Yaqin VK-2100 is a high-class hybrid stereo amplifier. It offers rich in details sound with an extremely powerful bass. The sound is transparent, seasoned with sweetness and flavors. The design uses many high-quality components, such as MKP capacitors, Toshiba transistors and a dedicated ALPS potentiometer.
The amplifier uses separate power transformers, a choke. High-capacity capacitors were used in network ripple filtering systems.
The amplifier's front panel has an input selector, potentiometer knob and 1 pair of RCA line inputs with variable sensitivity. This sensitivity is changed by a switch on the front panel. We can choose from <= 0.25 or <= 0.6V. The amplifier has four RCA line inputs on the back. The rear panel has an RCA line input and power outputs for columns with 4ohm and 8ohm impedance
The amplifier sounds very dynamically, with beautiful deep bass and very good extension on the other edge of the band. He plays a very wide and deep stage. Nothing blends together, no details are lost under the sheer volume of other sounds. The midrange is strong with very good separation of voices, detailed and clean. The nature of the treble is delicate while the bass can play low.
The amplifier's microdynamics are at a high level.
