“Little Silver Fox” - Headphone Amplifier

The Cen.Grand 9i-806, known as the “Little Silver Fox” by the audio press and fans, is a high-performance headphone amplifier that is a simplified version of the manufacturer’s flagship, the legendary 9i-906 "Silver Fox" model. While some components and solutions have been simplified for a more favorable price, the 9i-806 has preserved all the essential sonic virtues that made its predecessor famous and respected worldwide.

Innovative circuit architecture and output modes

Innovative circuit design and output modes

The 9i-806’s circuit topology evokes the complexity of high-performance power amplifiers. The amplifier’s output features 4 pairs of high-power British-made FET transistors, delivering exceptional current capability. This allows the device to precisely drive even ultra-low sensitivity headphones while preserving the music’s natural tone and detail.

Output modes:

Balanced
(BTL)

higher output power

Active G
(virtual ground mode)

high stability

Parallel
(parallel mode)

ideal for low impedance matching

Normal
(symmetrical)

Multiple output modes allow the user to optimize drive for headphone type and listening preferences.

Differences compared to the 9i-906 "Silver Fox"

While the 9i-806 “Little Silver Fox” is the little brother of the 9i-906 “Silver Fox” and follows the same neutral, high-resolution sound, certain key points have been simplified for a more accessible price.

• - In terms of volume control, the 9i-806 uses a classic potentiometer, while the 906 utilizes a premium MUSES72320 IC and MUSE02 op amp - providing more precise channel balance and lower noise.
• - The power supply is more modest as well: the 806 uses a smaller transformer, but still delivers plenty of power. The 906 is more robust and even more stable in this aspect.
• - Component quality also differs - the 9i-806 is built with value-optimized parts, while the 906 offers uncompromising audiophile solutions in every detail.

The 9i-806 is thus a highly capable, affordable alternative with the “Silver Fox” character - minor compromises, but impressive performance.
