Congratulations\u2026 welcome to the audiophile rabbit hole! At its core, the pursuit of great sound often comes down to one thing: a clean signal. And sometimes, the culprit behind unwanted noise is your cable.<\/p>\n<p>Strip away the fancy branding and you&#8217;re left with metal wire, perfect for picking up interference from things like power leads, routers, and appliances. Some cables include shielding to help block this, but the real fix lies in how the cable handles the signal.<\/p>\n<p><strong>Unbalanced cables<\/strong>, like <a href=\"https:\/\/www.av.com\/stereo-phono-rca-cables\" target=\"_blank\" rel=\"noopener\"><strong>RCA<\/strong><\/a> and <a href=\"https:\/\/www.av.com\/aux-cables\" target=\"_blank\" rel=\"noopener\"><strong>3.5mm AUX cables<\/strong><\/a>, use two internal wires: one for audio, one for ground. They&#8217;re common in home setups and fine for short runs, but they&#8217;re prone to picking up hum.<\/p>\n<p><strong>Balanced cables, <\/strong>like <a href=\"https:\/\/www.av.com\/xlr-din-cables\" target=\"_blank\" rel=\"noopener\"><strong>XLR<\/strong><\/a>, are built to fix that. They use three wires: one ground, and two signals &#8211; one inverted. When the signal reaches the other end, the inverted one is flipped back, cancelling out any noise.<\/p>\n<p>This is why balanced cables are the go-to in studios and high-end rigs. In everyday hi-fi, unbalanced cables are just fine. But if you&#8217;re chasing the cleanest sound possible, balanced are worth a look.<\/p>\n<p>[\/et_pb_text][et_pb_text admin_label=&#8221;Audio cable types explained 1.

Thicker cables (lower AWG numbers) carry power more efficiently, especially over longer distances. Most home audio systems use oxygen-free copper (OFC) or long grain copper &#8211; both offer reliable signal transfer and long-term performance.<\/p>\n<p>For general use, OFC cable like the <a href=\"https:\/\/www.av.com\/Cables\/Fisual-S-Flex-Studio-Grade-White-Speaker-Cable-2-x-15mm-100m-Reel\/4CV5\" target=\"_blank\" rel=\"noopener\"><strong>Fisual S-Flex<\/strong><\/a> will be just fine. If you\u2019re running longer distances or powering demanding speakers, opt for 14 or 12 AWG for better results.<\/p>\n<p>For an upgrade, try something like the <strong><a class=\"ProsemirrorEditor-link\" href=\"https:\/\/www.av.com\/Cables\/QED-Reference-XT40i-Customisable-Speaker-Cable\/4GJV\" target=\"_blank\" rel=\"noopener\">QED Reference XT40i<\/a><\/strong> or <a href=\"https:\/\/www.av.com\/Cables\/Chord-Company-RumourX-Speaker-Cable\/4RSQ\" target=\"_blank\" rel=\"noopener\"><strong>Chord RumourX<\/strong><\/a> &#8211; both are designed to reduce distortion and enhance detail through premium copper construction. If you need more options, our list of <strong><a href=\"https:\/\/www.av.com\/blog\/best-speaker-cables\/\" target=\"_blank\" rel=\"noopener\">favourite speaker cables<\/a><\/strong> gives you six to choose from.<\/p>\n<p>Once you\u2019ve chosen your cable type, the next step is picking the right layout for your setup. Most speaker cables are 2-core, meaning one side carries the positive signal, the other the negative. This is standard for the majority of home systems and works perfectly well in most cases.