Deep sound produced by current drive system
MK2 reborn with DC power supply
The HDA-5230MK2 supports only current drive. During the development stage, a SATRI-IC circuit was developed that allows the current drive system to be pulled out directly without passing through a voltage drive circuit, resulting in a smaller product size and more precise operation without conversion processes. Since voltage drive and current drive have completely different sound characteristics, the current drive method provides a unique and attractive sound that is difficult to hear in other amplifiers.
Driving headphones with current results in less distortion and more precise reproduction compared to voltage drive. Many headphones have less undulation in the impedance frequency response, and when those headphones are used with current output, it is possible to hear much more information that cannot be obtained with voltage drive.
On the rear panel is a pair of RCA jacks for input from the source device and aDC power supplyadapter connection terminals, and a single 6.5mm single headphone output terminal is located on the front. The volume stage in the current drive system increases volume in proportion to the impedance size of the receiver, so that at the same volume a 300Ω headphone can be approximately 10 times louder than a 32Ω headphone. For this reason, the current gain adjustment switch on the HDA-5230MK2 is used to set the volume to "HIGH" when connecting to a low-impedance receiver.
The current output drives the headphones with a very high impedance, resulting in low sound distortion, and the frequency response varies with the impedance curve of the headphones, making it suitable for almost all headphones.
The advantages of the HDA-5230MK2 will be more pronounced for those who listen at low volumes. This is because the signal-to-noise ratio remains intact at low volumes and carries a clean signal. This is especially advantageous when listening to large-format classical music, where there can be a large difference in volume within a single piece. As with the company's other amplifiersHDA-5230MK2uses a gain adjustment method that adjusts the amplification value by adjusting the signal's amplification ratio. In this case, the problem of left-right deviation at low volumes can be solved in one fell swoop, not to mention the reduction in signal-to-noise ratio that can occur due to attenuation after amplification.
The result is a very fast start-up, dynamic and powerful bass, a sense of presence, and a deep, vast, and quiet background and sound field. This is a sound that sets it apart from many headphone amplifiers. The overwhelming sense of presence and resolution, the amazingly natural sound reproduction and depth of the live sound will not tire you out even after long periods of listening. It is more comfortable than you can imagine, and once you hear it, you will not want to let it go.
The HDA-5230MK2 is a model that removes the built-in battery from the previous HDA-5230 model, which was a battery-powered model, and instead uses an external DC power supply. This means that the HDA-5230MK2 can be used at home without being limited by battery usage time, and can be used with a portable battery pack when on the road.
