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.

The Børresen 03 Silver Supreme Edition speaker is equipped with enormous driver power and dynamics. The speaker resolves even the most fragile details from any audio source. The driving power in the lower bass segment, along with an easygoing punch, provide a unique sound stage liveliness.
The Silver Supreme Edition loudspeakers are the absolute flagship versions among the Børresen loudspeakers. By replacing the copper pole rings by in-house manufactured, hand-crafted silver rings the inductance is reduced substantially. Additionally, all metal components, are subjected to a cryogenic treatment. These loudspeakers set a new and unsurpassed benchmark. Clarity, refinement and sound staging at its very best.

The patented Børresen iron-free magnetic system has been further refined. Børresen uses iron-free drivers in all its loudspeakers. Their inductance is about ten times lower than that of conventional drivers. This exceptionally low inductance has now been even further reduced to an unprecedented new minimum level – about 12 times lower than the inductance level of conventional, iron-based drivers.

Since silver has 6-8% better conductivity than copper, we replaced the copper pole rings with in-house manufactured, handcrafted silver rings. To take full advantage of all the performance-enhancing audio properties of the Silver Supreme 0-series, all other metal components of these premium speakers also undergo cryogenic treatment. This reduces their inductance by another 6-8%. The result is absolute musical purity.

The cabinets are heavily braced, block milled, compressed wood structures, beautifully veneered in walnut and fitted with solid walnut inserts. They fol...

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.

Our Summary

Product Strengths

  • Tidy, Scandinavian look with a clean design
  • The Børresen 05s go down to 25 hertz and are 90 dB efficient
  • The Børresen 05s throw a holographic soundstage
  • The 05 SSEs flood the room with perfectly proportioned low-frequency energy and compensate for room-related frequency dips naturally
  • The 05 SSE is capable to display a large, precise and three-dimensional sonic image

Product Considerations

  • The 05 SSEs need to be focused on the listening position
  • The speaker cables of 05 SSE need time to accumulate hours of operation

Comparisons (according to reviewers)

  • Vs Göbel High End Aeon—the 05 SSEs definitely stand up to these in terms of transient reproduction and speed

Takeaway: The Børresen 05 loudspeakers offer a clean, Scandinavian design and produce a holographic soundstage that immerses the listener in the music. With their ability to deliver a realistic and engaging listening experience, they are worth considering if one is seeking high-end audio performance.

Wilson Audio
Alexx V
154000
/
Released
2021
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 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.
