Immense Performance, Unassuming Size
PLENUE D2 Following in the footsteps of PLENUE D, the critically-acclaimed portable hi-fi audio player, the PLENUE D2 was born of even higher specifications and upgraded performance. It's equipped with dual CIRRUS LOGIC CS43131 DACs and boasts high-quality balanced output and Native DSD playback for an even greater level of music appreciation. The stage is set for the perfect performance of the small-yet-powerful PLENUE D2 to once again capture the hearts and ears of music lovers. The Next-generation Premium DAC
New Highest Performance CS43131 As the premier DAC in the MasterHIFI™ line of Cirrus Logic hi-fi audio products, the CS43131 DAC offers an unparalleled level of performance. CS43131 is a high-performance DAC with a built-in high-resolution headphone amplifier. The next-generation premium DAC merely sips battery power while delivering the best audio output. Dual-DAC Design for
Clear, Noise-Free Sound The PLENUE D2 is equipped with two top-of-the-line CS43131 DACs to bring you one step closer to analog sound.
The digital input signal is converted by each discrete DAC, providing listeners with perfect sound as close to the original recording with zero noise.
High Quality Balanced Out
Maximum Output of 4.0Vrms 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 D2 strengthens the output signal for clearer and crisper reproduction of original sound.
The PLENUE D2 uses 2.5mm balanced output to reproduce crisp original sounds.
Supports Native DSD for More Natural Sound DSD(Direct Stream Digital) is a high quality Super Audio CD format that processes signals at 2.8224MHz per bit.
The technology carries the maximum sound information possible to reproduce the delicate and crisp sound of analog.
To realize the best possible sound quality, the PLENUE D2 reproduces DSD in Native method and supports DSD128.
True Original Sound
24bit/192kHz High Resolution Sound 24bit/192kHz source recorded in studio provides the best sound, it has no signal loss and has outstanding resolution.
Enjoy a true HD Sound using 'PLENUE D2' that plays artist and engineer's intended sound without missing a single detail.
The Best Sound Performance for HD Sound
SNR 130dB, THD+N 0.0004%, Balanced Output 4.0Vrms The amazing specifications of the PLENUE D2 include SNR 130dB, THD+N 0.0004%, Stereo Crosstalk -143dB,
and Balanced Output 4.0Vrms which are the result of our decades of audio experience and passion for perfection.
The PLENUE D2 was created through our relentless effort to deliver perfect sound quality to listeners anytime and anywhere.
  • 130dB 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.
  • 0.0004% 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.
  • -143dB 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.
  • 126dB
  • 0.0004%
  • -124dB
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 118dB has a loss of more than 2 quantization bit in digital signal, which leads to four times the amplitude resolution difference comparing to PLENUE D2 with 130dB. 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 D2 covers from basic specifications to advanced ones offering enhanced enjoyment of listening HD Sound to users.

Beyond the Limits of Hearing
Premium Sound DAC Filter Five digital filters (Fast/Low-latency, Fast/Phase-comp, Slow/Low-latency, Slow/Phase-comp, Non-oversampling) are provided to enable
fine micro-tuning. This empowers listeners to tune sounds previously beyond the limits of hearing even with identical sound sources.
Normalized Amplitude (V) Time (μs)
  • Fast/Low-latency
  • Fast/Phase-comp
  • Slow/Low-latency
  • Slow/Phase-comp
  • Non-oversampling
45 Hours Music Nonstop Playback PLENUE D2 uses a power-saving DAC that minimizes battery consumption and a high-performance battery
that delivers up to 45 hours of MP3 playback or 30 hours of HD audio from a single charge.
High-Output Mode for
High-Impedance Headphone Users New to the PLENUE D2 is a high-output headphone
mode to properly drive high-impedance headphones.
High-end, high-impedance headphones can be driven
without a separate headphone amplifier for greater
flexibility when used in combination with various receivers.
Another Criterion for Perfect Sound
JetEffect 5 & BBE+ JetEffect 5 and BBE+ combine to correct sound distortions and phase caused by either the physical limitations of a receiver or the listening environment and reproduce sound closest to the original studio recording. In addition, users can create their own optimal sound according to their personal preferences via the use of BBE+ and EQ filters.
5 Band EQ Filter Advanced settings to adjust the frequency and width of each band.
BBE High-definition effects to sharpen sound. (Phase correction)
Mach3Bass Bass booster to enhance super low-end bass.
3D Surround Three-dimensional sound for an enhanced sense of space.
MP Enhance A feature for compensating lost sound segments.
Reverb* A reverb effect for enhanced realism

The Best Choice for
Original Live Sound Reproduction, BBE+ Sound includes a unique high frequency harmonics, and this unique harmonics pattern helps users to distinguish the each instrument. This high frequency harmonics reach our ears earlier than the normal frequency in live sound. Human brain recognizes earlier signal as more important signal, therefore high frequency harmonics is vital component in music. However, like speakers, headphones, and earphones, receivers tend to delay high frequency range rather than low frequency range, resulting in decrease in clarity and reality. Normally, equalizer or tone control is used to increase clarity and reality in sound, however this method cannot remove the delay of high frequency range to reproduce the natural sound. By applying BBE, phase characteristics of lower and middle frequency bands can be delayed comparing to high frequency band, resulting high frequency reaches human ears earlier than any other frequencies to make the same condition as live sound. Also, by gently expressing high and low frequency range, very dense and clear sound can be reproduced.
