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

  • Solidly made
  • SD-card is easily accessible for swapping operating systems
  • Offers many digital links: optical, coaxial, AES, and I2S

Product Considerations

  • Does not have an on-board DAC
  • Performance is equivalent to the Metrum Acoustics Ambre, which may be a consideration for users familiar with that product
  • I2S output is specifically for Sonnet/Metrum products

Comparisons (according to reviewers)

  • Vs Metrum Acoustics Ambre: The Hermes has a different power supply, processing board, casing, and includes a display, with a more purposeful design for audio streaming

Takeaway: The Sonnet Audio Hermes is a well-built streamer with versatile digital connectivity and the flexibility to use different software packages. It is a great addition to a system, especially when paired with other Sonnet/Metrum products.

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.

HERMES is a lightweight, low jitter, bit-perfect plug and play Roon endpoint. Since HERMES is an open platform other software may be used as well.
At Sonnet Digital Audio we are fanatic about building the best Digital to Analogue converters. Because of this dedication to perfection we can truly appreciate listening experiences like Roon. Roon looks at your music and finds photos, reviews, lyrics, and concert dates, and makes connections between artists, composers, performers, conductors, and producers. What you get is a searchable, surfable magazine about your music.

And as we believe a Digital to Analogue converter is the heart of your music setup, what else can we do than to build a ROON end point which will allow you to direct your digital music through our streamer in order to get the most sublime sound available!

The HERMES Digital Bridge is using high quality components and combines it with the user-friendly interface from Roon Labs. Recognized for its perfect timing there hardly is another streamer product available which adds so much detail to music. The HERMES out of the box comes as a ROON certified digital end point, however because of its architecture it is also capable of running different platforms such as DietPi, PiCorePlayer, moOde and Volumio. This allows for even more possibilities such as playing Qobuz or Logitech Media Server content, or even being discovered in a network using UPnP.

We do not believe in "taking prisoners", hence the choice to provide our clients with an open platform. Using our HER...

Brand highlights

Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:

  • Metrum products, including those under the Sonnet Digital Audio brand, are designed around the company's proprietary R2R ladder network DAC chips, known as Transient DAC modules, providing a unique approach to digital-to-analog conversion.
  • The brand is known for its commitment to non-oversampling (NOS) designs, eschewing oversampling and filtering techniques to preserve the naturalness and musicality of audio signals.
  • Metrum implements unique approaches to volume control that maintain signal integrity, utilizing techniques like changing the reference voltage of the DAC modules rather than traditional digital attenuation or analog potentiometers.

Reviews
Nagra Audio, a Swiss brand with roots in professional recording and film (including two Oscars for soundtracks), brings watchmaking-level precision to their hifi equipment through extensive in-house manufacturing of components like transformers. Their HD Preamp and Classic DAC showcase unique technologies, including virtual battery power supplies and PCM-to-DSD conversion, while their commitment to quality is demonstrated by rejecting over half of their tested valves to maintain exceptional standards.
Check Amazon
Expand Details

Product Strengths

  • The Nagra streamer is built from a solid block of aluminum, making it hefty and solid
  • Simple to use, plug and play, and works out of the box with Tidal and Spotify Connect
  • Delivers clarity, resolution, musicality, and an immersive experience
  • Creates a big, three-dimensional soundstage with excellent instrument separation
  • Offers a clean and dynamic sound, providing an emotionally engaging listening experience
  • Ethernet connection is required, as it does not stream via Wi-Fi

  • If one does not have a Nagra DAC, coaxial output is the only option, which has limitations in file quality compared to N-Link
  • Lacks physical controls such as a screen, buttons, or a remote control

Comparisons (according to reviewers)

  • Compared to the HiFi ROSE RS-130, the Nagra streamer has a more natural, liquid, and delicate rendering, while the RS-130 is more punchy, sharp, and incisive with the imaging
  • Compared to the Aurender N10, the Nagra streamer extracts finer details and provides a more three-dimensional, structured presentation, while the N10 sounds slightly fuller and more powerful
  • Compared to the Lumin U2 Mini, the Nagra Streamer provides more air between instruments, stronger bass, better dynamics, and a smoother—more natural sound with an analog feel

Check Amazon
Expand Details

Product Strengths

  • Exceptional accuracy, lifelike tonality, engaging musicality, and very low noise
  • It presents the music with accurate, defined, and nuanced reproduction of timbre
  • Excellent build quality with solid aluminum panels and a high-quality feel
  • The linear power supply provides a generous bass and treble
  • It is capable of decoding all current digital music file formats

Product Considerations

  • The Lumin app, while good, had a couple of minor bugs
  • It needs at least 300+ hours to sound its best, as the sound improved notably after this time
  • The display window on the U2 might be too small for some users
  • Upper midrange slightly recessed, a quality which might suit many an overzealous system
  • Reticent midrange might also account for why the kickdrum lacked some oomph—it might not be the best choice for heavy hard rock or industrial metal

Comparisons (according to reviewers)

  • Vs Bluesound Node: The Lumin U2 offers a more open sound
  • Vs EverSolo DMP-A6: The Lumin will bring a more open sound
  • Vs Lumin U2 Mini: The U2 has much more life, breath and warmth, a more mature sound, more refined over the Mini with more warmth and solidity, and the stage was absolutely amazing, richer, denser, and deeper and has just a bit more magic

Takeaway: The Lumin U2 is an exceptionally well-designed and engineered streaming transport, blessed with neutral and natural tonality. The U2 delivers fantastic sound into systems where it may well be the premier component and set you up for the next decade or more, delivering further free improvements.

  • 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
1999
/
Released
2023
The AirLens™ interface brings perfection to streaming. 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.
Check Amazon
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.
Expand Details

Our Summary

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.

  • Lumin U2 Mini had more resolution, a more clearly defined and expansive sound image, and a riper sound to each musical element, compared to Totaldac's internal streamer
  • Competes closely in performance with the AURALiC Aries G2.1, especially concerning the amount of information and extension of the stage depth

Takeaway: The Lumin U2 Mini is a versatile streamer that delivers high-quality audio and is easy to integrate into existing audio systems. It offers great sound, a user-friendly app, and supports various streaming services, making it a worthy upgrade.
