YAKUZA — The Audio Processor That Plays by Its Own Rules

YAKUZA audio processor isn’t about boring numbers, graphs, or watts.

It’s about sound that grabs you from the first second.

About a warm, rich, enveloping tone that makes you want to keep listening to music over and over again.

We didn’t chase kilowatts on paper — we chased the feeling.

A feeling where the vocals send shivers down your spine, the guitar sounds alive, and the kick drum hits your chest like it should.

- Premium-class RCA pass-throughs — so not a drop of sound is lost when it matters most.

- Uncompromising signal quality inputs: 192kHz optical/coaxial/HDMI 2.1.

- Built-in processor — full customization for any audio system.

YAKUZA’s philosophy: Sound not for everyone, but for a lifetime.

After listening, you’ll never want to go back to "ordinary" processors.

========

1. The power amplifier section is built with TPA-3251 Class D amplifiers, powered by 35 Volts. These amplifiers have rightfully earned the trust of the most demanding listeners in home audio.

2. The processor can operate in pure processor (pass-through) mode with 12 channels.

3. YAKUZA comes standard with our premium USB AUDIO board featuring the XMOS HU777 chip.

4. RedPower is transitioning to the modern new HDMI audio standard, supporting up to 5.1 Dolby DD+.

5. A high-precision clock generator is installed as standard. (2025 model year).

An extremely important detail. (see image)

6. HI-FI operational amplifiers AD8620 are installed. For more detailed information about these operational amplifiers, you can find it online.

Analog Devices AD8620

Type: Precision JFET-input operational amplifier.

Feature: Extremely high input impedance and zero input offset current.

Power supply: ±5 V to ±18 V.

Sound performance: Highly musical, soft, and warm, yet slightly less detailed compared to the OPA1612.

Applications: High-quality audio equipment, especially where input currents are critical and a "valve-like" presentation is required.

Hi-Fi and portable audio players: Frequently used in older high-end players such as iBasso and Astell&Kern (especially custom versions) to achieve a smooth presentation.

Headphone amplifier modding: A popular chip for replacing stock op-amps to deliver a more "lively" sound.

Audio card tuning (especially in the 2000s): Audiophiles often swapped standard NE5532 chips with AD8620 to add warmth and enhance soundstage.

Tube-transistor hybrids: Utilized to emphasize the "valve character" in circuits, where the JFET input further softens the transients.

Typical use case: When a more musical, cozy sound is desired, rather than cold sterility.

7. All interfaces support 192kHz (optical, coaxial input, HDMI).

8. Japanese ELNA audio capacitors are installed.

9. Supports 5.1-channel sound and movie playback with channel mapping. Automatically switches to 2.0 audio preset when changing playback files.

10. No remote control required when installed with Redpower car stereos! Steering wheel buttons for volume control are retained, while you enjoy a pure signal.

11. The audio processor can be configured without a computer — simply connect a USB to the car stereo.