<\/p>\n<p>Some amps and speakers support <a href=\"https:\/\/www.av.com\/speaker-cables?page=1&amp;filters[2016]=13020#cbls\" target=\"_blank\" rel=\"noopener\"><strong>bi-wiring<\/strong><\/a>, which uses 4-core to separate the treble and bass signals. This can offer subtle improvements in clarity and stereo separation by giving each frequency range its own path. That said, it\u2019s not essential. Most bi-wireable speakers include metal bridging plates between terminals, so 2-core cable remains a reliable choice.<\/p>\n<p>If you\u2019re routing cable through walls or ceilings, choose one that meets safety standards like the <a href=\"https:\/\/www.av.com\/Cables\/QED-QX16-2-Flame-Retardant-PVC-Speaker-Cable-White\/4AYA\" target=\"_blank\" rel=\"noopener\"><strong>QED QX16\/2<\/strong><\/a>, which features a flame-retardant, in-wall-rated jacket.<\/p>\n<p>We\u2019ve had to keep it brief here, but for more details, including what plug to use, check out our full <a href=\"https:\/\/www.av.com\/blog\/how-to-wire-speakers\/\" target=\"_blank\" rel=\"noopener\"><strong>guide to wiring speakers<\/strong><\/a>.<\/p>\n<p>[\/et_pb_text][et_pb_button button_url=&#8221;https:\/\/www.av.com\/speaker-cables#cbls&#8221; url_new_window=&#8221;on&#8221; button_text=&#8221;FIND OUT MORE&#8221; button_alignment=&#8221;center&#8221; _builder_version=&#8221;4.18.0&#8243; _module_preset=&#8221;default&#8221; custom_button=&#8221;on&#8221; button_text_size=&#8221;14px&#8221; button_text_color=&#8221;#FFFFFF&#8221; button_bg_color=&#8221;#0e95cf&#8221; button_border_width=&#8221;0px&#8221; button_border_color=&#8221;#0e95cf&#8221; button_font=&#8221;Arial|700|||||||&#8221; button_icon=&#8221;&#x35;||divi||400&#8243; button_icon_color=&#8221;#FFFFFF&#8221; custom_padding=&#8221;10px|30px|10px|30px|false|false&#8221; box_shadow_style=&#8221;preset6&#8243; box_shadow_blur=&#8221;2px&#8221; global_colors_info=&#8221;{}&#8221;][\/et_pb_button][et_pb_text admin_label=&#8221;2.

Because they\u2019re unbalanced, though, RCA cables are more prone to picking up interference, especially over longer runs. That\u2019s why it\u2019s best to keep them fairly short.<\/p>\n<p>Look for RCA cables with good shielding and snug-fitting connectors. A well-made cable will reduce the risk of hum and ensure a solid, consistent connection without needing to jump up to XLR-level kit. The <strong><a href=\"https:\/\/www.av.com\/Cables\/Chord-C-line-Stereo-RCA-Cable-1m\/4P8H\" target=\"_blank\" rel=\"noopener\">Chord C-line<\/a><\/strong> is a great all-round option, nicely made and a good match for most mid-range hi-fi setups.<\/p>\n<p>RCA cables also come in a variety of adapter formats, depending on what you\u2019re connecting. One common type is <a href=\"https:\/\/www.av.com\/stereo-phono-rca-cables?page=1&amp;filters[2133]=21596\" target=\"_blank\" rel=\"noopener\"><strong>RCA to 3.5mm<\/strong><\/a>, like the <strong><a href=\"https:\/\/www.av.com\/Cables\/QED-Connect-35mm-Jack-Phono-15m\/4MMR\" target=\"_blank\" rel=\"noopener\">QED Connect 3.5mm to RCA cable<\/a><\/strong>, which is perfect for linking hi-fi gear to portable devices, desktop DACs, or anything with a headphone-style mini-jack output.<\/p>\n<p>At the other end of the spectrum, you might come across <a href=\"https:\/\/www.av.com\/stereo-phono-rca-cables?page=1&amp;filters[2133]=21597\" target=\"_blank\" rel=\"noopener\"><strong>RCA to XLR<\/strong><\/a>, such as the <strong><a href=\"https:\/\/www.av.com\/Cables\/Chord-ClearwayX-2XLR-to-2RCA-Cable-1m\/4QHD\" target=\"_blank\" rel=\"noopener\">Chord ClearwayX RCA to XLR cable<\/a><\/strong>.

