That’s right – you read the title correctly! We’re dedicating an entire article to the best RCA cables. And where would we be without them, eh? Our hi-fi setups would be as useless as a sports car without wheels.
They might not be the flashiest piece of gear, but a quality set of audio interconnects ensures your sound stays clean, clear, and free from interference. Whether you’re after a solid budget-friendly option or an audiophile-grade cable that extracts every last detail from your music, we’ve got you covered.
We’ll also cut through the noise and break down what makes a difference. If you’re looking for an easy upgrade without overhauling your entire setup, swapping out your RCA cables is a great place to start. The right interconnects can reveal hidden details in your music, reduce unwanted noise, and help your gear perform at its absolute best.
Why invest in a good RCA cable?
Let’s be honest, RCA cables all serve the same basic purpose: transmitting analogue audio between components. There’s no secret fairy dust that makes buying an RCA cable twice the price of your amplifier worth it. Your speakers, amp, and separates will always impact sound the most.
So, why bother investing in a quality RCA cable?
The short answer: signal integrity. Hi-fi systems are designed to capture and reproduce detailed sound, but if you’re using cheap interconnects with poor shielding, electrical noise and radio interference can leak in.
Your system doesn’t distinguish that interference from the audio signal, so it manifests as hum, hiss, or distortion – ultimately compromising your sound quality. The fix? A well-built RCA cable.
In theory, the more you spend on interconnects, the less interference you’ll experience. That’s true – but at what point do the improvements become so small that they’re barely noticeable?
Spending a little extra on a well-shielded cable with quality connectors is a smart investment, but beyond a certain price, differences become increasingly subjective. Not non-existent – some listeners swear by high-end cables – but some struggle to hear any change at all. Invest wisely and don’t let cable choice become the main obsession. At the end of the day, your music should be the priority.

How to choose the best audio cables for you
When choosing RCA cables, it’s important to consider your budget, system, and brand reputation. A well-matched cable can enhance your setup, but spending excessively won’t always yield noticeable improvements. Brands like QED, AudioQuest, and Chord Company are entirely devoted to developing high-quality cables designed to minimise signal loss.
These brands invest in better materials, shielding techniques, and specialised engineering processes. However, not every setup will benefit from high-end cables, so it’s important to match your cable choice to your equipment’s level.
So what does paying a little extra for cables get you?
Budget options often use cheaper materials like aluminium or copper-clad aluminium (CCA), which are less conductive and more prone to signal loss. These may work for basic setups but can introduce interference or degrade over time. A good standard for hi-fi is oxygen-free copper (OFC) or silver-plated copper.
But this doesn’t mean you have to spend a fortune. Many affordable audio cables use OFC, offering better conductivity and durability than lower-grade materials. OFC minimises impurities, reducing resistance and ensuring cleaner signal transmission. Silver-plated copper takes this a step further by improving high-frequency performance and detail retrieval, though the benefits are most noticeable in revealing hi-fi systems.
Spending more can also get you better shielding and connector quality. Gold-plated RCA connectors resist corrosion and improve signal stability, while high-density shielding minimises electrical interference for a cleaner sound.
Premium cables may also feature advanced conductor designs, like twisted-pair or multi-core geometries, which enhance signal integrity by reducing capacitance and crosstalk, ensuring accurate transmission of audio frequencies with minimal phase shift where different frequencies arrive at slightly different times – preserving accurate timing, stereo imaging, and the clarity of transients for a more natural sound.
If you’re setting up a full hi-fi or home cinema system, consider custom cable bundles. Hand-crafted cable terminations allow you to choose the exact length and connectors needed, ensuring a precise fit without excess cable or undue stress on connections.
How much to spend on an RCA cable
Simply put, how much you spend on cables should be proportional to your system’s total cost. A good rule of thumb is to allocate 10–15% of your budget to interconnects.
For example, if you buy a £500 hi-fi bundle, a good match would be RCA and speaker cables in the £50–£75 range. Likewise, a £2,000 setup would benefit from cables around £200 to maintain clean signal transmission.
The most notable improvements tend to come when upgrading from budget to mid-range cables, while the difference between mid-range and ultra-premium options is often more subtle. That said, if you’re investing £10,000+ in a high-end system, premium cables just make sense.
You also have to consider your system layout, as cable prices can vary dramatically depending on length – just be aware. You could consider acoustic treatment or isolation equipment before upgrading to super-expensive models.
FAQs
What cable gives you the best sound quality?
The cable that gives you the best sound quality depends on your system’s connectivity. XLR cables offer superior noise rejection for professional audio, HDMI transmits high-resolution digital audio and video, and RCA is ideal for analogue connections. The best cable for you is relative.
Are gold RCA cables better?
Gold RCA cables are better in terms of corrosion resistance and durability. Gold-plated connectors prevent oxidation, ensuring a longer lifespan and consistent signal quality. However, gold does not improve sound transmission itself; the overall construction, shielding, and conductors matter more.
Are RCA cables obsolete?
RCA cables aren’t obsolete but are becoming less common in modern audio and video systems. Certainly, in TV and home entertainment, component RCA cables have been replaced by HDMI for higher-resolution transmission. However, in hi-fi, RCA remains essential for equipment like CDs and turntables.
Final thoughts
Audio interconnects might not be the most exciting part of a hi-fi setup, but they play a crucial role in keeping your audio clean and interference-free.
A good RCA cable will minimise noise and provide a stable connection, but the best RCA cables go further, offering better shielding, higher-quality conductors, and more secure connectors to ensure maximum signal clarity. While you don’t need to spend a fortune, investing in a well-matched cable for your system can help you get the most out of your setup.
If you’re currently refining your system, it’s worth looking at the best speaker cables and understanding HDMI cables to make sure every part of your setup is optimised. Speaker cables are just as important as RCA interconnects for maintaining signal clarity, while HDMI is essential for high-resolution digital connections in home cinema and AV systems.
And if you’re new to hi-fi or setting up a system for the first time, our guide to connecting your CD player to an amplifier walks you through using RCA cables properly, along with other possible connections like optical and balanced XLR.
