What reviewers think

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

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.

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:

C6B

  • Positioning: Entry-level line, designed for affordability and compactness.
  • Description: Offers clear audio performance with a ceramic/aluminum driver that provides balanced sound across a compact design. Compared to the F6B, which focuses on enhanced bass response, and the A6B with its Purifi driver, suits small rooms, tight budgets, and straightforward functionality.

F6B

  • Positioning: Mid-range lineup that balances performance and design for home audio.
  • Description: Features an SB fiber/paper woofer that brings dynamic bass response while maintaining overall sonic cohesion. In contrast to the budget-focused C6B and the high-end A6B with its technical precision, offers a versatile option for users seeking moderate price, richer low-end, and adaptable functionality.

A6B

  • Positioning: High-end line aimed at the most demanding audio enthusiasts.
  • Description: Features a Purifi driver that delivers exceptional clarity and detailed sound reproduction. Compared to the C6B's affordability and the F6B's balanced mid-range performance, designed for larger rooms and higher technical demands.

Sonus Faber
Duetto

Reviews

Powerful, rich sound in a compact design. Designed for both digital and analog sources, Duetto is a versatile combination of Italian style and contemporary function. Big sound in a compact design, Duetto marks Sonus faber's inaugural active stereo wireless speaker system. Powered by four bespoke amplifiers, Duetto presents an all-in-one sound solution, harmoniously blending a multitude of connectivity options while keeping the listening experience wire-free.

Double the sound, not the size. Inspired by a harmony produced by two instruments, Duetto sets a new standard for wireless high-fidelity sound in a compact design.

Ultra Wide Band Technology

 Duetto employs Ultra Wide Band (UWB) technology, enabling communication between the two speakers. The wireless transmission avoids latency and interference by other home networks, while guaranteeing a wide frequency spectrum to send data signals at high speeds.

SENSO™ Technology by Sonus faber

 The leather top panel allows the user to control and set up speaker functions — such as playback, volume, input selection, and connections — with a buttonless interface through simple fingertip gestures.

Sonus faber's iconic lute-shaped design takes inspiration from musical instruments. Crafted from wood, the cabinet ensures structural solidity, rich timbre, and musicality, while effectively eradicating internal resonances to shape the unmistakable Sonus faber Natural Sound.

Hear – and see – to believe. Duetto takes note of Sonus faber's most iconic design cues and natural materials.

Sonus Faber is an Italian hifi brand that designs speakers with unique lute-shaped cabinets inspired by traditional violin-making, featuring wood and leather materials to achieve a natural sound. Their speakers incorporate distinctive elements like cork chambers for midrange drivers and asymmetrical driver baskets that mimic natural forms, with each unit being individually tuned by ear to ensure tonal perfection.

Product Strengths

  • Gorgeous sound is clear, smooth, detailed, and dynamic
  • Elegant design is dashingly elegant, minimalist aesthetic, and painstakingly crafted for equal parts style and substance
  • Impressive bass extension and output, described as deep and firm, surprising for their size
  • Clear midrange makes voices sound purposeful, characterful, and entirely present
  • Versatile connectivity with streaming and input options, including Chromecast, AirPlay 2, phono pre-amp, and HDMI ARC/eARC

Product Considerations

  • Some reviewers experienced streaming and HDMI ARC reliability issues
  • Input and control layout can be inconvenient and awkward
  • Prototype unit had operational bugs
  • No bass level adjustment is available, though it could be added in mobile app

Comparisons (according to reviewers)

  • Vs KEF LS50 Wireless II—the KEF LS50 Wireless II is a similarly high-end option
  • Vs PSB Alpha iQ—the PSB Alpha iQ is a more compact wireless speaker package than the Sonus Faber and is comparatively lighter on bass

Takeaway: The Sonus Faber Duetto speakers are well-suited for those seeking amazing sound and a beautiful design in one package. These speakers are easy to connect and use, and fill the room with rich, detailed audio.

