Cen.Grand 9i-806 “Little Silver Fox”
The DNA of the Silver Fox, in a new form
“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.
Sound and performance - without compromise
The sound character of the 9i-806 is best described as neutral, high-resolution, and possessing dense texture. This amplifier superbly captures musical dynamics while remaining detailed and controlled across the entire frequency range. The 15-watt (BTL, 30Ω) output is outstanding even in audiophile circles and is more than enough to effortlessly drive even the highest demand planar magnetic headphones.
The aim in development was to distill the Silver Fox’s spirit and technology into a more cost-effective, yet uncompromising device. The “Little Silver Fox” is not just an entry point to the high-end segment, but a real alternative even for experienced audiophiles seeking to exploit the full potential of their headphones.
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.
Universal matching - compatible with all headphones
The 9i-806 is one of the most versatile headphone amplifiers on the market: with three low-impedance and one high-impedance mode, it easily adapts to virtually any headphones - be they dynamic, planar magnetic, low or high sensitivity.
The four different headphone impedance modes:
- - High Resistance - recommended in most cases
- - Low Resistance 1-3 - especially useful for ultra-sensitive earphones or IEMs where minimizing noise is crucial
Inputs and outputs - audiophile flexibility
The 9i-806 input and output possibilities cover every need:
Inputs:
2 balanced (XLR)
2 unbalanced (RCA)
The unbalanced inputs are automatically converted to balanced by the internal circuitry, meaning that even with RCA signals you benefit from maximum output drive.
Tip: For best sound quality, use the balanced (XLR) inputs.
Outputs:
4-pin XLR
(balanced)
4.4mm Pentaconn
(balanced)
2 x 3-pin XLR
(balanced)
2 x 6.35 mm jack
(stereo, parallel)
User-friendly interface
The device features minimal, dedicated audiophile controls to keep your focus on the listening experience. Only the most essential controls are present:
- - Power button
- - Input selector
- - Output mode selector
- - Impedance mode selector (long press to toggle)
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.
