HDMI is a constantly evolving standard too, with new and improved versions offering more bandwidth and greater capacity to carry more channels of audio, such as Dolby Atmos and DTS:X soundtracks. An entry-level cable like the AudioQuest Pearl HDMI will suit a wide range of systems. You'll find HDMI inputs and outputs a firm fixture on the best TVs, Blu-ray players, AV receivers and, increasingly, soundbars. Unlike optical and coaxial, there isn’t really a similar rival out there. It boasts much higher bandwidth than optical, allowing for playback of lossless audio formats such as Dolby TrueHD and DTS-HD Master Audio. Launched in 2002, the biggest benefit of HDMI is it’s a one-size-fits-all connection for video and audio. Then there's the threat of damage if an optical cable is bent too tightly. An optical connection also can’t support more than two channels of uncompressed PCM audio. Like coaxial, one of the issues with optical is that it doesn’t have enough bandwidth for the lossless audio formats such as Dolby TrueHD or DTS-HD Master Audio soundtracks found on most Blu-rays and 4K Blu-rays. Optical inputs are found at the amplification or DAC end, e.g. Something like the QED Performance Graphite Optical is a good entry-level option.Īlthough HDMI has taken over as the main socket of choice for many manufacturers, optical outputs are still common on games consoles, Blu-ray players, set-top boxes and televisions. Optical cables with a Toslink (Toshiba Link) connector slot into a matching socket on both source and receiver. Traditionally, in a home cinema environment, optical connections tend to be used to transmit compressed Dolby Digital and DTS surround sound. An optical cable doesn’t allow noise to pass from source to DAC circuitry like a coaxial can, and so makes sense to use this socket when connecting straight into the DAC of a soundbar or AV receiver.

The 22 best Dolby Atmos movie scenes to test your home cinema surround sound systemĪn optical digital connection uses the medium of light to transmit data through a cable’s optical fibres (which can be made from plastic, glass or silica).So, in a modern home cinema setting, its uses are quite limited. Unfortunately, using a coaxial connection enables noise to travel along the cable from the source to your amplifier.Īlso, coaxial doesn't have the bandwidth required to support high-quality surround sound formats such as Dolby TrueHD, DTS-HD Master Audio, Dolby Atmos and DTS:X. Noise is bad news when it comes to sound quality, but it exists in all AV components to one degree or another. The main downside to a coaxial digital connection is the potential transfer of electrical noise between your kit.

Our pick of the best AV receivers: brilliant home cinema amplifiers.

That's because it has greater bandwidth available, meaning it can support higher quality audio up to 24-bit/192kHz. An entry-level cable like the QED Performance Coaxial will do a fine job for most.Ĭoaxial might not be as widespread as its rival optical connection these days, but you'll still find it at the back of certain AV receivers, integrated amplifiers and TVs.Īnd, in our experience, compared to optical, a coaxial connection does tend to sound better. They look similar and can work, but an analogue interconnect has different impedance values from a digital one (50 ohm versus 75 ohm), so won’t work as well. But don’t be tempted to try and use a standard RCA phono cable in place of a dedicated coaxial digital cable.