Reviews

The Anniversary 10 (A10) is a culmination of all the experience that we have gathered over the last 10 years of designing and building HiFi speakers. Over the last decade, we have produced and sold thousands of speakers to happy HiFi enthusiasts from all around the world. Listening to feedback from our customers, learning from the best and adding our own flavor to the mix, has created extremely popular and critically acclaimed speakers, and now, this has evolved into our best sounding speaker yet. The A10 is something we are truly proud of, both in terms of sound, look and production values. It is a true celebration of our passion for amazing high-end sound, great engineering and high value products.

Buchardt Audio is a direct-to-consumer speaker brand that uses an "upside down" design with a back-mounted passive radiator, which helps create high-end sound at more affordable prices. Their speakers are engineered with advanced measurement technology and a proprietary waveguide design that enhances off-axis listening, while delivering deep bass from compact cabinets that rival larger floor-standing speakers.

Product Strengths

  • Exceptional bass performance for its compact size, with bass that is fast, clear, and tight
  • Multiple 'Master Tunings' offer customizable sound profiles, adapting to different room acoustics and user preferences
  • A high-quality Purifi woofer and SB Acoustics tweeter contribute to clarity, detail, and low distortion
  • A solid wood cabinet made in Denmark provides a luxurious look and feel

Product Considerations

  • Bass output may diminish or be limited at high volumes to protect the drivers from damage
  • A separate purchase of the Platin Stereo Hub may be required for full wireless functionality and room correction
  • The 'Made in China' label applies to the electronics inside the cabinet
  • While the A10 offers impressive bass, some may still prefer to add a subwoofer for a true full-range experience

Comparisons (according to reviewers)

  • Vs Buchardt S400 Mark II, the A10 is more transparent with greater inner detail, clarity, and top-end extension—and deeper, tighter bass—while the S400 Mark II is more relaxed and forgiving with harsh recordings
  • Vs Buchardt A500, the A10 has comparable performance, with possibly a crisper sound in some instances

Takeaway: The Buchardt Anniversary 10 is a compact yet powerful speaker that offers a customizable listening experience. Its impressive bass and versatile tuning options make it a great choice for those seeking a high-quality audio solution in a small to medium-sized room.

Reviews
MoFi Electronics is known for their turntables featuring unique engineering choices like chassis with constrained layer damping and 10-inch tonearms for superior sound quality. Their speakers use concentric driver designs that minimize cone displacement and enhance clarity, while their phono stages offer uncommon features like front-panel adjustability for gain and cartridge load.
Check Amazon
Expand Details

Product Strengths

  • Remarkable sound power and early directivity indexes make it a true point source speaker.
  • Special sound quality for the price offers a level of performance not typically found in speakers at this price point.
  • Very good neutrality is present when the speaker is turned off axis.
  • It is a very versatile speaker to drive.
  • The midrange presentation is very dead center and coherent.

Product Considerations

  • The bass does not reach as low as some listeners might prefer.
  • The speaker can get bright at times.
  • Care should be taken to place it not directly on axis, because when placed directly on axis, it is no longer a neutral speaker.
  • There's no stand included in the package.
  • It is made in China, and construction can be suspect.

Comparisons (according to reviewers)

  • Vs PureAudioProject Duet 15, the SourcePoint 10 is more precise and focused, while the PureAudioProject has a bigger soundstage.
  • Vs Fleetwood Deville SQ, they sounded more alike than different when in action, but SourcePoint was more extended from top to bottom and brought more lively dynamics and impact.
  • Vs Klipsch Heresy IV, the SourcePoint 10 is the superior speaker in every way from build to sound, with more refinement and smoothness, and it seems just as dynamic as the Klipsch.
  • Vs Dynaudio Special 40s, the SourcePoint 10 sounds much bigger, more dynamic, has much better bass, and fills a room with ease.
  • Vs KEF LS50 META, the LS50 sounds smaller, leaner, and not as special in the vocal region.

Takeaway:

The SourcePoint is a speaker with a neutral sound that originates from a single point, and it has remarkable early directivity indexes. It is a speaker that offers very good performance for the money, but careful attention needs to be paid to its placement in the room.

