Feature:
The CR5687 pre-amplifier uses tube rectification and traditional multi-stage capacitor inductance filtering, which retains the design style of the year to the maximum and pursues the old taste. This is a commemorative model in the Raphael amplifier series, which is only customized for fans who like nostalgia or industrial sense.
This CR5687 shape adopts military green with brass knobs and brass signs, which is both retro and military. The front panel of the chassis adopts a sloped design, which makes the viewing angle more direct and the operation more intuitive; the left-to-right functions of the four knobs on the front panel are: front-stage and amp function conversion, phase switching, volume adjustment, and sound source input selection.
The selection and phase conversion of multiple sets of input and output make the user more selective and practical. At the same time, there is a set of 600Ω four-core Canon earphone jack behind the machine, which is convenient for customers to use;
It is important to point out that when the output standard impedance is 600Ω, the power reaches 1700MW, which is close to the power tube. The power can easily drive any post-stage and most headphones, and the sound is full, the bile taste is rich, and the dynamic is strong.
