What reviewers think

Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.

Product Strengths

  • Significantly lowers the noise floor, creating a 'black void' sonic background, resulting in a cleaner, clearer, and more refined sound
  • Improves spatial holography, increasing three-dimensionality and separation in the soundstage, contributing to a more natural and organic sound
  • Universally improves clarity and soundstage size, precision, and tone trailing
  • Well-built with a machined aluminum case and compact size

Product Considerations

  • Only has a single I2S digital output, limiting its compatibility to DACs with I2S inputs
  • The included power supply is considered inadequate, and reviewers recommend an upgraded aftermarket linear power supply
  • Improvements may be less dramatic on high-performance DACs that already have good clocking and noise suppression

Comparisons (according to reviewers)

  • The Live Harmony DAC, with the µDDC, can reach a similar performance level as the Denafrips Venus 15th

Takeaway: The Harmony µDDC can enhance the sound quality of a system by cleaning up the digital signal, improving soundstage, and lowering the noise floor. This device could bring out the full potential of music for those who have a DAC with an I2S input.

What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

Our take on the brand

Laiv offers stunningly built hifi products at prices almost as attractive as the products themselves. Their Harmony and uDAC R2R DACs feature discrete R2R digital to analog converters with the option to run NOS (Non-Oversampling). And their HP2A amplifier is one of if not perhaps the most powerful commercially available headphone amplifier, delivering over 60 volts of output, and over 25 watts into 32 Ohms as tested by Cameron.

Our summary

Product Strengths

  • Excellent build quality with a luxurious aluminum body and sleek design
  • Serves as a high-quality preamp, streamer, and DAC all in one device
  • The DAC utilizes flagship AKM chips with 'Velvet Sound' technology, providing a warmer, richer, and more natural sound compared to the DMP-A6
  • User-friendly interface with a responsive touchscreen and a well-designed control app
  • Versatile connectivity options, including multiple digital and analog inputs/outputs, and support for various streaming services

Product Considerations

  • The preamp section's performance is not on par with the digital streaming and DAC sections
  • DSP functions are limited up to 192k sampling rate
  • Spotify Connect has a lag in song switching at times
  • The HDMI output is dedicated to I2S output, omitting the multichannel output capability of the DMP-A6
  • Playlists cannot span music libraries; it is not possible to mix music from an internal SSD with tracks from TIDAL

Comparisons (according to reviewers)

  • Vs DMP-A6: The DMP-A8 has better resolution, refinement, separation, and bass, sounding more 'analogue', while the A6 sounds brighter, lighter, and drier
  • Vs HiFi Rose RS250a: The DMP-A8 sounds better if richness, warmth, and a big soundstage are valued, while the RS250a is preferred if analytical detail and an open top end are most important
  • Vs Lumin U2 Mini: As a streamer only, the A8 is about the same as a Lumin U2 Mini but not quite up to the level of a Lumin U2 or HiFi Rose RS130
  • Vs Geshelli Labs J2S AK4499 DAC: The sound was noticeably improved
  • Vs RME ADI2 Pro: The DMP-A8 was preferable, as it sounded less flat and more three-dimensional in comparison

Takeaway: The DMP-A8 is a well-built and versatile streaming DAC that offers a rich and natural sound, along with a user-friendly interface and plenty of features. It is a great choice for audiophiles looking for an all-in-one solution to elevate their music listening experience.

PS Audio
AirLens

Reviews

Streaming audio via Roon or other services like Qobuz, Tidal, and Spotify offers millions of titles at the touch of a finger. Unfortunately, connecting your sensitive DAC to the noise generated by computers, routers, NAS, local networks, and modems via either WiFi or Ethernet cable is not a great-sounding solution to bringing high-performance audio into your listening environment. The PS Audio AirLens™ completely eliminates the problems of noise, jitter, and EMI influences through complete galvanic isolation and perfect reclocking of the digital audio signal. You’ve not yet heard how great streaming can sound until you experience audio through the AirLens.

PS Audio is a well-known American brand with a strong following among enthusiasts, due in part to the educational YouTube videos produced by its founder. The company offers products across a wide range of categories, each developed with input from top engineers, resulting in unique sonic signatures. PS Audio’s offerings frequently appear on top 10 lists from professional reviewers, with many products recognized for their high-quality performance and innovative design.

Product Strengths

  • Both an input stage and a galvanically isolated reclocking output stage ensures 100% isolation and noise-free delivery of perfect digital audio signals
  • A DC-to-DC converter that is galvanically isolated allows the input and output stages to be completely isolated, allowing each to function as its entity electrically
  • PS Audio uses its 'Digital Lens' technology to ensure the DAC gets the best audio data possible by storing data in a variable RAM buffer and sending it to the precision clocks within the AirLens
  • The AirLens excels in performance with the I²s connection, delivering musical realism as well or better than any streamer under $5K
  • The unit has a smaller frame component
  • USB or Toslink inputs are absent

Product Considerations

  • The PS Audio AirLens cannot stand toe-to-toe with the HiFi Rose RS-130 when it comes to design or features, as it is a basic box with no display screen
  • There isn't a place to hook up a hard drive if one wants to stream stored music, since it is basically a streamer only
  • The AirLens does not have a DAC
  • It is not for the mainstream-streaming, non-audiophile consumer who uses Spotify and Apple Music, since it does not cater to features that audio enthusiasts will not use, such as AirPlay2, Bluetooth, or a proprietary music management application

Comparisons (according to reviewers)

  • HiFi Rose RS-130: The Air Lens does the 3D imaging thing better than the HiFi Rose, however, the HiFi Rose has a more meaty—punchy—refined analog kind of sound overall
  • EverSolo DMP-A6: The PS Audio Air Lens far excelled above the A6 when it comes to sound quality, as the A6 sounded a little more digital in the treble area with grain and noise
  • WiiM Pro Plus: Going from the WiiM Pro Plus streamer into the Denafrips DAC to the Air Lens, there is an increase in bass and energy in the holographic sound stage
  • HiFi Rose RS250A, NAD C 700, Naim ND5 XS 2: The HiFi Rose RS250A, the NAD C 700, or even the Naim ND5 XS 2 all have Bluetooth and a DAC in their system, the AirLens does not

Takeaway: The PS Audio AirLens is a music streamer designed to eliminate digital noise and hash and bring an experience unlike most streamers on the market. It's perfect for audiophiles who want a simple, high-quality streamer that delivers exceptional sound.
