The Shanling ECZero AKM is a portable CD player that offers a range of features beyond just playing CDs. It's a versatile device that can rip CDs to USB drives, transmit wirelessly via Bluetooth, and provide balanced and unbalanced headphone outputs. It also includes digital coaxial/optical outputs for CD transport deployment, making it a powerful tool for audio enthusiasts.
One of the key features of the ECZero AKM is its solid-state design, which sets it apart from its predecessor, the ECZero T. Shanling has replaced the tubes and R2R DAC with an all-solid-state design built around an AKM AK4493S DAC and SGM8262 op-amps. This design choice offers a different sound experience compared to the tube-equipped model, providing a more straightforward and modern approach to audio playback.
In terms of performance, the ECZero AKM delivers impressive results. The front-mounted 3.5mm headphone jack can push 525mW into 32 Ohms, while the balanced 4.4mm headphone output delivers 836mW per channel into the same load in high gain. These specifications suggest that the device has sufficient power for most headphones, although Shanling has reportedly lowered the output impedance to make it more compatible with in-ear monitors (IEMs).
The device also includes line-level connections, including a 3.5mm line out, 4.4mm balanced line out, and a 3.5mm combined coaxial/optical SPDIF socket for digital connections to external DACs. The 1.68" color LCD display keeps things simple, showing track info, playback status, and volume level. Physical buttons control transport functions, while a volume slider manages the 100-step digital attenuation across three selectable gain modes.
The ECZero AKM measures 158 x 150 x 28mm and weighs 575 grams. Its metal housing with tempered glass covering the disc mechanism provides a sturdy and durable feel. The disc mechanism employs magnetic pressure to stabilize the CD during playback, reducing vibration and minimizing read errors, which is crucial for portable use.
The device is powered by a 5500mAh battery, which promises ten hours of portable playback. USB-C charging replenishes the cell, and the same port accepts external power for desktop use. Bluetooth 5.3 opens wireless streaming options, supporting SBC, aptX, and aptX Adaptive codecs. However, the absence of AAC and LDAC means that AirPods users and Sony headphone owners may have limited options.
One of the standout features of the ECZero AKM is its CD ripping capability. The process happens in real-time playback speed, so ripping a 70-minute album takes 70 minutes. The device supports various file formats, but users need to tag their files manually after ripping. This feature is a boon for archivists and collectors who want backup copies of their physical media.
The ECZero AKM also doubles as a capable desktop DAC for computer audio. The AK4493S DAC's support for PCM up to 32-bit/768kHz and DSD256 is particularly useful when streaming high-resolution files from a computer. This overspecification for CD playback becomes a genuine feature for USB DAC mode, ensuring optimal performance regardless of the source material.
In terms of pricing, the ECZero AKM is priced at US$319, which is US$240 less than the tube-equipped ECZero T at US$589. The price difference reflects the trade-off between solid-state simplicity and tube warmth, and whether this trade-off works depends on individual sonic preferences and budget constraints.
Despite the potential for portable CD players to make rational sense in 2025, the bigger question is whether enough nostalgic audiophiles exist to sustain this curious revival. The ECZero AKM offers a range of features that cater to audio enthusiasts, but its success will depend on the demand from audiophiles who appreciate the nostalgia and functionality it provides.
