HDMI 2.1 introduces eARC (Enhanced Audio Return Channel) as an improvement over HDMI 2.0's ARC. By utilising the higher bandwidth capabilities of HDMI 2.1, eARC can send uncompressed multi-channel audio from your TV to your amplifier/speakers. Similarly, the higher bandwidth of the A/V channels of HDMI 2.1 also support uncompressed multi-channel audio from your source to your amplifier/speakers. The higher bandwidth of HDMI 2.1 is also suited for I2S connections to support a wider range of resolutions.

In short, yes, although, this depends on the quality of the cable and your speakers/amplifier. High quality speaker cables tend to be manufactured with 4 key areas, their conductor, dielectric, shielding and geometry. Each of these areas can optimise signal retention from your amplifier to your speakers. Cheaper speaker cables can use lower quality conductors (tin-plated copper or even steel-clad copper), with basic dielectrics (PVC), no shielding and minimal strands with no geometry. More expensive speaker cables start to introduce higher quality conductors (Oxygen-free Copper, Ohno Continuous Cast Copper, Silver-plated Copper or even Pure Silver), better dielectrics (XLPE, PTFE, Teflon etc.), different amounts of shielding (foil, ofc-braid, carbon etc) and various geometries (solid-core, different twists, higher gauges etc.). There are diminishing returns to consider between your speaker cable and your system, as well as the potential of bottle-necks in your system if you use a lower...

Yes. Build quality, conductor material, shielding, and connector quality can influence noise levels, clarity, and overall tonal balance, especially in resolving systems.

Use the shortest practical length to minimise signal loss and interference. Longer runs benefit from better shielding and low‑capacitance designs.

Yes, but turntables require low‑capacitance phono cables designed for moving‑magnet or moving‑coil cartridges. Standard line‑level RCA cables are not always suitable.

AudioQuest HDMI cables focus on signal direction control, advanced shielding, and higher‑purity conductors to reduce noise and timing errors.

They can. Reduced noise and jitter can improve audio clarity, particularly when using eARC, Dolby Atmos or other high bandwidth audio formats.

Some models are directional to optimise signal flow. Always follow the arrow markings for correct installation.

Van den Hul cables use proprietary conductor materials and carbon‑based technologies designed to reduce noise and distortion.

They are often described as smooth, natural, and detailed without sounding harsh or analytical.

Many users report improvements in clarity, dynamics, and noise floor when using high‑quality audio fuses.

They are usually fitted in Uk 3 Pin plugs, IEC inlets, or internal fuse holders within audio equipment.

Some manufacturers recommend a short running‑in period for best performance.

An external DAC can offer improved sound quality, more inputs, and support for higher‑resolution formats.

Yes. A better DAC can significantly improve clarity, detail, and timing from streaming sources.
