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 - 70W against 80W into 8 ohms is under 1dB, which is not an audible difference in loudness. |
| Noise floor | A | Audiolab 7000A is the quieter design on paper - 110dB against 100dB. Audible mainly with sensitive speakers in a quiet room. |
| Built-in DAC | B | Both decode on board. Bluesound POWERNODE goes higher - 384kHz against 192kHz. Very few recordings exist above 192kHz, so treat this as headroom, not as sound quality. |
| Streaming | B | Only Bluesound POWERNODE has AirPlay 2, Roon and BluOS. |
| Analogue inputs | A | Audiolab 7000A takes more analogue sources - 3 against 2. |
| Phono stage | depends | Audiolab 7000A has a built-in phono stage (MM) and Bluesound POWERNODE 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 Audiolab 7000A offers a pre-out/main-in loop - which decides whether you can add a subwoofer or a power amplifier later without replacing the box. |
| Amplifier class | depends | Audiolab 7000A is Class A/B and Bluesound POWERNODE 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 | Bluesound POWERNODE takes up about 72% less shelf area (420cm² against 1510cm²), and it is 150mm shallower, which is the measurement that decides whether a rack door shuts. |
| Price | B | Bluesound POWERNODE costs less - $949 against $999 at list. |
A Audiolab 7000A B Bluesound POWERNODE
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: Audiolab 7000A measures better, Bluesound POWERNODE costs about 5% less. With most speakers in most rooms that gap is smaller in practice than it looks here. If you play records, Audiolab 7000A 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.
