Cryogenic treatment of all metal components of the loudspeaker results in a further significant improvement in conductivity – unleashing finest and most subtle musical details. When metal components undergo cryogenic processing, they are subjected to extreme cooling. In the wake of this process, the crystal structure of the metal contracts more and more. Alloying elements are pushed out of the grain structure of the metal, which now becomes very similar to a monocrystal. These structural changes in the metal have a profound effect on its audio properties, resulting in an increase of conductivity by 6-8%.
The Børresen membrane consists of a composite of two layers of very thin carbon on both sides of a 4 mm Nomex honeycomb core. This composite structure – like the one used in formula 1 type of racing cars – provides the ultimate combination of stiffness to weight ratio. The exceptionally low weight of only 5.5 grams allows a very high acceleration factor in the driver, resulting in both outstanding resolution and higher efficiency.

Børresen Z5
- Positioning: Top-end of the Z-series, offering high-end performance with conventional components.
- Description: Features a high-efficiency ribbon tweeter and a unique magnet system, delivering clarity and dynamics akin to the 0-series but at a more accessible price point.
Børresen 05
- Positioning: Flagship model of the 0-series, representing the pinnacle of Børresen's technology.
- Description: Equipped with an iron-free magnet system and a composite membrane, delivering exceptional sound purity and precision. Surpasses the Z5 in terms of technological sophistication.

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.

The cabinets are heavily braced, block milled, compressed wood structures, beautifully veneered in walnut and fitted with solid walnut inserts. They follow the best of Danish furniture design traditions paired with the stylish shapes that were initially created by the late Franco Serbelin from Sonos Faber. The tweeter section is vented to balance out the build-up of air pressure. The bass sections consist of tuned ports calibrated for musically relevant frequencies.

Our summary
Product Strengths
- Exquisitely built with walnut veneer and artisanal fit and finish
- Uses patented iron-free magnetic motor, which reduces inductance
- Produces full-thickness bass down to 50Hz, and good, well-controlled bass down still further
- Presents an extremely accurate rendition of music played, offering a fast, reactive and uncolored performance
- Connectivity options should be considered
Product Considerations
- Requires 50–100 hours of music replay for break-in, with gradual improvements over the next few hundred hours
- Poor recordings sound really poor because of its revealing nature
Comparisons (according to reviewers)
- Vs Magico Q1, Raidho D-1 and Alta Audio FRM-2M Celestas, the Børresen 01 Silver Supremes are superior in every way
Takeaway: The Børresen 01 Silver Supreme Edition speakers offer exceptional clarity and refinement and a superb soundstage, and they reveal the artistry of musicians. They provide an amazing musical experience.

Our take on the brand
Our Summary
Product Strengths
- Very high transparency, very neutral, very accurate sound elevates the reproduction of music
- Extraordinary leading edge response makes instruments, especially brass, sound lifelike
- The beryllium tweeter provides some of the best high-frequency response reviewers have heard
- Spatial aspects of recordings are delivered incredibly well, with imaging that is wide, spacious, and tall
- Solid construction uses birch wood bracing inside the cabinet and thick aluminum side plates for structural rigidity and dampening
Product Considerations
- The speakers are expensive, requiring a significant financial investment
- Low sensitivity rating of 85 dB potentially requires a high-powered amplifier for optimal performance
- While the bass response is clean and tight, some listeners may prefer to supplement with subwoofers for deeper bass extension, particularly for genres like electronica or organ music
- One reviewer found that the NAD M23 Class D amplifier pairing was a bit too transistory, too hard, not enough warmth—not enough soul
Comparisons (according to reviewers)
- Vs Klipsch Jubilee: The Jubilee offers greater scale, plays louder with greater ease, and has bigger bass and dynamics, excelling in larger rooms
- Vs PureAudioProject Due at 15: The PureAudioProject offers greater scale and energizes the room more completely, representing significantly better value for the money
- Vs Kharma Elegance dB7-S: The Kharma offers greater bass shove but a less neutral, 'flamboyant' sound profile compared to the more 'modest, measured' CE1TX
Takeaway: The TAD-CE1TX offers high accuracy and neutral sound that audiophiles who value imaging and clarity will enjoy. With its high resolution, this is a speaker that rewards you with a quality sound.

Our take on the brand
Our Summary
Product Strengths
- Exceptional transparency and insight reveal details in recordings that other speakers miss
- Vivid dynamics and an ability to communicate shifts in musical mood explicitly
- Impressive engineering and design, with a cabinet that minimizes unwanted sound and resonances
- A convincingly layered and precisely focused soundstage is produced, with cohesive drive unit dispersion
- Highly differentiated bass reproduction reveals structure, fine dynamic gradations, and delicate shadings
Product Considerations
- A top-class partnering system is demanded due to its high level of transparency, and it will not hide weaknesses in other components
- Placement can be sensitive, requiring careful positioning close to a wall
- Frequency response rises noticeably towards the highs, which can be too much of a good thing with poor recordings
- Deep bass extension is lacking compared to larger alternatives
- Sound is sensitive to placement and acoustics
Takeaway: The Discovery 3Zero is a transparent and revealing speaker that offers an electrostatic-like sound, freeing music from any earthly weight. When partnered well and carefully set up, it is capable of sounding magical and delivering a highly exciting acoustic discovery journey.
