How useful are hifi reviews? We consider them useful for three things: (1) Surfacing new products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've ever heard (this means they probably are legitimately great). (3) Identifying a product's unique attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we  discount what reviewers say because they heap praise on everything—rarely being negative for fear of souring relationships with manufacturers. Further, they seldom have more than a couple products on-hand at once, relying on their imperfect memories to compare to past products.

Borresen
The M3 speakers are the perfect blend of form and function, which reflects the excellent and highly productive partnership between two great minds in the audio industry – Michael Børresen and Flemming Erik Rasmussen. The sleek and elegant design of these speakers, combined with their outstanding audio performance, makes them a testament to Audio Group Denmark's commitment to audio excellence.
Check on Amazon
Børresen Acoustics stands out for its iron-free magnetic motors and cryogenically treated metal components, which reduce inductance for clearer sound. The brand's speakers feature unique elements like zirconium-based 3D-printed baskets and a patented ribbon tweeter design, combined with series crossover networks for phase-locked electrical current across frequencies.
Expand Details

Our Summary

Product Strengths

  • The M3 presents music with an unprecedented degree of individuality and specificity, without sacrificing tonality, texture, or body
  • Remarkable level of resolution
  • Astonishing transparency and is resolute
  • Accurate tonality and represents timbre faithfully
  • Exceptional high-frequency detail and speed due to a planar tweeter
  • Accepts only banana terminations

Product Considerations

  • The planar tweeter misses the very last measure of extension, shimmer, and effortlessness accomplished by the very best available today
  • Low-frequency extension was limited to the high 20 Hz, low 30 Hz range

Comparisons (according to reviewers)

  • Compared to Magico M9, the M3 has recalibrated the resolution yardstick by which all other loudspeakers must be measured and compared
  • Compared to Von Schweikert Audio ULTRA 9s, the M3 has recalibrated the resolution yardstick by which all other loudspeakers must be measured and compared

Takeaway: The Børresen M3 loudspeakers boldly represent the realization of striking potential in audio and push known boundaries. People who choose the M3 will enjoy a specific level of playback that is unavailable from other loudspeakers.

Alexx V

Released
2021
Wilson Audio
The original Alexx loudspeaker, launched in 2016, quickly gained critical acclaim throughout the industry. Alexx benefited from several elements developed during the five years Wilson Audio's founder David A. Wilson, and his unwavering R&D team, brought to life his magnum opus: the WAMM Master Chronosonic. Now, five years after the monumental accomplishment of the WAMM, Alexx V builds upon the original Alexx's success by offering a completely re-engineered performance envelope without greatly increasing the footprint. Comparing the overall size of Alexx V to the original, Alexx V is only 1" deeper and 1" taller while maintaining the same width.
Check on Amazon
Wilson Audio is often considered the quintessential American high-end hi-fi brand, a staple in premium audio dealerships across the country. Many reviewers use Wilson speakers in their own home systems, reflecting their reputation for outstanding dynamics, bass depth, and the ability to reproduce classical music with remarkable realism. Wilson focuses on creating an uncolored sound, aiming to replicate the experience of live, unamplified performances.
Expand Details

Our Summary

Product Strengths

  • Sublime image size and expansiveness, coupled with an ability to be driven as hard as your ears or your amps can take
  • A sense of balance to the sound of the Alexx V makes renewal possible, expressive and articulate from the deepest bass to the highest treble
  • Trickle-down benefits from the WAMM Master Chronosonic and Chronosonic XVX
  • Bass performance is otherworldly
  • The Alexx V has the ability to uncover and continue to deliver micro-details at extremely high SPLs, even after that slam of a transient

Product Considerations

  • Some power behind the throne is needed, because the loudspeaker's impedance plot drops to two ohms at 250Hz
  • The dome tweeter does sacrifice the last ounce of micro-detail, compared to the insane resolving power of the best diamond and beryllium drivers
  • The choice of finish needs to be considered with care
  • Cable management can impact performance

Comparisons (according to reviewers)

  • Compared to the original Alexx, the Alexx V is a massive improvement—closer to a baby XVX in so many ways
  • Compared to the Alexia 2, the Alexx V was more than a mere additive sum, a step-function improvement
  • Compared to the Wilson XVX and WAMM Master Chronosonic, the tweeter is effortless and resolving by normal standards, but no match for the extraordinary levels of detail retrieval

Takeaway: The Alexx V offers a sublime listening experience with excellent balance and dynamic range that allows the listener to get closer to the music. It is a worthy contender for those looking to upgrade their listening experience.

Product Considerations

  • The midrange dome is exposed, which might be a concern with children
  • Owners of previous Linn systems may find the price difficult to accept
  • Some audiophiles may prefer Linn to trawl its past rather than building its future, and they will want an Isobarik
  • Some audiophiles may not be able to see past the LP12

Comparisons (according to reviewers)

  • The 360 offers significantly improved imaging and soundstaging compared to the Klimax 350

Takeaway: The Linn 360 is a high-end loudspeaker that provides excellent sound quality and flexibility, making it a great choice for enjoying music with friends or for personal listening sessions. Its innovative design and technology deliver a detailed and immersive audio experience.

Magico
The Magico M7 is a four-way, six-driver floorstanding loudspeaker capable of astonishing performance. Featuring the latest Magico drive-unit technology, an organically shaped carbon-fiber-and-aluminum enclosure, and the latest Elliptical Symmetry Crossover, the M7 is a tour de force of advanced loudspeaker engineering. The M7 was conceived by Founder and CEO Alon Wolf as a more accessible version of the semi-active M9.
Check on Amazon
Magico is one of the leading American hifi brands, celebrated for its speakers' precision, clarity, and transparency. This reputation is built on the founder’s meticulous focus on eliminating vibrations, a design principle that customers claim significantly enhances sound quality. Their speakers incorporate carbon fiber and aluminum, along with custom-made drivers, to deliver a highly transparent listening experience. Magico’s sound is incredibly revealing, though some listeners may find it unforgiving with poorly recorded material. These speakers are favored by reviewers and audiophiles who prioritize transparency and accuracy above all else.
Expand Details

Our Summary

Product Strengths

  • The Magico M7 delivers the highest sound quality by the reviewer's metrics
  • Described as 'vivid' due to a comprehensive lack of distortion, low compression, rich texture and detail, and coherence across the spectrum and image
  • Soundstaging hangs in space with a realistically large soundstage window and deeper stage depth, approximating real sound in a real performance hall
  • Superb instrumental definition with a tonal density that removes a filter, revealing the believable richness of each instrument combined with high definition and low etch
  • Voicing is resolutely flat in terms of frequency response, so well-balanced recordings sound impressively right

Product Considerations

  • The M7 might require bigger amplifiers to reach the dynamic levels of the best horn speakers
  • It will not be a good fit for listeners who need frequency colorations to reassure them that their expensive speakers are doing something

Comparisons (according to reviewers)

  • Vs MBL 101X, the M7 does a more believable simulation of the stage because it's rather clear about performer locations, but the MBL-101X gets the image off the speakers more reliably, but at the price of some placement precision and air

Takeaway: The Magico M7 speakers deliver a rare and significant sonic achievement with a focus on distortion minimization. These speakers set a benchmark across almost all important sonic dimensions, making them worth considering for serious audio enthusiasts.
