Collection: RCA Cables

An RCA cable transmits analogue audio signals unbalanced between two HiFi devices – typically from the source to the amplifier.

Why a good RCA cable?

RCA is the unbalanced line connection you'll find on almost every device: streamers, DACs, CD players or phono stages connect to the amplifier this way. Because the signal here is still small and sensitive, good shielding and clean connectors matter. A decent RCA cable keeps interference out and sits firmly – so the cheapest cable of all doesn't end up as the bottleneck between source and amplifier.

What matters

Pay attention to effective shielding, firmly seated connectors and a length that suits your setup. At HD Zürisee in Wädenswil we help you choose the right RCA cable for your source and amplifier, and terminate line cables to custom length on request. What matters is that the cable matches the signal level – a phono or subwoofer signal has different requirements than a normal line output.

Who it's for – and straight talk

For anyone connecting source and amplifier in analogue: from an entry-level setup with a single streamer to a chain with separate pre-amp and power amp. Even when switching to a new device, it's worth taking a look at the cable you've been dragging along for years.

Straight talk: a well-shielded RCA cable with solid connectors reliably does its job. The biggest difference you'll hear is when you replace a genuinely bad cable – not when you jump from good to very expensive. We tell you when an upgrade is worthwhile and when it stays cosmetic.

Verdict: good shielding, firm fit, matching length – then the RCA cable causes no trouble. If your devices have XLR and you need longer runs, ask us about the balanced alternative.

Frequently asked questions

What's the difference between RCA and XLR?

RCA transmits unbalanced and is the widespread standard on almost every device. XLR transmits balanced and is quieter over long runs and in electrically noisy environments. For typical distances, RCA does its job flawlessly; for long runs with XLR-capable devices, XLR is worthwhile.

How long can an RCA cable be?

For normal setups, one to three metres is unproblematic. The longer the run and the noisier the environment, the more important good shielding becomes, and possibly a balanced XLR connection. Tell us the length you need, and we'll find the right solution.

Do I need expensive RCA cables?

Not necessarily. From a solid level with good shielding and firm connectors, the basic need is covered. Higher-resolution chains benefit more finely, but the biggest gain in sound is replacing a genuinely bad cable. We advise you based on your system, not the price tag.

Can I also use an RCA cable for a subwoofer or phono?

For the subwoofer there are special, often single-core cables with matching shielding; we have a dedicated category for that. Phono has particular requirements due to the tiny signal and usually needs a dedicated phono cable. If in doubt, ask us and we'll assign it correctly.

Do you terminate line cables to custom length?

Yes, we make line cables to the length you want with matching RCA connectors. That way you get exactly the length your setup needs, cleanly finished and without unnecessary excess between devices.

Why buy RCA cables at HD Zürisee?

Because we recommend the cable that matches source, amplifier and signal level – instead of simply the most expensive. We know the differences between line, phono and subwoofer signals and terminate to custom length on request. We advise you personally and deliver throughout Switzerland – free shipping from CHF 190.