Congratulations\u2026 welcome to the audiophile rabbit hole! At its core, the pursuit of great sound often comes down to one thing: a clean signal. And sometimes, the culprit behind unwanted noise is your cable.<\/p><p>Strip away the fancy branding and you're left with metal wire, perfect for picking up interference from things like power leads, routers, and appliances. Some cables include shielding to help block this, but the real fix lies in how the cable handles the signal.<\/p><p><strong>Unbalanced cables<\/strong>, like <a href=\"https:\/\/www.av.com\/stereo-phono-rca-cables\" target=\"_blank\" rel=\"noopener\"><strong>RCA<\/strong><\/a> and <a href=\"https:\/\/www.av.com\/aux-cables\" target=\"_blank\" rel=\"noopener\"><strong>3.5mm AUX cables<\/strong><\/a>, use two internal wires: one for audio, one for ground. They're common in home setups and fine for short runs, but they're prone to picking up hum.<\/p><p><strong>Balanced cables, <\/strong>like <a href=\"https:\/\/www.av.com\/xlr-din-cables\" target=\"_blank\" rel=\"noopener\"><strong>XLR<\/strong><\/a>, are built to fix that. They use three wires: one ground, and two signals - one inverted. When the signal reaches the other end, the inverted one is flipped back, cancelling out any noise.<\/p><p>This is why balanced cables are the go-to in studios and high-end rigs. In everyday hi-fi, unbalanced cables are just fine. But if you're chasing the cleanest sound possible, balanced are worth a look.<\/p><hr \/><h3>Audio cable types explained<\/h3><h4>1.

Thicker cables (lower AWG numbers) carry power more efficiently, especially over longer distances. Most home audio systems use oxygen-free copper (OFC) or long grain copper - both offer reliable signal transfer and long-term performance.<\/p><p>For general use, OFC cable like the <a href=\"https:\/\/www.av.com\/Cables\/Fisual-S-Flex-Studio-Grade-White-Speaker-Cable-2-x-15mm-100m-Reel\/4CV5\" target=\"_blank\" rel=\"noopener\"><strong>Fisual S-Flex<\/strong><\/a> will be just fine. If you\u2019re running longer distances or powering demanding speakers, opt for 14 or 12 AWG for better results.<\/p><p>For an upgrade, try something like the <a href=\"https:\/\/www.av.com\/Cables\/AudioQuest-Rocket-11-PVC-Speaker-Cable-Black\/4GD9\" target=\"_blank\" rel=\"noopener\"><strong>AudioQuest Rocket 11<\/strong><\/a> or <a href=\"https:\/\/www.av.com\/Cables\/Chord-Company-RumourX-Speaker-Cable\/4RSQ\" target=\"_blank\" rel=\"noopener\"><strong>Chord RumourX<\/strong><\/a> - both are designed to reduce distortion and enhance detail through premium copper construction. If you need more options, our list of <strong><a href=\"https:\/\/www.av.com\/blog\/best-speaker-cables\/\" target=\"_blank\" rel=\"noopener\">favourite speaker cables<\/a><\/strong> gives you six to choose from.<\/p><p>Once you\u2019ve chosen your cable type, the next step is picking the right layout for your setup. Most speaker cables are 2-core, meaning one side carries the positive signal, the other the negative. This is standard for the majority of home systems and works perfectly well in most cases.<\/p><p>Some amps and speakers support <a href=\"https:\/\/www.av.com\/speaker-cables?page=1&filters[2016]=13020#cbls\" target=\"_blank\" rel=\"noopener\"><strong>bi-wiring<\/strong><\/a>, which uses 4-core to separate the treble and bass signals. This can offer subtle improvements in clarity and stereo separation by giving each frequency range its own path. That said, it\u2019s not essential. Most bi-wireable speakers include metal bridging plates between terminals, so 2-core cable remains a reliable choice.<\/p><p>If you\u2019re routing cable through walls or ceilings, choose one that meets safety standards like the <a href=\"https:\/\/www.av.com\/Cables\/QED-QX16-2-Flame-Retardant-PVC-Speaker-Cable-White\/4AYA\" target=\"_blank\" rel=\"noopener\"><strong>QED QX16\/2<\/strong><\/a>, which features a flame-retardant, in-wall-rated jacket.<\/p><p>We\u2019ve had to keep it brief here, but for more details, including what plug to use, check out our full <a href=\"https:\/\/www.av.com\/blog\/how-to-wire-speakers\/\" target=\"_blank\" rel=\"noopener\"><strong>guide to wiring speakers<\/strong><\/a>.<\/p><hr \/><h4>2.

