- Outstanding customer service is available
Product Considerations
- Does not have a built-in DAC, requiring an external DAC for audio output
- Roon is not fully supported as a RAAT device, only as an Airplay device
- The Android version of the control app may not be as user-friendly as the iOS version
- HDDs/SSDs not included, so the cost of storage is not part of the overall price
- The Aurender N20 does not offer a hardware remote, which might be a problem for some users
Comparisons (according to reviewers)
- Vs Aurender A20: The N20 is a superior streamer for upscale rigs due to its dedicated functionality and higher parts quality, whereas the A20 is an excellent choice as a streamlined hifi
- Vs Aurender W20SE: The reviewer believes the sweet spot in the Aurender lineup is the N20 unless dual AES output is needed, in which case—the W20SE would be better
- Vs Small Green Computer CAPS 20.1: The Aurender N20 is a state-of-the-art server with great sound quality for plug and play, while CAPS 20.1 needs maintenance
- Vs Linn Klimax DSM/3: Unlike the Linn Klimax DSM/3, the N20 comes with two internal hard-drive storage bays
Takeaway: The Aurender N20 is a well-designed music server/streamer with high-quality sound that offers a streamlined user experience and integration of various digital audio functions. It is a solid choice for audiophiles seeking simplicity, stability, and excellent sound quality in a digital source component.

Our take on the brand
The KALA 50 is the flagship of the KALA range, with an electronic design that is derived from the Kala 50, delivering compelling musical performance at a more affordable level. Every panel in the KALA 50 is precision machined from a thick solid plate of premium alloy for a perfect fit and finish, and outstanding vibration control.
Our summary
Product Strengths
- Robust and solid build quality
- Excellent sound quality, reproducing music with high fidelity
- Gives music life, verve, vigor, and emotional involvement
- Antipodes optimizes the power supplies to increase speed and lower noise
- Offers a platform for the best available applications
Product Considerations
- The burn-in process can take a long time
- Worldwide chip shortages forced a few changes to the design, and the beta software would not be bug-free
- The USB output is considered the worst in terms of sound quality and receives the least amount of isolation and reclocking
- Removing Roon local option can be a problem for some users
Comparisons (according to reviewers)
- Vs. Aurender N20: The K50 replaced an Aurender N20
- Vs. Innuos Statement: The Innuos Statement has a warm and smooth signature
- Vs. HiFi ROSE RS150b: The K50 provides interconnectedness between sounds that the HiFi ROSE does not
- Vs. Antipodes K41 and K22: Combining an Antipodes K41 and K22 will make for a two-box K50 if one is so inclined
Takeaway: The Antipodes K50 is a well-built music server that brings soul back into a digital system. It creates a natural and inviting sound that can help you rediscover your favorite music.

Our take on the brand
Our summary
Product Strengths
- Achieves ideal isolation for best performance using PLINK, PDFAS clocking technology, and separate chassis with high-quality linear power supply
- Offers superb sound quality whether streaming from UPnP or using local or streaming Roon RAAT sources
- Delivers a neutral, fast, lively, and expressive sound that is also finely nuanced, fluid, spacious, and gently svelte
- Has a direct, rhythmic, fast, pure, and impactful sound, combined with deep tonal saturation and an enveloping soundstage
- The MPS-X is designed to allow multiple clock signals for the streamer, network bridge, etc, but it then re-clocks all digital signals through the proprietary high-precision clock generator before sending the signal out to the DAC via its fiber optical interface (PLINK)
Product Considerations
- PLINK is not 100% compatible with Nagra Link, there is skipping/glitching on certain sample rates
- Aftermarket feet could alter pacing and drive, so it is best to start with the MPS-X's own feet
Comparisons (according to reviewers)
- Compared to Aqua LinQ, the MPS-X excels in being liquid, free-flowing, and spacious, particularly possessing more distinct layering in the depth plane, while the Aqua LinQ is more immediate and direct
Takeaway: The MPS-X offers excellent streaming audio performance with great sound quality and isolation, improving the sound of music servers and offering further potential within a Playback Designs system. It is an expertly crafted device that should make listening to music even more enjoyable.

- Equipped with the AKM 4490 DAC chipset, known for musicality and a rich, smooth sound
- Comes with the Aurender Conductor app, which is simple, intuitive and stable for browsing and control
- Uses a caching system with a 240GB SSD to ensure stable playback and minimize stress on storage drives
Product Considerations

- May be overkill for casual listeners

Takeaway: The Aurender A200 is a versatile digital audio solution that offers a combination of excellent sound quality, user-friendly software, and flexible storage options. It could be the perfect choice for audiophiles seeking a streamlined and high-performance music server and streamer.

Video review
Our take on the brand
