AudioQuest Cinnamon 48 4K/8K/10K HDMI Cable at Vinyl Sound Toronto Canada

The AudioQuest Cinnamon 48 is a 48Gbps HDMI 2.1 cable from AudioQuest (Irvine, California, USA), available at Vinyl Sound in Toronto, Canada. Built for next-generation home theatre and gaming systems, the Cinnamon 48 delivers 48Gbps bandwidth supporting 8K/60, 4K/120, and professional 10K Ultra HD video with Dynamic HDR and eARC, using Solid 1.25% Silver-Plated Long-Grain Copper conductors on all A/V and eARC signal pairs. AudioQuest's Level-2 Noise Dissipation places a dedicated metal layer around the four Fixed Rate Link and eARC pairs, with directional noise control extended to all 19 HDMI conductors, and a 0.5% silver ground reference stabilizes the electrical reference plane throughout the cable.

48Gbps Bandwidth and 8K/10K/4K/120 Video Performance

The AudioQuest Cinnamon 48 carries the full 48Gbps bandwidth specified by HDMI 2.1, enabling 8K video at 60 frames per second, 4K at 120 frames per second, and professional 10K Ultra HD resolution. Dynamic HDR formats including HDR10+, Dolby Vision, and HLG are fully supported, as are Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM) for gaming applications. Dedicated eARC conductors built from the same 1.25% Silver-Plated Long-Grain Copper as the primary A/V pairs support lossless audio return from compatible displays to AV receivers and soundbars. The Cinnamon 48 is a significant step forward from AudioQuest's 18Gbps HDMI 2.0 cables, providing the bandwidth headroom required for current and near-future 8K and high-frame-rate 4K source and display combinations.

Level-2 Noise Dissipation and Silver-Plated Conductors

AudioQuest's Level-2 Noise Dissipation places a dedicated metal layer specifically around the four Fixed Rate Link pairs and the eARC pair, the conductors carrying the highest-bandwidth and most noise-sensitive signals in an HDMI 2.1 cable. This targeted metal-layer shield provides an additional stage of RF noise absorption at the critical signal conductors beyond the directional noise control applied to all 19 HDMI conductors, including A/V signal pairs, eARC, all ground-reference drains, and control and power conductors. By preventing RFI captured at secondary conductors from reaching and modulating the ground reference, Level-2 NDS reduces the low-level noise contamination that degrades picture sharpness and audio clarity in high-bandwidth HDMI systems. The 1.25% Silver-Plated Long-Grain Copper conductors provide lower grain-boundary distortion than unplated copper, and the 0.5% silver ground reference maintains a stable, low-resistance reference plane throughout the cable run.

Key Features

• Solid 1.25% Silver-Plated Long-Grain Copper Conductors: All A/V and eARC signal pairs use solid LGC conductors with a 1.25% silver plating layer for reduced grain-boundary distortion and improved high-frequency signal integrity.
• Level-2 Noise Dissipation: Dedicated metal layer around the four FRL and eARC pairs provides targeted RF noise absorption at the most signal-critical conductors in the cable.
• All 19 Conductors Directionally Controlled: Signal, eARC, ground-reference, control, and power conductors are all treated for directional RF noise dissipation to prevent cross-conductor noise coupling.
• 0.5% Silver Ground Reference: Silver-alloy ground conductors maintain a stable, low-resistance reference plane for consistent signal integrity across the full cable length.
• Dynamic HDR Support: Compatible with HDR10+, Dolby Vision, and HLG for scene-by-scene and frame-by-frame HDR metadata delivery.

Frequently Asked Questions

What is the AudioQuest Cinnamon 48 HDMI cable?

The AudioQuest Cinnamon 48 is a 48Gbps HDMI 2.1 cable built with Solid 1.25% Silver-Plated Long-Grain Copper conductors, a 0.5% silver ground reference, and Level-2 Noise Dissipation featuring a dedicated metal layer around all four FRL and eARC signal pairs. It supports 10K, 8K/60, and 4K/120 video with Dynamic HDR, VRR, ALLM, and eARC, and applies directional noise control to all 19 HDMI conductors. It is available at Vinyl Sound in Toronto, Canada.

