• The Børresen T-series is crafted in Denmark, embodying the expertise gained from our O- and M-series. The T-series is the result of extensive research and innovation, delivering exceptional performance in a refined design. The Børresen T-series has been heavily inspired by the Børresen M-series using downscaled M-technologies.
  • InPol² Mk2 is the evolution of the already well-known InPol², a historical exponent of the second generation of InPoL® amplifiers. The InPol² Mk2 was born from the need to have more power on 4Ω (20% more) and, consequently, more BIAS current. We also wanted to improve the power supply of the power amp. Last but not least, we wanted to offer the possibility of directly connecting digital sources, thanks to the integration with our HiDac Mk2.
  • Headphone Amplifier and Preamplifier

    The Phonitor x is both an outstanding headphone amplifier and an excellent preamplifier that can be used to directly drive power amplifiers or active speakers. With the optional DA converter, it not only plays from analog sources, but also directly from digital sources. The Phonitor Matrix allows speaker-like listening via headphones. Thanks to VOLTAiR technology, it offers all this in the highest possible sound qualit
  • We are convinced that smart integration of functions yields higher audio quality. The MU2 combines a music streamer with a superb DAC and a reference quality analog pre amp. Its built-in DAC takes full advantage of the Grimm Audio low jitter clock and high performance FPGA processor. A relay based analog volume control enables the MU2 to become the true ‘hub’ of your hifi system for both digital and analog sources. Just like with its sister product, the ‘digital output’ MU1, a Roon Labs server is on board so no external computer is needed to enjoy perfect streaming.
  • Quadraspire HiFi racks are easy to build and easy to reconfigure to accommodate any changes in your components.

  • From day one, our idea has been to bring about what has been missing in our audio listening experience. What we found to be missing is exactly what we have incorporated into our designs. Over the years, we have realized that the evolution of a loudspeaker has been limited by the acoustic contributions of the enclosure in which it is contained. Rather than combat these unwanted sonics inherent to traditional boxed speaker designs, we have chosen to eliminate the problem entirely. While the open baffle speaker is not a new concept, today's technology, combined with advancements in design and materials, has allowed us to focus on what we believe is the true evolution of this design.
  • Immerse yourself in the world of high-fidelity audio with the VIABLUE X-60 T6S Power US, the power cable that redefines your listening experience. Crafted for audiophiles and tech enthusiasts alike, this pinnacle of power cable technology ensures that your audio systems perform at their peak. The VIABLUE X-60 is more than just a cable; it's a gateway to audio excellence.
  • VIABLUE™ NF-S6 AIR Silver RCA analog cable: Our reference audio cable for a First Class listening experience. Specifically designed for the transmission of analog signals, NF-S6 AIR cables provide a clear, natural and perfectly well rounded sound. All frequencies are rendered in great detail and true to the original. The unique structure of the NF-S6 AIR includes an Air Pipe System, which creates an air-filled space in the center of 12 conductors. These conductors form a perfect circle around an Air Pipe. This set-up allows for a complete separation of the conductors, which forms the basis of a complete and fast signal transmission true to the original.
  • VIABLUE™ SC-6 AIR Silver-Series speaker cables are our reference cables for a First Class listening experience. They treat you to a pure sound and crystal clear acoustic patterns, brilliant highs and powerful basses. A striking distinction of all frequencies creates a wide and open stage. 6 single conductors are assembled in a circular array around a main Air Pipe. They so separately transmit high, middle and low frequencies. Each of these conductors contains 6 single conductors, which are also arranged in a circular fashion around additional isolating Air Pipes.
  • The EXR offers a high-performance, cost-effective design that provides extensive system configuration flexibility and infinite modularity. The Patented EXR Audio Stand System is the most cost-effective, high-performance audio stand system developed by HRS (US Patent No.: 11,751,682).  This Patented design has a unique asymmetrical 4-leg vertical support system that increases frame stiffness and overall performance compared to traditional 3 or 4-leg designs.
  • Designed as a range to accommodate any size and weight of speaker – standmount plus stand, floorstander or subwoofer – the Seismic Podium breaks the acoustic connection between the floor and the speaker, preventing the passage of deleterious vibrations both to and from the speaker cabinets. For a detailed explanation of why this is an absolute necessity before any speaker can perform to its true potential, read ‘Earthquakes on hi-fi’.
  • The Ultra 6 V2 is the first Ultra product to use opposing technology pockets. Order the Ultra 6 V2 with an Ultra Base which provides an additional 20% to 25% in performance. Order without the Ultra Base if used in an ESS rack or with a Component Stand.
