Audioquest Cinnamon 48 HDMI Cable - 3.0 Meter

A Cable Built for the Next Decade of Video, Not Just This One

The AudioQuest Cinnamon 48 is an HDMI cable certified for the full 48Gbps that HDMI 2.1 allows. HDMI Licensing itself tested and approved it as Ultra High Speed. That headroom matters for 8K/60 and 4K/120 sources today. It also means the cable won't be the weak link if your next TV or receiver asks for more bandwidth than your current gear does. This listing is the 0.75-meter length; longer runs are available if you need more reach.

Inside the jacket, all 19 conductors are solid silver-plated Long-Grain Copper. They're run in a direction-controlled layout meant to reduce distortion from strand interaction. A metal-layer shield wraps the four FRL pairs and the eARC pair, the parts of the cable carrying the most bandwidth-sensitive signals.

Noise Control That Targets Where It Actually Happens

AudioQuest calls this approach Level 3 Noise-Dissipation. A carbon-loaded synthetic mesh surrounds the conductors and gives stray radio-frequency energy somewhere to go besides your signal path. Combined with the direction-controlled conductors, the goal is a cleaner path for both the video and the audio sharing the same wire.

That matters most for eARC, where the cable carries uncompressed, lossless multichannel audio back from your TV to a soundbar or receiver. The Cinnamon 48 also supports Dynamic HDR and the gaming features in HDMI 2.1: variable refresh rate, auto low-latency mode, and quick frame transport. It stays backward compatible with older 4K gear too, so upgrading now doesn't lock out anything you already own.

What Reviewers Are Saying

The Audio Tailor reviewed the Cinnamon 48 on March 15, 2025, calling out its readiness for demanding sources: "Built to deliver an astounding 48Gbps bandwidth, this HDMI cable is ready to handle the demands of professional 10K Ultra-HD video." The review also praised the internal layout: "the balanced design—with independent 12Gbps audio/video pairs—guarantees that every detail is rendered with exquisite clarity." It closed by calling the cable "a worthy investment for anyone passionate about both picture and sound quality."

Who Is This Cable Best For?

• Anyone running a current or upcoming 8K display. Full 48Gbps certification keeps the cable from being the bottleneck.
• Gamers on next-gen consoles or a high-end PC. VRR, ALLM, and quick frame transport are all supported for smoother gameplay.
• Anyone sending audio back to a soundbar or AVR over eARC. The shielded eARC pair carries uncompressed, lossless multichannel sound cleanly.
• Home theater builds where the cable run is short. This 0.75-meter length suits a tight rack; longer versions cover longer runs.
• Not the right fit for permanent in-wall runs. This is a standard jacketed cable, not in-wall rated, so check local code first.

What Length Do You Need?

The Cinnamon 48 is available from 0.6 meters up to 5 meters. Measure the actual path the cable will take, including slack for routing around a rack or through furniture, not just the straight-line distance to your display. A cable that's slightly too long is easier to manage than one that's just short.

Every length carries the same conductors, shielding, and 48Gbps certification. Picture and sound quality don't change as the cable gets longer within this range. AudioQuest backs the Cinnamon 48 with a limited lifetime warranty against defects in materials or workmanship.
