Ortofon Reference Blue RCA 1m

Presentation of the Ortofon Reference Blue RCA Analog Audio Cable

The Ortofon Reference Blue modulation cable is an analog audio cable designed to deliver detailed and dynamic sound reproduction across the entire audio spectrum. Manufactured in Japan by Ortofon, this RCA cable stands out for its meticulous design and use of quality materials. It is aimed at audiophiles and music lovers seeking optimal audio signal transmission between the various components of their hi-fi system.

Technical Specifications

The Reference Blue cable features a linear capacitance of 360 pF/m, which helps preserve the integrity of the audio signal by minimizing undesirable capacitive effects. This low capacitance ensures excellent frequency response, particularly in the high frequencies, for precise and detailed sound reproduction.

The central conductor of the cable is made of high-purity oxygen-free copper wire. This material offers optimal electrical conductivity and reduces signal loss, ensuring faithful transmission of audio information. The diameter of the conductor has been carefully studied to achieve stable characteristic impedance throughout the length of the cable.

The dielectric insulation of the Reference Blue cable is made of low-density polyethylene (LDPE). This material has excellent insulating properties and low permittivity, which helps reduce capacitive effects and dielectric losses. LDPE insulation also offers great mechanical stability and high resistance to environmental stresses.

To effectively protect the audio signal from electromagnetic interference (EMI) and radio frequency interference (RFI), the Reference Blue cable is equipped with a tinned copper braided shield. This shielding acts as a Faraday cage, creating a protective barrier around the conductors. The dense and regular braiding of the shield ensures optimal coverage and low electrical resistance for effective grounding of disturbances.

The RCA connectors used on the Reference Blue cable are straight type and feature a 24-carat gold-plated finish. This noble finish offers excellent electrical conductivity and high resistance to oxidation, ensuring reliable and durable contact with the RCA jacks of devices. The connectors are equipped with a robust cable clamp for optimal cable retention and reduced mechanical stress at the connection point.

Sound Performance

In terms of sound, the Ortofon Reference Blue cable stands out for its ability to reproduce the finest details of the recording with great precision. Clarity and transparency are present, allowing you to appreciate all the subtleties of the music.

The cable offers a wide and deep soundstage, with precise positioning of instruments and voices. Channel separation is excellent, providing a beautiful sense of space and airiness. The timbres are reproduced with great fidelity, preserving the harmonic richness of each instrument.

Transients are fast and incisive, demonstrating the cable’s high responsiveness. Note attacks are sharp and precise, without dragging or confusion. The Reference Blue cable also excels in dynamic reproduction, offering a beautiful sense of contrast between soft passages and more intense moments.

The low register is deep, well-defined, and perfectly controlled. The bass is firm and articulate, without any heaviness or dragging. The midrange is natural and transparent, with a beautiful presence of voices and instruments. The highs are detailed, airy, and free from any harshness or aggressiveness.

The Reference Blue cable demonstrates great neutrality, respecting the sound signature of the devices it connects. It does not color the sound and allows the intrinsic qualities of each element in the audio chain to fully express themselves. Its tonal balance is remarkable, without emphasizing or attenuating any part of the spectrum.