How does the AudioQuest Cinnamon 48 compare to the AudioQuest Forest 48 or Carbon 48 HDMI cables?

The AudioQuest Cinnamon 48 sits between the Forest 48 and the Carbon 48 in the AudioQuest HDMI 2.1 lineup. The Forest 48 uses Level-1 Noise Dissipation with directional control on all 19 conductors but without the additional metal layer around the FRL and eARC pairs. The Cinnamon 48 adds that metal-layer shield at the critical signal conductors as Level-2 NDS, and steps up to 1.25% Silver-Plated LGC conductors and a 0.5% silver ground reference. The Carbon 48 advances further with 5% Silver-Plated conductors, a 1.25% silver ground reference, and Level-3 NDS featuring a carbon layer sandwiched between metal layers for maximum noise absorption. The Cinnamon 48 is the appropriate choice for high-performance 8K and 4K/120 home theatre systems where the Forest 48 is the starting point and the Carbon 48 is the reference-level option.

Does the AudioQuest Cinnamon 48 support 4K/120 gaming?

Yes, the AudioQuest Cinnamon 48 fully supports 4K at 120 frames per second, the native output of the PlayStation 5 and Xbox Series X for compatible titles and displays. Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM) are both supported, reducing screen tearing and input lag for gaming applications. The 48Gbps bandwidth of the Cinnamon 48 provides the headroom required to carry 4K/120 with HDR simultaneously, which is the most demanding signal combination produced by current gaming hardware.

What is Level-2 Noise Dissipation and how does it differ from Level-1?

AudioQuest's Level-2 Noise Dissipation adds a dedicated metal shielding layer specifically around the four Fixed Rate Link pairs and the eARC pair in addition to applying directional noise control to all 19 HDMI conductors. Level-1 Noise Dissipation, used on cables such as the Blueberry 18G and Forest 48, applies directional noise control to all 19 conductors but does not add the targeted metal layer around the critical FRL and eARC pairs. The additional metal layer in Level-2 provides a second stage of RF noise absorption at the highest-bandwidth signal conductors, reducing the noise that reaches the ground reference from these pairs and improving signal integrity at 48Gbps data rates.

What is eARC and does the AudioQuest Cinnamon 48 support it?

eARC, or enhanced Audio Return Channel, is an HDMI 2.1 feature that allows a television to send lossless audio back to an AV receiver or soundbar over the same HDMI cable used for video. Unlike the original ARC, which was restricted to compressed audio formats, eARC supports Dolby TrueHD, DTS-HD Master Audio, and object-based formats including Dolby Atmos and DTS:X at full lossless quality. The AudioQuest Cinnamon 48 dedicates a pair of Solid 1.25% Silver-Plated Long-Grain Copper conductors to the eARC signal and includes those conductors in the Level-2 Noise Dissipation metal-layer treatment.

Where can I buy the AudioQuest Cinnamon 48 HDMI cable in Toronto or Canada?

The AudioQuest Cinnamon 48 HDMI cable is available at Vinyl Sound, an authorized AudioQuest dealer in Toronto, Canada. Vinyl Sound carries the full AudioQuest HDMI 48G lineup in-store and online, with complete manufacturer warranty support for Canadian customers.

Is the AudioQuest Cinnamon 48 backward compatible with HDMI 2.0 devices?

Yes, the AudioQuest Cinnamon 48 is fully backward compatible with HDMI 2.0 and HDMI 1.4 devices. HDMI cables are passive conductors and the 48Gbps bandwidth rating represents the maximum the cable can carry, not a minimum requirement. The Cinnamon 48 will operate correctly with any device regardless of its HDMI version, and its superior conductor and noise-dissipation design benefits lower-bandwidth signals as well, providing cleaner transmission even when the full 48Gbps capability is not in use.