One common type is <a href=\"https:\/\/www.av.com\/stereo-phono-rca-cables?page=1&filters[2133]=21596\" target=\"_blank\" rel=\"noopener\"><strong>RCA to 3.5mm<\/strong><\/a>, like the <strong><a href=\"https:\/\/www.av.com\/Cables\/QED-Connect-35mm-Jack-Phono-15m\/4MMR\" target=\"_blank\" rel=\"noopener\">QED Connect 3.5mm to RCA cable<\/a><\/strong>, which is perfect for linking hi-fi gear to portable devices, desktop DACs, or anything with a headphone-style mini-jack output.<\/p><p>At the other end of the spectrum, you might come across <a href=\"https:\/\/www.av.com\/stereo-phono-rca-cables?page=1&filters[2133]=21597\" target=\"_blank\" rel=\"noopener\"><strong>RCA to XLR<\/strong><\/a>, such as the <strong><a href=\"https:\/\/www.av.com\/Cables\/Chord-ClearwayX-2XLR-to-2RCA-Cable-1m\/4QHD\" target=\"_blank\" rel=\"noopener\">Chord ClearwayX RCA to XLR cable<\/a><\/strong>. This type is useful if you're bridging between unbalanced outputs and balanced inputs. Just note that while it adapts the connection, it doesn\u2019t create a true balanced signal.<\/p><p>Rule of thumb? Spend about 5\u201310% of your system budget on cables. Enough to avoid weak links - no need to go wild. Check out our guide to the <strong><a href=\"https:\/\/www.av.com\/blog\/best-rca-cables\/\" target=\"_blank\" rel=\"noopener\">best RCA cables<\/a><\/strong> if you're unsure.<\/p><hr \/><h4>4. XLR cables<\/h4><p><strong><img class=\"alignright size-medium wp-image-46558\" src=\"https:\/\/www.av.com\/blog\/wp-content\/uploads\/2025\/07\/Fisual-Havana-Custom-Made-XLR-Cable-300x300.jpg\" alt=\"Fisual Havana Custom Made XLR Cable\" width=\"300\" height=\"300\" \/>What it does:<\/strong><\/p><p>In a hi-fi context, <a href=\"https:\/\/www.av.com\/xlr-din-cables\" target=\"_blank\" rel=\"noopener\"><strong>XLR cables<\/strong><\/a> carry balanced analogue audio between generally higher-end components like DACs, amps, <a href=\"https:\/\/www.av.com\/home-cinema\/av-processors-preamplifiers\" target=\"_blank\" rel=\"noopener\"><strong>processors<\/strong><\/a>, and more; Low-noise, long runs, better than RCA.<\/p><p><strong>What to know & which to choose:<\/strong><\/p><p>We\u2019ve touched on balanced cables before, but here\u2019s a quick reminder: XLR uses three pins - one for ground and two for the signal (one normal, one inverted). When the inverted signal flips back at the receiving end, any interference picked up along the way gets cancelled out.<\/p><p>You don\u2019t have to spend a fortune to get started. The <a href=\"https:\/\/www.av.com\/Cables\/Fisual-Havana-Custom-Made-XLR-Cable-Pair-1m\/4MY3\" target=\"_blank\" rel=\"noopener\"><strong>Fisual Havana XLR<\/strong><\/a> is a great entry-level option - ideal if you're just trying out XLR for the first time.<\/p><p>If you\u2019re after something more refined, the <a href=\"https:\/\/www.av.com\/Cables\/Chord-ClearwayX-2RCA-to-2XLR-Cable-1m\/4QHB\" target=\"_blank\" rel=\"noopener\"><strong>Chord ClearwayX Cable<\/strong><\/a> is a sizable step up in build and performance, designed to maximise detail and overall system transparency.<\/p><p>And just so there\u2019s no confusion - don\u2019t mix up XLR with <a href=\"https:\/\/www.av.com\/xlr-din-cables?page=1&filters[1714]=13272\" target=\"_blank\" rel=\"noopener\"><strong>DIN<\/strong><\/a>. They might look vaguely similar, but DIN is unbalanced and typically found on specific legacy gear, like older <a href=\"https:\/\/www.av.com\/naim-audio\" target=\"_blank\" rel=\"noopener\"><strong>Naim<\/strong><\/a> systems. For everything else, RCA remains the alternative.