PLENUE 2: The World's First 2

The PLENUE 2 offers an unprecedented level of audio that delivers an unforgettable listening experience. The latest premium DAC AK4497EQ for optimized audio quality, SoundPlus amplifier integrated with newly improved technologies, Dual Control Wheels re-designed for the ultimate user experience, ultra-precise Dual TCXO for accurate and detailed sound reproduction, balanced output for clear, high-quality sound, and upgraded design to match its powerful performance.
Sweeping changes using innovative technologies. Experiencing the performance of PLENUE 2 leaves audiophiles and casual listeners alike in awe.

The Latest Ultra-High-Quality Premium DAC

AKM's latest AK4497EQ DAC equipped with high-end audio equipment is a premium, high-performance, state-of-the-art successor to the AK4490 DAC. It minimizes noise and distortion and faithfully reproduces high-resolution audio via AKM Premium Sound technology, pushing audio DAC performance to its very limits. The PLENUE 2, featuring the AK4497EQ DAC with specifications and characteristics on par with and even exceeding the highest standards of audio equipment, vividly reproduces sound that most closely mirrors the original and handles audiophile-quality 24bit, 192kHz lossless/uncompressed as well as DXD and DSD sources.

Core Technology and Philosophy
AKM Premium Sound Digital Filter

The PLENUE 2 is equipped with the AK4497EQ DAC featuring the AKM Premium Sound architecture that utilizes a large circuit area to improve current flow, allowing you to fine-tune the sounds using a wide range of digital filters. Six 32bit, 8x digital filters (Short Delay Sharp, Short Delay Slow, Sharp, Slow, Low-Dispersion Short Delay, and Super-Slow) are provided to enable fine micro-tuning and allow implementation of transient signal responses in the time domain. This empowers listeners to tune sounds previously beyond the limits of hearing even with identical sound sources.

High-Performance SoundPlus Amplifier for Sound Perfection

One requirement for achieving perfect sound is a high-performance amplifier that is optimally compatible with high-end receivers. Texas Instruments' high-performance SoundPlus amplifier delivers high voltage while maintaining the highest level of linearity—a significant step up in audio technologies from existing versions of amplifiers. With a maximum output of 2Vrms, the amplifier generates powerful performance capable of driving high-end headphones with high impedance without the need for a separate headphone amplifier. Now, sophisticated and precise sound tuning makes it possible to clearly express any frequency range in combination with a variety of receivers.

Closer to the Original Sound,
Native TX DSD

The PLENUE 2 transmits native DSD data to the DAC in serial, perfectly converting audio signals and reproducing DSD sources using a Native TX DSD method. The crystal clear, delicate qualities of high-resolution DSD sound sources are better realized than ever before.

Dual Control Wheels,
The New Standard for Analog Wheels

We approached analog wheels from a totally different perspective. We designed Dual Control Wheels that offer users a variety of experiences--the Volume Wheel for incremental adjustments to sound and the Multi Wheel that controls other analog functions. The wheels are located on the top of the device to prevent accidental adjustments during handling while allowing positive control of volume and other functions. The Multi Wheel on the left conveniently controls functions related to music listening and device operation, while the Volume Wheel on the right allows the volume to be fine-tuned (140 steps in 0.5dB increments).
The PLENUE 2's Dual Control Wheels are the future of analog wheels.

Multi Wheel for Diverse Listening Environments

The Multi Wheel controls analog functions for the utmost listening experience in every environment. With the Multi Wheel, it's easy to change the DAC filter or JetEffect presets, as well as previous/next song, rewind/fast-forward, and screen brightness in a whole new way.

Artisanal, Alluring Wheel Lights

Circular LEDs are located underneath the Dual Control Wheels, emitting a gentle light during wheel operation. The result of high-tech mechanical design, the circular wheel lights on the PLENUE 2 convey an unrivaled commitment to craftsmanship.

The World's Best Audio Quality
SNR 123dB, THD+N 0.0005%

The amazing specifications of the PLENUE 2 include SNR 123dB, THD+N 0.0005%, and Stereo Crosstalk -139dB, which are the result of our decades of audio experience and passion for perfection. The PLENUE 2 was created through our relentless effort to deliver perfect sound quality to listeners anytime and anywhere.


SNR (Signal to Noise Ratio)

SNR, or signal-to-noise ratio, is a measurement for indicating how much noise is mixed into an audio signal. A high SNR value means a clearer, noise-free original studio sound.


Stereo Crosstalk

Stereo crosstalk indicates the degree of interference between left and right channels caused by electromagnetic induction. A low stereo crosstalk value means less inter-channel interference for a clear separation of left and right channels.


THD+N (Total Harmonic Distortion+Noise)

THD+N is an indicator of signal distortion caused by various factors, including harmonics. A small THD+N value means a reduced occurrence of harmonic distortion on an audio device.




The ultra high precision clock precisely matches the 44.1kHz and 48kHz series sound.

High SNR, Indispensable Element for HD Sound

When we hear the music, acoustic signal picks up unavoidable noises as the signal processes to the output, the process leads to distortion in the original signal. This phenomenon can be expressed as a numerical value of SNR (Signal to Noise Ratio). SNR compares the level of a desired signal to the level of background noise. It is one of key criteria that can be measured to compare acoustic performances between one to another. If there is a difference of 6dB between two devices, there is a difference of 1 quantization bit in digital signal. For example, the device with 113dB has a loss of more than 1 quantization bit in digital signal, which leads to twice the amplitude resolution difference comparing to PLENUE 2 with 123dB. Therefore, to fully enjoy the HD Sound, a device must have excellent SNR figures. Having a poor SNR or THD means the device performs imperfect reproduction of the 24bit source, so there is no difference between playing 24bit source and 16bit source. COWON processed through intensive research and development period to achieve the best SNR, THD etc. PLENUE 2 covers from basic specifications to advanced ones offering enhanced enjoyment of listening HD Sound to users.

Ultra-Precise Dual TCXO Clock for Perfect Accuracy

44.1kHz and 48kHz sound sources, staples in the music industry, are adjusted most accurately via dual ultra-precise temperature-compensated crystal oscillator (TCXO) clocks with 1.0ps of phase jitter to reproduce the most accurate sounds. High-resolution sound is perfectly and finely reproduced in every circumstance thanks to stable, error-free operation even when exposed to thermal extremes caused by prolonged device operation or temperature and voltage fluctuations in the surrounding environment.

High Quality Balanced Output

Balanced output effectively blocks noise generated when signals are transmitted by adding 'out of phase' signals to unbalanced output signals. Since it transmits two types of signals simultaneously, the PLENUE 2 strengthens the output signal for clearer and crisper reproduction of original sound. The PLENUE 2 uses balanced output to reproduce crisp original sounds.

Tuning the Physical Limits of Space-Time
World's Renown Professional Sound Control, JetEffect 7

Speakers, headphones, and earphones tend to delay the high-frequency band more than the low-frequency band, even in original sound sources. When facing these phenomena, JetEffect 7 and BBE+ compensate the physical phase to reproduce vivid original sounds like a live performance and provide optimal HD sound via sophisticated methods and controls. BBE+, Reverb, and Chorus can be freely adjusted, as well as the 10-band EQ filter for fine, frequency-specific control. The PLENUE 2 responds to various listening conditions by realizing precise tone control to suit each listener's personal preferences via 66 presets including 16 user presets. Crisp, high-density audio that best reproduces the live sound of original source is now possible through BBE+ with phase correction.
JetEffect 7 provides listeners with the finest hi-fi audio regardless of where the music is played, what receiver is used, and which genre of music is preferred.
