Bakoon Products HDA-5210mk4 Headphone Amplifier

It was developed with the aim of making headphones sound with the highest sound quality, HDA-5210mk3 It is a new model with mk4 circuit that has further evolved. With the addition of the new HIBIKI-IC to SATRI-IC, the amount of sound thickness information and reality has increased since MK3. When I turned on the power, I got up faster. High impedance current output is also provided. By driving the headphones with current, the distortion is less compared to the voltage drive and it is possible to play more precise. Many headphones have little swell of the frequency characteristics of the impedance, and by using these headphones in the current output, it is possible to listen to many information that cannot be obtained by voltage drive.

The HDA-5210mk4 has a SATRI-LINK current input on the premise that it is combined with the company's preamplifier and D/A converter. In addition, the voltage input of the single series can be combined with other companies' preamplifiers and D/A converters. The amplifier gain is controlled by a 23-step attenuator and can be continuously variable up to 20db. Unlike normal volume controls, there is no deterioration of S/N even if the volume is lowered.

The voltage output adapts to headphones with impedance of approximately 100Ω. The current output drives the headphones with a very high impedance, so the sound distortion is low, and the frequency characteristics change with the impedance curve of the headphone, so it adapts to almost all headphones. The current output gain can be switched by the CURRENT GAIN switch according to the headphone. The current output and voltage output can be used simultaneously. In that case, the output current of the current output is the current flowing into the headphone connected to the voltage output. Therefore, the output current of the current output reflects the personality of the headphones connected to the voltage output. Therefore, the sound changes with the headphones connected to the voltage output.

Very fast to rise, dynamic and powerful bass, realistic, deep vast and silent background and sound field. It is a sound that is different from many headphone amplifiers. With an overwhelming sense of presence and resolution, surprisingly natural playback sound and deep live sound, you won't get tired of listening to it for a long time. It is more comfortable than you can imagine and you can not let go once.
