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.

Qln's Signature communicates music's message with the utmost skill and balance. To achieve this, we took a deep look into every aspect of the speaker and interpreted them in relation to how we as humans hear and react to music. The Signature is the greatest expression of our core philosophy and approach to loudspeaker design.
Qln's Signature communicates music's message with the utmost skill and balance. How do we achieve this? Perfectly flat frequency response, low distortion, hyper detail, sparkling resolution? No! It doesn't matter how impressive a speaker measures if it leaves the listener un-involved with the music. It is this engagement that we at Qln passionately pursue in our designs.

To achieve this, we took a deep look into every aspect of the speaker and interpreted them in relation to how we as humans hear and react to music. A flat frequency response or low distortion doesn't say much about how a speaker ultimately sounds. There is so much more to this craft than is readily known or discussed. We have concentrated our efforts in perfecting a technically sound design that also evokes great emotion and sensory connection to music.

The Signature is the greatest expression of our core philosophy and approach to loudspeaker design. The Signature has always been a standalone model in Qln's portfolio. With the Signature the goal has always been to push the boundaries of what is possible for a monitor speaker with our truncated pyramid cabinet design. Each successive generation has taken a step in this direction and none more significant then now.

The Signature has always been at the forefront of technology with time aligned drivers, minimum baffle surface area, minimal cabinet resonance, ph...

Reviews

The critically acclaimed TAD-CE1 speaker system was known for its innovative design inside and out to reproduce musical sounds down to the last detail of the original—without adding or subtracting anything that might alter the subtleties and nuances intended by recording artists and producers. We have taken the already impressive performance of the CE1 to the next level when designing the new TAD-CE1TX—by incorporating refinements and innovations inside and out. The TAD-CE1TX gives a whole new meaning to the two-channel reproduction of music. The CE1TX combines the pinpoint localization of sound images with three-dimension-like sound-field reproduction between the right- and left-channel speakers to create a “being-there” experience for a listener. You would feel as if you were in a recording studio, listening to musicians play their parts. The CE1TX has exquisitely honed its quality to provide an immersive sound-field experience to you.

Technical Audio Devices is a hifi Japanese spinoff of Pioneer that focuses on highly accurate speakers, which reviewers widely regard as best-in-class. They're known for their unique vapor deposition technique for beryllium diaphragms, which provides superior strength and smooth performance up to 100 kHz. Their proprietary technologies include CST (Coherent Source Transducer) for controlled directivity from a single point.

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.

We began with the launch of the highly acclaimed and award-winning 0-series loudspeakers. Willing to break new ground, we designed innovative electronic components, used unconventional materials and employed state-of-the-art manufacturing processes. Since all of these audio components are engineered and assembled in-house, highest quality standards are permanently ensured.

The Børresen tweeter has exceptional efficiency. Elaborate finite element methods have been applied to linearize and optimize the magnetic flux field, to facilitate driver movement and to ensure high efficiency and outstanding linearity. The efficiency of this closed ribbon tweeter amounts to an exceptional 94dB and operates from approximately 2.5 kHz upwards. The moving mass is extremely low at 0.01 grams. The totally concealed tweeter has the capacity to operate at an incredible speed, which is an absolute prerequisite to unlocking the most subtle and refined sound details of any kind of music.

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 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.

The Børresen magnet system is breaking new ground with its unique, innovative design. It uses 4 opposing neodymium ring-magnets and solid copper discs as pole pieces, eliminating iron and its associated distortion issues. This system provides faster driver response, refined detail, and authentic bass performance.

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. 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.

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.

  • Capable of producing deep and accurate bass, especially given its size
  • Offers a very accurate rendition of music—completely uncolored and offering ultimate refinement
  • Retrieves a high level of detail, harmonic separation, and immediacy due to fast and efficient drivers
  • Speaker terminals will only accept banana/BFA-styled cable terminations

Product Considerations

  • Has limited low-frequency extension given it is a stand-mounted monitor
  • Requires careful system matching to ensure optimal performance
  • Poor recordings will sound really poor due to the speaker's revealing nature

Comparisons (according to reviewers)

  • Vs Franco Serblin Accordo Essence: Børresen has the upper hand on resolution and transparency

Takeaway: The Børresen 01 offers a high-fidelity experience by communicating musical nuances, capturing a live experience. These speakers excel in presenting the artist's intent, bringing listeners closer to the original performance.

Reviews

The third generation of a Wilson Benesch classic. The original ‘Discovery’ name was a reference to the development of the unique acoustic presentation that the first Discovery loudspeaker delivered when it was launched in 2002. A 2.5-way standmount monitor like no other, the Discovery 3Zero deploys the same unique drive topology as the original classic, placing the Fibonacci Tweeter and a dedicated Tactic 3.0 midrange drive unit in close proximity to the powerful Isobaric Drive System that sits directly on the underside of the loudspeaker in the vertical plane. With all drive technologies placed within a few inches of one another, time alignment and integration across the Discovery 3Zero frequency band is unmatched. The Discovery 3Zero delivers a lightning-fast, punchy, highly accurate and endlessly captivating presentation.

Wilson Benesch pioneered the use of carbon fiber in audio products, starting with their 1991 turntable, and continues to use this material extensively in their loudspeakers for its unique structural advantages. Their speakers feature an isobaric driver configuration that enables deeper bass from smaller cabinets, and they manufacture almost all components in-house, including their distinctive curved monocoque enclosures that reduce resonance.
