9i-806 "Little Silver Fox" headphone Amp is simplified version of 9i-906 :Silver Fosx". Most Advantages of 9i-906 have been preserved but the price is lower than it. Very good value for money.

9i-806 "silver fox" headphone amplifier is "Little silver fox". Purpose is the same as 9i-906 "Silver Fox" , both for driving“monster” headphones. Its circuit architecture originates from a large power amplifier. When many redesigns for electrical characteristics and adjustments of sound style were completed, "Little Silver Fox" became a wonderful headphone Amp like "Silver Fox" . High analytical, high density and neutral without tendency, especially power driving force, make it leader in similar products . Whether high sensitivity or low ,high resistance or low , dynamic earphone or flat panel headset, "silver fox" can adapts to them by it's super driving ability and quality. It can show the characteristics of headphone more than normal headphone amp.

The difference between 9i-806 and 9i-906:

  • 9i-806 uses potentiometer for volume contrl and 9i-906 uses Volume IC Muse72320+ OP Muse02
  • 9i-806 use a smaller transformer than 9i-906.
  • 9i-806 use some cheaper components than 9i-906.

9i-806 "Little Silver Fox" is a headphone power amplifier with high performance, strong power supply and high current output. It's circuit design is complex and perfect , 4 pairs of high-power British FET are used in output part , the output power is 30Ω/15W. Ultra low sensitivity headphones can also be driven with excellent audio performance.

It has four output modes: Normal, Balanced(BTL), Virtual Ground(Active G) and Parallel, as well as three low resistance modes and one high resistance mode. A variety of headphones can be matched.

It has two balanced and two unbalanced inputs . Even if you input an unbalanced signal, the internal circuit will convert it into balanced signal . Therefore, even if you input an unbalanced signal you will also get the maximum output power.

Operating instructions:

"Silver fox" is a pure headphone Amp and the operation is very simple. There are only several function keys: power switch, input selection, output mode selection , high/low resistance selection.

  • Long press the out key to switch between high and low resistance modes.
  • There are four kinds of headphone impedance options for choice : high resistance, low resistance 1, 2 , 3.
  • You can selected any mode according to whether you hear noise .
  • High resistance mode is recommended in most cases.

BTL Output Mode

Recommended for High Impedance Headphones.

Active G Mode

Suitable for listening to Human Voice.