<\/p><hr \/><h4>5. Optical and coaxial cables<\/h4><p><strong><img class=\"alignright size-medium wp-image-46559\" src=\"https:\/\/www.av.com\/blog\/wp-content\/uploads\/2025\/07\/Fisual-Pearl-Mini-Toslink-To-Toslink-Optical-Cable-1m-300x300.jpg\" alt=\"Fisual Pearl Mini Toslink To Toslink Optical Cable 1m\" width=\"300\" height=\"300\" \/>What it does:<\/strong><\/p><p>We\u2019ve grouped these two because - just like most amps do - you\u2019ll usually find the <a href=\"https:\/\/www.av.com\/optical-cables\" target=\"_blank\" rel=\"noopener\"><strong>optical<\/strong><\/a> and <a href=\"https:\/\/www.av.com\/coaxial-cables\" target=\"_blank\" rel=\"noopener\"><strong>coaxial<\/strong><\/a> ports sitting side by side. Both are digital audio connections, used to send sound from a source (like a CD player, streamer, or <a href=\"https:\/\/www.av.com\/tvs\" target=\"_blank\" rel=\"noopener\"><strong>TV<\/strong><\/a>) to an amp or DAC.<\/p><p><strong>What to know & which to choose:<\/strong><\/p><p>Because they transmit digital signals\u00a0 -1s and 0s - they\u2019re much less prone to interference than analogue cables.<\/p><p><strong>Optical (aka TOSLINK) cables<\/strong> use light to send the signal through a fibre optic strand. Since they don\u2019t carry electricity, they\u2019re immune to electrical interference - great in setups packed with gear or power cables. Just be gentle with them: sharp bends or heavy pressure can damage the fibre inside.<\/p><p><strong>Coaxial cables<\/strong> do the same job over a copper core, using RCA-style plugs. They\u2019re generally tougher and more flexible than optical, and can carry slightly more bandwidth - but in everyday use, the difference is negligible.<\/p><p>You might also come across <a href=\"https:\/\/www.av.com\/optical-cables?page=1&filters[2133]=22975,22484\" target=\"_blank\" rel=\"noopener\"><strong>TOSLINK to mini-TOSLINK<\/strong><\/a>, which works the same way but with a smaller plug - often found on laptops or compact DACs.<\/p><p>If your gear has both options, either will work well for stereo or basic surround formats like Dolby Digital. Just pick what fits your layout best.<\/p><p>One final tip: neither supports lossless surround (like Dolby TrueHD or uncompressed Atmos). For that, you\u2019ll want <a href=\"https:\/\/www.av.com\/hdmi-cables\" target=\"_blank\" rel=\"noopener\"><strong>HDMI<\/strong><\/a>.<\/p><p>There's no wrong answer here. Just aim for something well-built and don't overspend.<\/p><hr \/><h4>6. HDMI cables<\/h4><p><strong><img class=\"alignright size-medium wp-image-46560\" src=\"https:\/\/www.av.com\/blog\/wp-content\/uploads\/2025\/07\/preview-2025-07-25T162940.592-300x300.jpg\" alt=\"Audioquest Vodka eARC 48Gbps High Speed HDMI Cable 0.6m\" width=\"300\" height=\"300\" \/>What it does:<\/strong><\/p><p><a href=\"https:\/\/www.av.com\/hdmi-cables\" target=\"_blank\" rel=\"noopener\"><strong>HDMI cables<\/strong><\/a> carry both video and audio through a single connection, making them a more convenient choice than audio-only digital cables like optical - especially when hooking up <a href=\"https:\/\/www.av.com\/home-cinema\/blu-ray-players\" target=\"_blank\" rel=\"noopener\"><strong>Blu-ray players<\/strong><\/a>, <a href=\"https:\/\/www.av.com\/gaming\" target=\"_blank\" rel=\"noopener\"><strong>game consoles<\/strong><\/a>, <a href=\"https:\/\/www.av.com\/smart-tv-boxes\" target=\"_blank\" rel=\"noopener\"><strong>streamers<\/strong><\/a>, and amps to your TV or <a href=\"https:\/\/www.av.com\/home-cinema\/projectors\" target=\"_blank\" rel=\"noopener\"><strong>projector<\/strong><\/a>.<\/p><p><strong>What to know & which to choose<\/strong>:<\/p><p>These days, HDMI cables do more than just get a picture on screen, and you\u2019ll likely see terms like <em>48Gbps<\/em>, <em>HDMI 2.1<\/em>, <em>ARC<\/em>, and <em>eARC<\/em> thrown around.<\/p><p>In short, <a href=\"https:\/\/www.av.com\/hdmi-cables?page=1&filters[1957]=19113\" target=\"_blank\" rel=\"noopener\"><strong>48Gbps<\/strong><\/a> means the cable can handle all the latest features: 4K at high frame rates, 8K, HDR, and surround audio formats.
