  • Best for: Audiophiles, Plex/Kodi power users, local media playback, gaming

Amazon Fire TV Cube (3rd Generation)

Amazon’s Fire TV Cube packs a powerful octa-core processor and integrates Alexa hands-free voice control directly into the device. For audio, it supports Dolby Atmos, Dolby Digital Plus, and DTS:X, making it a strong contender for immersive sound. The Fire TV Cube also includes HDMI eARC, enabling it to receive audio from your TV and send it to your sound system—useful if you have multiple input sources (cable box, game console) connected to the TV.

One standout feature is the ability to control your entire home theater via infrared blasters, so you can turn on your receiver, change its volume, and switch inputs using only your voice. The Fire TV Cube also supports HDR10+ Adaptive and Dolby Vision, but its audio decode capabilities are slightly more limited than the Shield TV Pro: it cannot pass through lossless TrueHD or DTS-HD MA from local files unless you use third-party apps with software decoding.

For casual streaming and those who rely on Alexa for smart home control, the Fire TV Cube delivers excellent audio quality on services like Netflix, Prime Video, and Disney+. It also supports Amazon Music HD with lossless streaming up to 24-bit/192 kHz.

  • Key connectivity: HDMI 2.1 with eARC, optical audio output, IR blaster, Bluetooth 5.0
  • Best for: Alexa smart home integration, casual streaming, voice-controlled setups

Roku Ultra

The Roku Ultra has long been praised for its simple, ad-free interface and broad platform support. While it may not match the audiophile-grade capabilities of the Shield TV Pro, it provides solid audio quality for most users. It supports Dolby Atmos via Dolby Digital Plus (lossless) and DTS Digital Surround pass-through. The latest model includes HDMI eARC for enhanced audio bandwidth and Bluetooth private listening—a handy feature for late-night viewing.

The Roku Ultra also features an optical audio output (TOSLINK), which can be useful for connecting older receivers that lack HDMI. It supports multichannel PCM output up to 5.1. However, it does not support lossless Dolby TrueHD or DTS-HD Master Audio, which limits high-fidelity playback from local media or high-end streaming services.

One of the biggest advantages of Roku is its universal search and compatibility with virtually every major streaming service. For listeners who prioritize clarity and consistency over specialized codecs, the Roku Ultra is a reliable workhorse. Its Dolby Audio certification ensures that most streaming content sounds clean and well-balanced.

  • Audio formats: Dolby Atmos (lossy), DTS Digital Surround, multichannel PCM (5.1), Dolby Audio
  • Key connectivity: HDMI 2.0a with eARC, optical audio, USB media player, Bluetooth 4.2
  • Best for: Ease of use, family streaming, users with older audio equipment, private listening

Understanding Advanced Audio Formats

To get the best audio from your streaming device, you need to understand the formats that matter. Dolby Atmos and DTS:X are object-based audio technologies that allow sounds to be placed in a three-dimensional space, creating a sense of immersion that traditional surround sound cannot match. These formats come in two flavors: lossy (compressed, used by streaming services) and lossless (uncompressed, found on Blu-ray discs and high-resolution downloads).

Streaming platforms like Netflix, Disney+, and Apple TV+ deliver Dolby Atmos using Dolby Digital Plus, which is a lossy format. To experience the full lossless version—Dolby TrueHD with Atmos metadata—you typically need a local media server and a device like the NVIDIA Shield TV Pro that can decode it. Similarly, DTS:X is usually delivered losslessly via DTS-HD Master Audio. For music streaming, Dolby Atmos Music is increasingly available on services like Apple Music and Tidal; your streaming device must support it for proper playback.

The Critical Role of HDMI eARC and ARC

ARC (Audio Return Channel) and the newer eARC (enhanced Audio Return Channel) are HDMI features that let your TV send audio back to a soundbar or AV receiver over the same HDMI cable used for video input. This is crucial because many modern TVs have limited audio processing—they can only output compressed formats over optical. With eARC, your streaming device connected directly to your TV can pass lossless audio (TrueHD, DTS-HD MA) and uncompressed multichannel PCM to your sound system seamlessly.

When choosing a streaming device, look for one that supports HDMI 2.1 with eARC to future-proof your setup. The Apple TV 4K and Fire TV Cube both offer eARC, while the Shield TV Pro uses HDMI 2.0b but still supports lossless audio pass-through when connected directly to an AV receiver. If you use a soundbar without eARC, you can still get Dolby Atmos via compressed formats—but for the highest fidelity, eARC is essential.

Choosing the Right Streaming Device for Your Home Theater

Your final choice depends on your specific audio setup and priorities. If you own a high-end AV receiver with Dolby Atmos speakers and you play back lossless audio from local media, the NVIDIA Shield TV Pro is the undisputed king. If you prefer a seamless ecosystem with Apple devices and listen to lossless Apple Music spatial audio, the Apple TV 4K is the logical pick.

For those who rely on voice assistants and want an all-in-one remote that controls everything—including your soundbar’s volume—the Fire TV Cube offers convenience with solid audio. And if simplicity, reliability, and private listening are your top priorities, the Roku Ultra provides a hassle-free experience without sacrificing basic audio quality.

Setup Tips for Optimal Audio Playback

  • Use the shortest, highest-quality HDMI cable you can afford. For lossless audio, an HDMI 2.1 certified cable rated for 48 Gbps is ideal, but even a good HDMI 2.0 cable can handle Dolby TrueHD over short distances.
  • Enable HDMI eARC on your TV and sound system. Check your TV’s audio settings and set the HDMI ARC/eARC mode to “Auto” or “Enhanced.” Ensure your soundbar or receiver is connected to the correct eARC port.
  • Turn off audio processing in your TV. Many TVs apply additional processing (like virtual surround or volume leveling) that can degrade the signal. Set the TV to “Pass-through” or “Bitstream” output mode.
  • Verify that your streaming service supports the highest quality audio. For example, Netflix requires the Premium plan for Dolby Atmos. Apple Music streams lossless at up to 24-bit/48 kHz, but you must enable it in settings.
  • Position your speakers correctly. Object-based audio relies on accurate speaker placement. Follow your soundbar or receiver’s setup guide, and use the calibration microphone if available.

Ultimately, the best streaming device for high-quality TV audio is the one that matches your system and your listening demands. By choosing a device that supports the right formats, includes eARC, and integrates with your existing hardware, you can unlock a cinematic audio experience without leaving your couch.
