The new quadral AURUM active streaming loudspeaker AURUM GAMMA – Wi-Fi, USB-A, UPnP/NAS, S/PDIF (optical)
ELECTRONICS
Concentrated power and sophisticated control are the central features of the new AURUM active electronics. Both models are powered by high-performance Class D amplifiers for the subwoofer and midwoofer range. Musical analogue amplifiers are used for the tweeters.
The AURUM GAMMA achieves an impressive 350W@1%THD. The modules are controlled using a high-power digital signal processor (DSP). The DSP sets extremely precise requirements for each speaker chassis. To minimise the room influence, a full version of the multi-award-winning DIRAC® calibration system is included in the package. The performance is polished by analogue symmetrical/unsymmetrical inputs and an optical S/PDIF digital input.
ACOUSTIC COMPOSITION
Maximum performance from the smallest box – the new AURUM active model in short. To produce such great output from such a compact device requires a sophisticated overall design.
The basses play in a closed chamber: this concept is ideal for the cleanest impulses and a melodic, musical bass. It saves space but it needs a long-throw, low-distortion subwoofer and lots of power – no problem for the new AURUM active model. The full active loudspeaker with 350W and 700W guarantees unlimited dynamic.
To ensure the resulting heat for this enormous performance doesn‘t become a problem, the electronics are situated in a separate chamber with a flue-effect ensuring effective heat dissipation. This chamber alone requires as much space as a small tower speaker.
To create a slim front with good all-round emission, the woofers are placed on the side – a particular challenge for the midrange. These are isolated from each other and require a huge amount of power but still have very low distortion. The 15 cm and 18 cm mid range of the AURUM passive series pass this test with flying colours.
STREAMING
The best feature of the AURUM active model is undoubtedly its option to stream music from different sources. The simplest way: insert a USB stick with music files, select it in the app and enjoy listening immediately.
You can also connect your home network through the app in just a few clicks to play the entire music collection saved on a favourite network drive. If you like listening to the radio now and again, the AURUM active loudspeaker can also access hundreds of radio stations or podcasts through Airable®. To cover the many streaming services, we have also integrated Tidal® initially due to its high-resolution data format, with vastly superior sound to standard compression.

TEST: QUADRAL AURUM GAMMA FLOORSTANDING LOUDSPEAKER – ACTIVE VOLCANO
“You can tell from the Quadral Aurum Gamma that it contains a lot of experience from the Aurum collection. From the construction of the speaker to its assembly, everything speaks the language of Quadral’s demanding development work. Now, however, we are keeping up with the times, which is why the Aurum Gamma is an established universal genius, which can also be adapted to any spatial situation with Dirac”.
Overall result: 94%.

Conclusion
“Acoustically, hardly any more is possible – and it is questionable who in practice actually still actively needs the two larger alpha for a complete price of 16,000 EUR. Even the “small” gamma speakers are far removed from most of the other active loudspeakers known to us in all disciplines: Extremely stirring, extremely precise, extraordinarily plastic and equipped with an outstanding level stability, they set standards here that also put the high purchase price in a different light.
The room correction Dirac Live works extraordinarily precise. In addition, the user can create up to four different profiles, e.g. for different music styles. Although one has to be a little experienced for the Dirac calibration, with a little good will and a little patience, this should succeed in practice.
Visually, the Gamma comes along chic and straightforward. With an excellent surface quality, a very high quality unibody cabinet and cleanly worked cabinet corners, exactly the demands that buyers of expensive, noble loudspeakers have are met with ease.
Of course there are also points of criticism. These include the missing Apple AirPlay 2 integration and the few streaming music services that are currently available. Spotify Connect and the equally popular quboz would be welcome. The fact that there is no USAB DAC must also be mentioned as a disadvantage.
The conclusion is clear: At the moment it might be difficult to find a similarly captivating and at the same time extremely sovereign and cultivated sounding active box on the market. The Quadral Aurum Gamma is therefore a real highlight from Hannover”.