S4b

Reviews

I am the overperforming little guy who will demand your respect after your first audition. I can be a serious 2 channel system with a subwoofer, an LCR, or a surround channel. Effortless dynamics and lightspeed transients remain the common thread of all Signature series speakers including the S4b. A bookshelf with this much technology is hard to find and can literally be the Ninja of any system. Bookshelf, main for a 2.1 system, LCR, Dominus Surround, it can transform into anything you need.

Features including our proprietary DPC-Array controlling Mid/High frequencies and centered by our finest 28mm Beryllium dome and dual 28mm TPCD ultra-lightweight domes. All transducers are developed ground up by our engineers bringing decades of research and culminating in this world class design. All S-Series speakers share the same DPC-Array and benefit from our unique timbre matching technique across the entire series utilizing Beryllium and our advanced Carbon fiber.

These speakers are an acoustic suspension to meet the demands of any listening room with unparalleled dynamic range and musical finesse. Very impressive system alone or when combined with a PERLISTEN subwoofer. Great for use in 2.1 systems or any channel of theater system utilizing subwoofers. Can be used as surround, height or LCR. Bookshelf, stand or on-wall mounting with keyhole or available bracket.

Featuring our DPC-Array as for controlling Mid/High frequencies, centered by our finest 28mm Beryllium dome and dual 28mm TPCD ultra-lightweight domes. This new tweeter/waveguide DPC-Array delivers amazing accuracy, smoothness, and directivity control to handle the critical vocal range and delicate treble. The S4b shares the same DPC-Array and benefits from our unique timbre matching technique as found in the entire S-Series range of speakers. Unparalleled dynamic range, low distortion and musical finesse. The PERLISTEN S4b continues the lineup of speakers that have the distinguished honor to be the world's first and only loudspeakers to be certified for THX Dominus – their highest rating.

Perlisten Audio's speakers feature a unique Directivity Pattern Control array that combines a beryllium tweeter with thin-ply carbon diaphragm midrange drivers to control sound dispersion and enhance imaging precision, and they're the first brand to achieve THX Dominus certification. Their speakers use proprietary thin-ply carbon diaphragm material that's 30% lighter than standard carbon fiber, with their DPC array designed to minimize floor and ceiling reflections while maintaining precise horizontal soundstage.

Product Strengths

  • Solidly built with an inert cabinet, contributing to overall performance
  • Crazy linear/neutral sound from about 100Hz upwards
  • The beryllium tweeter provides nuanced, airy, and extended highs with a hint of shimmer for realistic metallic instruments
  • It creates a three-dimensional soundstage, making the speakers disappear sonically

Product Considerations

  • It does not have a great deal of bass on its own and may require a subwoofer for full-range playback, starting its roll-off at around 100Hz
  • While placement is flexible, a solid amplifier is required
  • The styling might be an acquired taste and could be considered overcomplicated by some
  • The high gloss finishes may not appear different from less expensive speakers, making it harder to justify the luxury price tag

Comparisons (according to reviewers)

  • Vs Bowers & Wilkins 805 D4: The S4B is more neutral/accurate, while the 805 D4 adds bass and treble energy
  • Vs Focal Canta No. 1: The S4B outperforms the Canta No. 1, which has chestiness in its bass and midrange due to its cabinet
  • Vs Revel Studio 2: The S4B reminded the reviewer of the Revel Studio 2, though the Revels had more bass
  • Vs Focal Diablo Utopia: The Perlisten are a great alternative if the Utopias are outside of your reach and are a more neutral and less bright speaker
  • Vs EgglestonWorks Nico Evo: The EgglestonWorks presentation is a little more mid-forward and less 3D than the Perlisten

Takeaway: The Perlisten S4b is a high-performing speaker that offers excellent clarity and a neutral sound, making it a great choice for audiophiles and home cinema enthusiasts alike. The speaker's ability to create a detailed and immersive soundstage can bring music and movies to life.
