Why This Guide Matters
If you're connecting a turntable, amplifier, TV, or laptop to a hi-fi system, you don't need to spend a fortune on RCA (phono) cables to get clean, reliable analogue audio. In fact, one of the biggest myths in home audio is that expensive cables sound better. They don't. What actually matters is decent shielding to keep hum and interference out, solid gold-plated connectors that won't corrode, and choosing the correct length and cable type for your setup. This guide covers six genuinely useful budget RCA cables from Kenable, all priced under £8, so you can pick the right one for your gear without overpaying.
Factors to Consider When Buying RCA Cables
- Shielding: A shielded, oxygen-free copper (OFC) core reduces hum and interference, especially important for turntables and long cable runs near mains wiring.
- Connector type: Twin RCA plug-to-plug leads connect two devices with RCA sockets directly. Plug-to-socket versions extend an existing cable. 3.5mm-to-RCA leads are for connecting phones, laptops or a TV's headphone output to an amplifier.
- Plug quality: Gold-plated connectors resist corrosion and give a more reliable, lower-resistance contact than uncoated plugs — worth having even on a budget cable.
- Length: Buy the shortest cable that comfortably reaches between your devices. Excess length can pick up more interference and clutters your setup.
- Turntable extras: If you're wiring a turntable, look for a cable with an earth/ground tag wire to eliminate hum from the phono stage.
- Tangle resistance: For longer runs across a room, a tangle-free jacket makes installation and cable management much easier.
Spend your money on good shielding and the correct length, not on exotic cable materials or premium branding. A well-made £2 OFC cable will perform identically to a £50 "audiophile" cable for standard home audio use.

Installation and Setup Tips
- Always match red-to-red and white-to-white (or red-to-red, black-to-black) between source and receiver to keep left and right channels correct.
- If using the turntable cable with a ground tag wire, connect it to the amplifier's chassis earth terminal — this alone fixes most turntable hum issues.
- Keep RCA cables away from mains power cables where possible; running them parallel and close together for long distances increases the chance of hum.
- Push plugs in fully. A loose connection is one of the most common causes of crackling or intermittent sound.
- When using an extension cable, minimise the number of joins in the signal path — one extension is fine, but stacking several will degrade shielding effectiveness.
Don't coil excess cable tightly next to power supplies, routers, or mains transformers — this is a common source of hum and buzz that has nothing to do with cable quality.
Common Mistakes to Avoid
- Overspending on "audiophile" cables: For standard analogue connections at home, a well-shielded OFC cable with gold plugs performs the same as far pricier options. Extra money is better spent on speakers or a good amplifier.
- Buying the wrong connector type: Check whether you need plug-to-plug (for two devices with RCA sockets) or plug-to-socket (an extension), and whether a 3.5mm-to-RCA adapter cable is needed for a phone, laptop, or TV.
- Ignoring turntable earthing: Skipping the ground tag wire on a turntable connection is one of the most common causes of persistent hum.
- Choosing the wrong length: Too short and it won't reach; too long and you'll have excess cable to manage and a slightly higher chance of interference.
- Forgetting channel colours: Mixing up red and white connections swaps your left and right channels.
Frequently Asked Questions
Do expensive RCA cables really sound better than budget ones?
No, not for standard home audio use. Once a cable has adequate shielding, oxygen-free copper conductors, and solid gold-plated connectors, further spending doesn't improve sound quality in any way you can hear. Focus your budget on correct length and good shielding rather than premium branding.
What's the difference between plug-to-plug and plug-to-socket RCA cables?
A plug-to-plug cable, like the Pure OFC HQ or Pro Audio Metal leads, connects two devices directly. A plug-to-socket cable, such as the RCA Phono Twin Plugs to Sockets Extension, is designed to extend an existing cable rather than connect two devices on its own.
Which RCA cable should I use for a turntable?
Choose a shielded cable with an earth/ground tag wire, such as the Twin RCA Shielded Phono Audio Cable with OFC and tag wire. Connecting the tag wire to your amplifier's earth terminal removes most hum issues common with phono connections.
How do I connect my phone or laptop to a hi-fi amplifier?
Use a 3.5mm stereo jack to twin RCA cable, such as the 5m version listed above, plugging the 3.5mm end into your phone, laptop, or TV's headphone/audio-out socket and the RCA ends into your amplifier's input.
