One is a streaming all-in-one and the other is an amplifier. Judge them on how many boxes you want and what you already own, not on the spec sheet alone.
| Area | Better | Why |
|---|
| Power | evenly matched | Effectively the same output - 60W against 50W into 8 ohms is under 1dB, which is not an audible difference in loudness. |
| Grip on hard loads | A | Yamaha A-S301 holds up better into a 4-ohm load: its output barely increases to 70W, where the other barely increases. That matters with demanding speakers far more than the 8-ohm figure does. |
| Noise floor | evenly matched | Much the same signal-to-noise ratio (99dB vs 100dB). |
| Built-in DAC | B | Both decode on board. HiFi Rose RS201E goes higher - 384kHz against 192kHz. Very few recordings exist above 192kHz, so treat this as headroom, not as sound quality. |
| Streaming | evenly matched | Only HiFi Rose RS201E has Roon. Neither list is longer in a way that matters - check the one service you actually pay for. |
| Analogue inputs | A | Yamaha A-S301 takes more analogue sources - 6 against 1. |
| Phono stage | depends | Yamaha A-S301 has a built-in phono stage (MM) and HiFi Rose RS201E does not. Decisive if you own a turntable, completely irrelevant if you do not - and an outboard phono stage is easy to add later either way. |
| Room to grow | A | Only Yamaha A-S301 offers A/B speaker terminals - which decides whether you can add a subwoofer or a power amplifier later without replacing the box. |
| Amplifier class | depends | Yamaha A-S301 is Class A/B and HiFi Rose RS201E is Class D. Class A/B runs warm and is the long-established mainstream choice; Class D runs cool and draws almost nothing at idle. Modern examples of both measure well - judge by the rest of the page. |
| Shelf space | depends | HiFi Rose RS201E takes up about 60% less shelf area (672cm² against 1701cm²), and it is 151mm shallower, which is the measurement that decides whether a rack door shuts. |
| Price | A | Yamaha A-S301 costs less - $350 against $2,195 at list. |
| Watts per dollar | A | Yamaha A-S301 is the cheaper watt - about $6 per watt against $44. A blunt measure, and it says nothing about how either sounds, but it is the honest one for raw output. |
A Yamaha A-S301 B HiFi Rose RS201E
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both amplifiers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
Yamaha A-S301 is the easier recommendation: it leads on most of the measured areas and costs less. Take HiFi Rose RS201E if one of the "depends" rows above describes your system. If your speakers are a difficult load - 4 ohms nominal, big woofers, or a sensitivity in the low 80s - Yamaha A-S301 is the safer partner, because how an amplifier behaves when the impedance drops matters more than its 8-ohm rating. If you play records, Yamaha A-S301 saves you buying a phono stage; if you do not, ignore that row entirely.
What a spec sheet cannot show: how either sounds with your speakers, how the controls feel day to day, and what the app is like to live with - which is where most all-in-one amplifiers are actually won or lost. Power figures are the manufacturers' own and are not measured to a common standard, so treat small differences as noise. If you can hear both, that will tell you more than any row above.
