Supra Classic 2.5 2X Speaker Cable - Custom Length

 

The Supra Classic 2×2.5 mm² speaker cable is a high-performance solution tailored for mid-powered systems and short-length high-powered Hi-Fi setups. It's also ideal for treble and bass wiring in bi-wired or bi-amped configurations. Part of Supra’s respected Classic Series, this cable uses flexible, tin-plated, multi-strand 5N oxygen-free copper, offering clean signal transmission and enhanced durability. The tin-plated copper conductors provide resistance to corrosion while reducing the skin effect, ensuring accurate signal flow and preserving musical detail.

The specially formulated PVC insulation not only protects the conductors but also improves over time, maintaining consistent audio quality throughout the cable’s lifespan. Perfect for audiophiles upgrading from basic speaker cables, the Supra Classic 2×2.5 mm² is a reliable choice for delivering balanced and transparent sound. A halogen-free, flame-retardant version (Classic/H FRHF) is also available, meeting strict safety requirements for professional and public audio installations. Engineered for clarity, signal integrity, and long-term stability, this cable is designed to meet the needs of serious audio enthusiasts looking for a dependable upgrade without unnecessary complexity.

 

Classic Series – The Original Standard in High-Performance Cabling

Supra’s Classic Series is built on years of expertise, featuring tin plating that enhances corrosion resistance while reducing the skin effect to ensure a clean, uninterrupted current flow. This prevents unwanted timing errors in the music signal, preserving clarity and accuracy. The high-quality PVC insulation is specially chosen for its chemical stability, which enhances the tin surface over time for consistent sonic quality. Available in a flame-retardant, halogen-free version (Classic/H FRHF), the Classic Series meets stringent safety standards, making it suitable for professional and public installations that demand both performance and safety. Supra Classic cables are the entry-level choice for audiophiles, offering a significant audio upgrade over standard Hi-Fi kit cables. Available in various sizes to meet diverse power demands, the Supra Classic 2×2.5 mm² delivers exceptional clarity, making it an excellent choice for those seeking quality and reliability in every note.

 

Elite Reference Series Plugs: Next-Level Audio Connectivity

The Elite Reference AirTite plugs offer significant advantages over traditional screw-based speaker cable plugs. Unlike screw designs, which may loosen over time and potentially impact the connection and sound quality, the Elite Reference plugs use a cold-weld method to create a secure and reliable bond between the cable and the plug. This helps maintain consistent performance and minimises signal loss, supporting clear and high-quality audio. With a ferrule-free design for direct signal transfer, beryllium copper cores, and 24K gold plating, they are engineered for enhanced conductivity and long-lasting durability. The addition of protective metal barrels further reinforces their professional-grade construction, making them an excellent choice for those who value dependable audio connections.

The Elite Reference plugs are engineered with additional advantages that make them stand out:

  1. AirTite Ferrule-Free Design - Unlike traditional plugs that use ferrules, the Elite Reference plugs opt for direct conductor-to-plug contact, removing any potential barriers to signal transfer. Featuring four different inlet sizes, these plugs are perfectly tailored to fit various cable gauges with a cold-weld, air-tight design, that eliminates soldering, reduces resistance, prevents oxidation, and enhances durability.
  2. Beryllium Copper Core with 24K Gold Plating - The banana plugs feature a beryllium copper core, known for its exceptional mechanical strength and conductivity. This material resists corrosion and retains its shape, maintaining a tight and reliable connection over time. The 24K gold plating ensures a smooth, high-quality signal path while adding durability for years of consistent performance.
  3. Dual Functionality - Designed as BFA and banana plug compatible the Elite Reference banana plugs provide greater versatility, making them suitable for a broader range of speaker terminals. This added functionality ensures compatibility with high-end Hi-Fi setups and equipment.
  4. Silver Core Spade Plugs with Metal Barrel Protection - The spade plugs in the Elite Reference Series incorporate a silver base plated with 24K gold, offering superior conductivity compared to many alternatives. Unlike other spade plugs, the Elite Reference spades also include a durable metal outer barrel, providing additional protection and a premium finish.
  5. The Elite Reference plugs are manufactured in Taiwan, a region renowned for its precision engineering and high-quality manufacturing standards. This ensures that every plug is built to exact specifications, offering exceptional consistency, reliability, and performance.

Frequently Asked Questions

Start by considering your amplifier and speakers. For short runs or compact systems, basic oxygen-free copper cables may suffice. But if you're after tighter bass, better detail or a wider soundstage, an upgrade to a higher-quality cable, like those from Chord Company, AudioQuest or Atlas, can make a noticeable difference. For personalised recommendations, speak to our consultants here.
Loading...
Yes. Bi-wire cables separate the signal paths for high and low frequencies, which can improve control and reduce interference in compatible speakers. Single-wire cables are suitable for most systems, but bi-wire setups can offer sonic gains if your speakers and amp support them. Alternatively, you can use single-wire cables with matching jumper cables on bi-wirable speakers.
Loading...
Higher-end cables often use better conductors, insulation materials, and terminations, which can reduce signal loss and interference. Whether it's worth the investment depends on your system's resolution and your listening environment. Our team can help you choose based on your priorities.
Loading...
Yes, cable length can influence performance. Longer runs can introduce resistance and signal loss, especially with thinner cables. Where possible, try to keep left and right channel lengths similar, and choose an appropriate gauge for the distance.
Loading...
Jumper cables replace the metal links between binding posts on bi-wireable speakers. Stock jumpers can limit performance, while high-quality alternatives preserve signal integrity and improve coherence across frequencies. When replacing your manufacturer supplied links, we recommend to use jumper cables of equal or better quality than your speaker cable.
Loading...
All cables matter, and your system will require good quality cables for all of it's connections, however, if you were looking for the cable which will make the biggest difference, then we would recommend looking at the power cables from your wall socket, to your distribution block and/or amplifier. More often than not, we hear from customers, manufacturers, and our own tests that higher quality power cables can have a significant impact of the quality of your system.
Loading...
This entirely depends on your current system and your expectations. You could have a decent pair of speakers which are not matched correctly with your amplifier, or vice versa. Similarly, you may want a new source of media to listen to. There are also options to upgrade other aspects of your system, such as the power, isolation or cabling to get the most out of your system before upgrading the traditional components. The best way to find out your own upgrade path is to contact our consultants and we would be happy to help you.
Loading...
In short, yes, although, this depends on the quality of the cable and your speakers/amplifier. High quality speaker cables tend to be manufactured with 4 key areas, their conductor, dielectric, shielding and geometry. Each of these areas can optimise signal retention from your amplifier to your speakers. Cheaper speaker cables can use lower quality conductors (tin-plated copper or even steel-clad copper), with basic dielectrics (PVC), no shielding and minimal strands with no geometry. More expensive speaker cables start to introduce higher quality conductors (Oxygen-free Copper, Ohno Continuous Cast Copper, Silver-plated Copper or even Pure Silver), better dielectrics (XLPE, PTFE, Teflon etc.), different amounts of shielding (foil, ofc-braid, carbon etc) and various geometries (solid-core, different twists, higher gauges etc.). There are diminishing returns to consider between your speaker cable and your system, as well as the potential of bottle-necks in your system if you use a lower...
