The new quadral AURUM active streaming loudspeaker AURUM ALPHA - 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.

Conclusion:
"You can tell the aurum gamma that there is a lot of experience from the aurum collection here. From the construction of the speakers to its assembly, everything speaks the language of quadrals demanding development work. Now, however, the time has come why the aurum gamma is a universal universal genius, which can also be adapted to any spatial situation by dirac."

AURUM GAMMA

LowBeats tested AURUM GAMMA and we are happy about the "SURPRISING" verdict.

Conclusion:

"Quadral Aurum Gamma: a smooth One

Concepts such as the Quadral Aurum Gamma are now available in all price and requirement classes. And not a few HiFi fans are of the opinion that with such a powerful equalizer as a DIRAC or similar programs, any loudspeaker can be brought to an audiophile level. This is a mistake. Even DIRAC does not turn bad loudspeakers into high-end speakers. But if the base is really good, you can always hear it through. And - you guessed it - the basis of the Gamma is excellent.

In addition there is the grace of the late birth. Quadral didn't even have to make many of the mistakes that the pioneers of this type of loudspeaker made. Today's electronic platforms function smoothly and the Aurum App ran completely stutter-free during the weeks of testing. In addition to all the smart technology, the Gamma is a large loudspeaker with great sound capability and - thanks to DIRC and DSP - also one that can be made to sound comparatively well even in difficult room acoustics. Among the loudspeakers of this "I can do anything" type tested so far by LowBeats, the Gamma is unquestionably the best. I enjoyed listening to music with all of them. But only with the Gamma have I rediscovered many well-known pieces. Not bad for a debut album.

If I compare a current Quadral Vulkan 9 with the equally equipped Gamma, I get a clear plus in possibilities and sound with the Gamma for just 2,000 Euro surcharge. It doesn't take any great visionary abilities to determine that this kind of music listening - without additional system components - certainly belongs to, if not THE future".
