Different price classes - Parasound Halo HINT 6 costs roughly 3.6x what Yamaha A-S801 does. Expect it to lead on paper; the question is whether you will hear the difference through the speakers you own.
| Area | Better | Why |
|---|
| Power | A | Parasound Halo HINT 6 has more power - 160W against 100W into 8 ohms. That is about 2dB, so it plays usefully louder before it runs out and has more in hand on peaks. |
| Room size | depends | We rate Parasound Halo HINT 6 the better fit for a very large room, and Yamaha A-S801 for desk or near-field listening, a small room and a mid-size room. Match the amplifier to the room you actually have, not the one you want. |
| Noise floor | A | Parasound Halo HINT 6 is the quieter design on paper - 103dB against 99dB. Audible mainly with sensitive speakers in a quiet room. |
| Built-in DAC | evenly matched | Both have a DAC on board with much the same capability. |
| Analogue inputs | A | Parasound Halo HINT 6 takes more analogue sources - 8 against 6. |
| Room to grow | evenly matched | The same expansion options on both. |
| Amplifier class | depends | Parasound Halo HINT 6 is Class A/AB and Yamaha A-S801 is Class A/B. Class A/B runs warm and is the long-established mainstream choice. Modern examples of both measure well - judge by the rest of the page. |
| Price | B | Yamaha A-S801 costs less - $900 against $3,199 at list. |
| Watts per dollar | B | Yamaha A-S801 is the cheaper watt - about $9 per watt against $20. A blunt measure, and it says nothing about how either sounds, but it is the honest one for raw output. |

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?
The usual trade-off: Parasound Halo HINT 6 measures better, Yamaha A-S801 costs about 72% less. With most speakers in most rooms that gap is smaller in practice than it looks here. Start with the room. In a large or open-plan room, or with speakers that are hard to drive - low sensitivity, or an impedance that dips - Parasound Halo HINT 6 has the headroom, and headroom is what stops an amplifier hardening up on peaks. At desk distance or in a small room, 100 watts is already more than most people ever use, and the extra 60 watts would be headroom you pay for and never hear - we rate Parasound Halo HINT 6 poorly for near-field use for exactly that reason. Think about the whole system: the roughly $2,299 saved by taking the cheaper one would buy better speakers or a subwoofer, which does more for the sound than the difference between two competent amplifiers.
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.
