PH-1

PH-1 tube + MOSFET High grade headphone (pre-amp) amplifier My music, my space. Listening to music with headphones is the easiest way to achieve the effect of high-fidelity, as headphone is close to ear, the acoustic factors will not be influenced by environment, no reflection,no interference, no superposition,no standing waves and other undesirable phenomenas. Sound run a very short path directly into the eardrum,reduce all transmission distortion,make you enjoy the most wonderful life-like music. This the reason why professional sound engineers prefer to use headphones to listen to music when they are working.In addition, listening to music with headphones are not influenced by external noise, also will not affect the family's work and learning, it is totally self-space joy. Introduction: 1, use tube and FET hybrid amplification circuit,input and voltage amplification use tubes,what follow is current drive which is constituted also by tubes,has the characteristics of stro
