The nickname of 9i-906 headphone amplifier is “silver fox”. Purpose is to drive “monster” headphones. Its circuit architecture originates from a large power amplifier. When many redesigns for electrical characteristics and adjustments of sound style were completed, “silver fox” became a wonderful headphone Amp. High analytical, high density and neutral without tendency, especially power driving fprce, 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 chaeracteristics of headphone more than normal headphone amp.

9i-906 “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/20W. 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.
