Bakoon Products HDA-5230MK2 Compact Headphone Amplifier

The HDA-5230MK2 is a compact headphone amplifier that supports only the current drive method, developed by Bakoon Products (currently SCL), which has built a unique position in the world of analog audio.

The core of this machine is the SATRI-IC circuit that derives the current drive method directly without passing through the voltage drive circuit. This revolutionary circuit design enables more precise operation without a conversion process, producing sound characteristics with less distortion and more information, which is completely different from voltage drive.

The true value of headphones brought out by the current drive method (SATRI-IC)

Overwhelming resolution and quiet background

By driving headphones with very high impedance, the HDA-5230MK2 reproduces a lot of information that cannot be obtained with voltage drive.

The current drive method provides a sound that stands out from many other headphone amplifiers. The sound is live sound with an overwhelming sense of presence and resolution, surprisingly natural playback sound, and depth, so you won't get tired of listening even if you listen to it for a long time.

• Low distortion and vast sound field: It has a very fast start-up, dynamic and powerful bass, and a sense of presence, providing a deep, spacious and quiet background and sound field.
• Maintaining signal-to-noise ratio: The benefits are noticeable for those who listen at low volumes. Since the SN ratio is maintained even at low volumes, even in songs with large volume differences such as large-scale classical music, problems with left-right deviation and decreases in the SN ratio at low volumes can be solved at once.

This more comfortable sound experience than you can imagine,Once you listen to it, you won't be able to put it downIt's full of.

This model is a model that removes the built-in battery from the previous model HDA-5230, which was equipped with a battery, and changes to an external DC power supply specification. This increases the flexibility of use at home.

[Long Review Summary] An experience where the HD800S dramatically changes

Soft sound expression that brings out the true character of the receiver

The reviewer mentioned that when connecting the reference device SENNHEISER HD800S to the HDA-5230MK2, **“I was surprised by sound completely different from what I had heard on the receiver before.”**

• Dramatic bass change: Even in songs they usually listen to, **“rich bass that I’ve never heard before”** resonates. It is emphasized that there is no unnaturalness like an EQ boost; it is expressed naturally as if it had always been that way.
• Relationship between impedance and tone: The current-drive method has the characteristic such that headphones sound emphasized in high-impedance frequency ranges. Due to this characteristic, the HDA-5230MK2 is notable in how **“its character completely changes”** depending on the connected receiver.
• Direction of sound quality: The overall sound texture is described as being closer to **'softness' rather than sharpness. Compared to the HD800S, although it has approached a V-shaped sound signature, it offers a 'non-aggressive sound that is easy to listen to for long periods without fatigue,' suggesting strongly that if your system sounds harsh, the HDA-5230MK2 could be the solution.**
