Tellurium Q Ultra Black II Power Cable

Tellurium Q Ultra Black II Power Cable

The Tellurium Q Ultra Black II Power Cable is a premium high-end mains cable designed to complement the performance of sophisticated audio components, combining exceptional musical coherence, refined detail and the natural sonic character of Tellurium Q’s acclaimed Black Family.

Developed as the first Ultra Black power cable, it replaced the earlier Ultra Silver Power Cable with improved performance while retaining the smooth, organic and detailed presentation associated with the Ultra Black range.

Unlike conventional power cables, the Ultra Black II has been developed as part of Tellurium Q’s dedicated approach to high-performance audio cabling, where electrical characteristics, construction and mechanical behaviour are considered together.

Its performance has attracted international recognition, including a five-star review from The Ear, which reported improvements in musical realism, bass articulation, dynamic expression and listening involvement.

The Ultra Black Family Sonic Signature

The Ultra Black II Power Cable follows the distinctive sonic philosophy of the Tellurium Q Black Family.

This family is associated with a smooth, finely detailed and naturally coherent musical presentation, without excessive brightness or artificial emphasis.

The Ultra Black II aims to allow connected components to communicate musical information with greater clarity, expression and tonal refinement.

Its character makes it particularly attractive for revealing high-end systems where maintaining a natural tonal balance is essential.

From Ultra Silver Power to Ultra Black II

The history of this model is unusual within the Tellurium Q range.

According to the manufacturer, the Ultra Black II is actually the first Ultra Black power cable. It was given the Ultra Black II designation to maintain consistency with the naming of the other second-generation Ultra Black cables.

The new power cable replaced the original Ultra Silver Power Cable, offering improved performance with the sonic qualities associated with the Black Family.

This makes the Ultra Black II an important product within Tellurium Q’s power cable development, rather than simply a revised version of an earlier Ultra Black power cord.

Engineered for High-End Audio Performance

Tellurium Q approaches audio cable development with particular attention to the relationship between electrical and mechanical characteristics.

Rather than focusing exclusively on a single construction material, the company’s broader design philosophy considers conductor properties, cable geometry, dielectric behaviour and mechanical factors.

The exact internal construction of the Ultra Black II Power Cable is proprietary, and the manufacturer does not disclose all design parameters.

The purpose of the design is to provide a high-quality mains connection that supports the intended performance of compatible audio equipment.

While a power cable is not part of the low-level analogue signal path, the manufacturer and independent reviewers report audible differences when using the Ultra Black II in suitably matched systems.

Exceptional Detail with Natural Musicality

Greater Clarity Without Listening Fatigue

The Tellurium Q Ultra Black II Power Cable is intended for listeners who value fine detail, tonal naturalness and a coherent musical presentation.

In the five-star evaluation published by The Ear, the reviewer reported improvements in midrange realism, high-frequency openness and bass articulation.

These observations are consistent with the manufacturer’s description of the Ultra Black Family as smooth, naturally detailed and musically involving.

Rather than pursuing exaggerated high-frequency energy, the cable’s intended character is one of refinement and balance.

Sound Quality and Listening Impressions

Bass Definition and Rhythmic Precision

One of the most notable observations in The Ear’s review was a perceived improvement in low-frequency speed and articulation.

The reviewer described a stronger sense of bass impact and improved rhythmic involvement when the Ultra Black II replaced the existing mains cable.

These listening impressions suggest that the Ultra Black II may be worth evaluating in systems where bass definition and musical drive are important priorities.

Midrange Realism and Instrumental Texture

Midrange reproduction plays an important role in the perception of natural sound.

The Ear reported additional realism in voices and instruments when using the Ultra Black II with the reviewer’s amplification.

For listeners who value expressive vocals, acoustic instruments and tonal richness, these findings make the cable an interesting option to audition.

High-Frequency Air and Openness

The review also described an increased sense of air and lightness in the higher frequencies.

Importantly, the Black Family sound philosophy focuses on preserving detail without introducing excessive harshness.

The Ultra Black II therefore aims to combine openness with a relaxed, naturally balanced presentation.

Dynamics and Musical Involvement

The reviewer’s experience with rock recordings was particularly enthusiastic.

Without changing the amplifier’s volume setting, the perceived intensity and physical impact of the musical performance increased.

This was described as a more immersive listening experience, with additional energy and involvement.

As with all reported sonic differences between mains cables, the result should be assessed in the context of the complete audio system.

Designed for High-End Audio Components

The Ultra Black II Power Cable can be considered for compatible audio equipment that uses a suitable detachable IEC mains connection.

Potential applications include:

• High-performance integrated amplifiers
• Compatible stereo power amplifiers
• High-end DACs and digital source components
• Reference CD players and transports
• Network music streamers and servers
• Balanced analogue preamplifiers
• Compatible phono stages

Before ordering, confirm the mains plug standard, equipment-side IEC connector, voltage and current requirements of the connected component.

The cable should only be used with an appropriate protective earth arrangement and compatible mains equipment.

Premium Construction and Connector Quality

Attention to Every Connection

The Ultra Black II features a distinctive black braided exterior, clearly printed cable identification and substantial mains connectors.

The design includes carefully finished cable entry points and secure mechanical strain relief.

The connector arrangement is selected according to the relevant mains standard and equipment requirements.

A secure, correctly rated connection is essential for both reliable operation and electrical safety.

Schuko, UK and US Plug Options

Tellurium Q lists the Ultra Black II Power Cable with regional mains plug options, including Schuko for continental Europe, UK and US configurations.

The equipment-side connector and cable configuration should be selected to match the intended audio component and the electrical requirements of the installation.

For customers outside Greece, Chameleon Audio can assist with identifying the appropriate configuration before ordering.

Never modify a mains plug, defeat the protective earth or use an unsuitable adaptor to make an incompatible cable fit.

Black Braided Cable Construction

Purposeful Design and Finishing

The Ultra Black II combines a distinctive black outer sleeve with the manufacturer’s recognisable cable identification.

The braided exterior and connector finishing contribute to a robust and carefully presented product.

When installing a high-performance mains cable, allow sufficient clearance behind the equipment and avoid excessive bending or tension.

Careful cable routing also helps prevent mechanical stress on the power inlet.
