ThunderBird eARC-Priority Puts the Best Metal Where Your Sound Travels

AudioQuest's ThunderBird eARC-Priority is built for a TV that sends its sound to a receiver or soundbar. They are full 48Gbps cables for the picture, but the best metal goes to the eARC pair and its ground drain, the path your sound actually takes. Here that means 10% silver eARC conductors and a 10% silver ground drain, with Level-5 Noise-Dissipation.

10% silver eARC Conductors, 10% silver Ground-Reference

AudioQuest says the eARC data pair and the ground-reference drain in ThunderBird eARC-Priority use 10% silver, the same ingredients as its ThunderBird 48. Graphene joins the carbon layer around the data pairs and a global carbon layer wraps every conductor, its Level-5 Noise-Dissipation.

A Full 48Gbps Cable for the Picture

AudioQuest says these are full-on 48-Series HDMI cables with the 48Gbps bandwidth for 8K and 10K video. The main audio/video pairs use solid 0.5% silver-plated Long-Grain Copper with Level-3 Noise-Dissipation. The eARC pair and the ground drain use the same ingredients as the matching 48 cable.

The HDMI Plugs, Explained

ThunderBird eARC-Priority ends in a full-size HDMI plug at each end. HDMI is the flat 19-pin plug on every TV, projector, receiver and console. One cable carries picture, sound and the control signals that let the devices talk. Arrows on the plugs show which way to run it.

Who Is This HDMI Cable Best For?

  • You want the value rung of AudioQuest's eARC line — ThunderBird eARC-Priority brings graphene and 10% silver drains to the pair that carries your sound
  • Your TV is the hub and the receiver hangs off it — the eARC pair carries every soundtrack back to the receiver, so that pair gets the best metal in the cable
  • You play Atmos and lossless multichannel from apps on the TV — eARC carries lossless multichannel, and the picture pairs still deliver the full 48Gbps
  • You game on a PS5 or Xbox Series X through the TV — 4K/120, VRR and ALLM are all within the cable's certified bandwidth
  • Your sound comes from a disc player or streamer straight into the receiver — the eARC-Priority design spends its best metal on the return channel from the TV, which that setup never uses. Choose AudioQuest ThunderBird 48 instead

How Does It Connect to Your System?

Run the cable from the socket marked eARC or ARC on your TV to the eARC input on your receiver or soundbar. Follow the arrows AudioQuest prints on the plugs. Then turn eARC on in the sound menu of the TV and of the receiver.

Then press play. Other and longer lengths available. Call for prices.

Pairs Well With

An HDMI cable is one link in a home theater chain. It usually joins these categories.

  • Home Theater Receivers — the hub most HDMI cables plug into
  • Digital-to-Analog Converters — for HDMI audio links and I2S over HDMI
  • Speaker Cables — the last link after the receiver
  • Power Cables — clean power for the display and the receiver

Frequently Asked Questions

What is eARC?

In AudioQuest's words, the Audio Return Channel sends audio from the TV to a soundbar, receiver or ARC input. The enhanced version, eARC, is easier to use and enables lossless multichannel sound. Both the TV and the receiver need an eARC socket.

What is Level-5 Noise-Dissipation?

AudioQuest adds high-loss graphene to the carbon layer sandwiched between metal around the four data pairs and the eARC pair. A second, global carbon layer then wraps all the conductors, so noise meets two barriers before ground.

What does 48Gbps get me?

AudioQuest says its 48 cables can transfer up to professional 10K Ultra HD video, support Dynamic HDR, and have the conductors and bandwidth eARC needs. Four balanced audio/video pairs each carry 12Gbps to reach the 48Gbps HDMI 2.1 rate.

Why plate copper with silver?

AudioQuest says increasingly thick layers of silver are applied to its Long-Grain Copper to improve Noise-Dissipation. Placing the superior metal on the outside of the conductor produces the greatest benefit, which it calls a superbly cost-effective way to maximize a digital cable.

What warranty does AudioQuest give?

A limited lifetime warranty to the original owner, for cables bought from an authorized US dealer such as Audio Advisor. AudioQuest will repair or replace a defective cable that has not been abused. Keep your proof of purchase.

Is there a step up?

AudioQuest Dragon eARC-Priority is the top of the line. It moves the eARC pair and drain to 100% silver and adds the 72-volt Dielectric-Bias System, Level-7 Noise-Dissipation.
