose RA280 with a passive Bookshelf (Stand mount) or Passive Floor Standing (Tower) speaker, you have to check if their Max Power Range is below the max wattage of the amp for the given impedance levels.
Operating your amp outside of this max range may damage the speakers.
Inputs and Outputs
Besides the performance specs of the HiFi Rose RA280, the next important feature set that you have to evaluate is the input and output selections that it offers.

HiFi Rose RA280 Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓250 watts per channel into 8 ohms is more than most rooms and most speakers will ever ask for.
- ✓Signal-to-noise ratio of 109dB, so the amplifier itself should be inaudible between tracks.
- ✓Distortion is specified at 0.007%, an order of magnitude below what is generally held to be audible.
- ✓Phono stage built in, so a turntable needs no separate preamplifier.
- ✓Dedicated subwoofer output (1).
- ✓Detachable mains lead (IEC 3-prong).
- ✗Output rises only from 250 to 250 watts when the load halves to 4 ohms, so it is happier with an easy 8 ohm speaker than a demanding one.
- ✗Analogue inputs only - a TV, computer or CD transport needs an external DAC.
- ✗No Bluetooth and no network streaming - everything arrives over a cable.
- ✗Parts warranty is only 1 year.
