Product details:During the actual assembly process, some components may differ from those shown in the picture due to the need for sound calibration. Do not purchase if you mind.
1.The preamp and headphone amplifier are combined into one and work simultaneously, with completely independent volume control.
2.Four sets of audio inputs, independent preamp and headphone output, each independent.
3.The preamp section is completely independent of the headphone amplifier section in terms of power supply and circuit.
4.A reasonable layout results in an extremely excellent signal-to-noise ratio, with a preamp of -113dB and a headphone amplifier of -114dB.
5.Customized 50W high-quality Toroidal transformer is encapsulated in a 1.2mm thick iron cover, minimizing vibration and electromagnetic interference.
6.All aluminum alloy CNC machining case, showcasing high-end features.
7.High precision surface mount components are widely used because their parasitic inductance is almost zero, and the piezoelectric effect is too small to be measured, which does not introduce nonlinear distortion.
8.Both preamp and headphone amplifier inputs have been buffered with vacuum tubes, effectively isolating digital odors.
