AURUM A8

Top-of-the-line amplifier
AURUM 8 is our new high-end, complete, all-rounder, champion amplifier –handmade in Germany – based on double mono architecture with separated current supplies, signal processing as well as amplification. We outbid the whole spectrum of technical and scientific knowledge of circuit technology with our integrated high-end amplifier so you can enjoy an extraordinary level of listening pleasure. The ability for us to create a powerful reference amplifier that delivers such fabulous dynamics and both a rangy and finely detailed sound reproduction is paramount to our beliefs and objectives.

Level of protection

•Class-AB output stage for low distortion sound and great sonority.
• Undisturbed operation at the highest level through individually decoupled sections.
• Separate power supplies for standby power and digital and analogue modules.
• The wideband filter clears external balanced disturbances from the power grid and unbalanced disturbances from housing and „ground wire“.

Input switching:

• High quality, encapsulated signal relay and hard-gilded contacts for optimum signal transmission.
• Almost wear-free relay for an exceptional long lifetime.

Input Level:

• Particularly low distortion and low-noise due to BI-FET operational amplifiers for the widest frequency range and clear increased dynamics in music reproduction.
• Low-noise operational amplifiers from Texas Instruments for a sensitive input stage.

Signal Forwarding:

• Efficient signal transmission with minimized distortion.
• Optimized module architecture for short signal paths.
• High-quality polypropylene film capacitors made in Germany.
• Extreme interference suppression and loss-free signal forwarding through SMD technology (an innovative technology for the production of assemblies).

Real double-mono-construction:

• Separate power supply for each channel, individual signal processing and individual signal amplification for more strength, dynamics and performance reserves.
• Two separately operated, stray power supplies, a transformer and a rectifier for a finely-resolving and stable sound.
• balanced inputs (XLR) for optimal signal transmission. This professional type of connection allows signal transmission with a ground wire exclusively used for shielding and on which itself no signal flow takes place.

Pre-amplifier and full-amplifier:

• Professional, precise and logarithmic working volume adjustment as in the studio with real 1 dB steps.
• Exactly synchronized volume control of the audio channels.

AURUM A8 & C8

Full amplifier Aurum A8 and CD player Aurum C8

Wishful thinking

The new combination of full amplifier Aurum A8 and CD player C8 provides independent of the musical genre and the connected Loudspeakers long, relaxed and at the same time stimulating listening sessions. It is the consistent development of the Aurum product range. The high-quality processing, the certainty that these timeless devices result from manual work in Germany (this applies even to the circuit boards!) and the consistent sound - tuned electronics are on the plus side of the combination. The amplifier is powerful, musical and without preference for a musical direction or certain frequency ranges - it is balanced and playful. I almost liked the CD player even more – next to its excellent timing, especially due to the open and distortion-free recording analog Class-A output stage. A real insider tip in this price class.

AURUM A8 und C8

Fazit:

Mit dem CD-Player CS und dem Voll­verstärker AS erweitert Quadral seine Aurum Serie um zwei tolle Produkte, die in Kombination durch ihren gut­mütigen aber klaren Sound zu begeis­tern wissen. Das präzise Playback des CS ergänzt sich hervorragend mit der bassstarken Wiedergabe des AS. 

 

Testurteil:

AURUM A8: sehr gut
AURUM C8: sehr gut
