2). K701/K702/Q701
3). DT880/T70/T90
4). SR225/SR325/RS1e
Feature
1. Use 2pcs 6E2 tube as signal level indicator, 2pcs 6N3 tube for left and right channels, each served with SRPP voltage amplification, and then adopt a 6N5P tube for cathode output of left and right channel. Its noise level has been able to achieve practical requirements.
2. USB decoder: it is a tube amp with USB DAC function, U202 USB DAC portion is made of USB receiver and separate decoder chips, USB decoder chip used as CM108.Through repeated the tests, not only does U202 supports USB2.0 high speed transmission, but the thickness of sound and stability is much better than high cost of PCM2706 chips for USB1.1 profile, which is the main reason we chose it.
3.DAC decoding portion use a TDA1305T chip of famous Ph ilips which is its excellent sound quality and some foreign famous brands of CD, amplifier manufacturers widely used .

Connection method
1. Computer == "3.5 to RCA cable ==" U202 headphone amplifier == " headphone amp
2. CD player == "RCA to RCA cable ==" U202 headphone amplifier == " headphone amp
3. I PAD == "3.5 to RCA cable ==" U202 headphone amplifier == " headphone amp
4. Computer USB ( the unit has a decoder ) == "RCA to RCA cable ==" U202 headphone amplifier == " headphone amp
Note:
1. Heat start-up of tube amplifier is stable after power on for 15 seconds, it can start working properly aloud.
2. The unit is a pure Class A tube output and power consumption is about 40W, so heat is great, please pay attention to ventilation when using, and prevent be scalded by the tube overheating. It is normal that the unit is high temperature for some time is use, do not worry about it, it will be self- recovery protection when temperature is above 95 degree Celsius.
3. When it is used as a preamp, please do not put the volume knob for this unit as entire audio system volume control knob, to prevent the unit’s inherent background noise be amplified by power stage when it is in maximum gain, and avoid that the background noise of pre-amplifier amplified is bigger than useful signal in a small volume), it is strongly recommended that volume knob of power stage amp 's as the size of the volume control of the entire sound system.
Applications
If the U202 match the 2x 100W HIFI transistor amplifier, they are a heaven-made match, they will provide you high performance and excellent exprierences.
