Externally, the new Powernode looks like its predecessor: a black or white plastic box with rounded corners and a control panel on top. The panel is more advanced than before, as there is now a touch field for controlling volume, as well as five presets that can be programmed with internet radio stations or playlists.
It would have been the icing on the cake if the touch panel included a display so you could see what was behind the buttons.
Otherwise, most operation is via the Bluesound mobile app, and usability is on par with Sonos. Bluesound also has several options for high-resolution audio, if you’re interested in that. In addition, the Powernode can be controlled with Google Assistant and Amazon Alexa.
You can buy a separate remote, but if you connect the TV via the HDMI jack, you can use the TV’s remote to adjust the sound up and down.
On the back, the Bluesound Powernode has a USB port and two combined analogue/digital inputs. But frankly, you get a long way with the streaming functions plus the TV via HDMI.
If you want surround sound, the amp can be part of a multi-channel system (up to 5.1 channels) along with, say, a Bluesound soundbar or separate speakers. If you have an older Powernode, it can also be set up to drive the rear speakers.
The sound of Bluesound Powernode
It’s easy to underestimate the Bluesound Powernode. The little lunchbox of an amplifier weighs only 1.8 kg and looks like a toy. But with a couple of decent speakers hooked up, it gets serious.
The balance of the soundstage is distinctly uncoloured, but the sound is anything but flat and dull. The bass is stable and energetic, and there’s good midrange punch on the violins in Mozart’s Piano Concerto No. 21. The resolution upwards is good too, this is really good!
Pop music has good pressure – just listen to the bass rhythms on Ariana Grande’s “Break Up With Your Girlfriend”. It’s fierce, it’s cool, it’s delicious.
Powernode reproduces the space in which the recording takes place well, whether it’s a live recording or audio put together in a studio. It’s very transparent and you can place instruments and voices on stage.
When pushed to the limit, the amp loses the ability to separate out the small details, but then it’s also miles ahead of the others in the test in terms of sound pressure. And when it does get strained, it does so in a civilised way without sounding ugly.
The Bluesound Powernode (N330) is even better than its predecessor, and although the price has gone up since we last tested it, it stands out so strongly from the field that this is quickly forgiven.
It’s clearly worth the extra price compared to the Sonos Amp and its peers, and is the amp in the price range that yours truly would choose if the format were small. Perhaps in any case, because it doesn’t stand up to bigger amps either.
When we tested it alone last year, Powernode gave it five stars. Now, after pitting it against the rest of the field, it’s clear that it should get full marks. Best in test!
