For most people, "good audio" means their TV doesn't sound tinny. For audiophiles, it means correct lossless codec passthrough, verified bitstream integrity, and zero processing artifacts between the source and the speaker drivers.
Streaming devices are the weak link most audiophiles don't interrogate carefully enough. Here's what actually matters — and which devices get it right.
What Audiophiles Need in a Streaming Device
Lossless audio passthrough (Dolby TrueHD, DTS-HD MA): The streaming device must pass the lossless bitstream through HDMI to your AV receiver or pre/pro for decoding. Devices that decode internally and re-encode before output compromise quality. The correct behavior is bitstream passthrough — unmodified.
Dolby Atmos via TrueHD (not just DD+): Most streaming Atmos is delivered in Dolby Digital Plus — a lossy format at 640 kbps to 1.5 Mbps. Dolby TrueHD Atmos (lossless) runs at up to 18 Mbps. Several streaming services now deliver TrueHD Atmos on select titles. Your device must support the TrueHD container to access it.
DTS:X and DTS-HD support: Some AV systems are calibrated and optimized for DTS processing. Not all streaming devices support DTS formats — this is a real differentiator.
HDMI 2.1 for eARC: Enhanced Audio Return Channel (eARC) over HDMI 2.1 supports lossless audio from TV to receiver — necessary if your AV receiver connects via the TV's ARC port rather than directly to the streaming device.
No audio processing or upmixing at the device level: The streaming device should pass audio through without modification. Some devices apply their own processing (bass management, dialogue enhancement) before sending to the receiver. Audiophiles want raw passthrough.
Top Pick: Apple TV 4K (Wi-Fi + Ethernet)
For audiophiles whose systems are calibrated around Dolby processing — Dolby Atmos, Dolby TrueHD, Dolby Surround — the Apple TV 4K is the best streaming device available. It is the only mainstream streaming device that correctly passes Dolby TrueHD Atmos (lossless) through HDMI without re-encoding.

- No Dolby Vision on YouTube
- Premium price ($130+)
- Best in Dolby-centric systems only
Configuring Apple TV 4K for Audiophile Setups
The default Apple TV 4K audio settings are not optimal for audiophile use. Configure manually:
Settings → Video and Audio → Audio Format:
- Set to "Auto (Dolby Atmos)" if your AV receiver supports Dolby Atmos
- Set to "Dolby Digital 5.1" only if your receiver doesn't support Atmos
Settings → Video and Audio → Audio Mode:
- Set to "Best Quality Available" — this forces TrueHD when available vs. the lossy DD+ fallback
Settings → Video and Audio → Reduce Loud Sounds:
- Turn OFF — this applies dynamic range compression, which audiophiles never want
Settings → Video and Audio → Match Content:
- Turn ON both "Match Dynamic Range" and "Match Frame Rate" — this forces the Apple TV to switch its output to match the content's native frame rate and dynamic range, preventing any upconversion artifacts
The TrueHD Atmos Source: Apple TV+
Apple TV+ is the primary streaming service that delivers Dolby TrueHD Atmos. Select titles — including Apple Original films — are mastered and delivered in TrueHD Atmos, matching the lossless audio you'd get from a 4K Blu-ray.
Netflix Premium, Disney+ Premium, and Max Ultimate deliver Dolby Atmos in Dolby Digital Plus (lossy). This is still excellent spatial audio, but at lower bitrate than TrueHD.
For an audiophile optimizing for the best possible streaming audio:
- Apple TV 4K → HDMI directly to AV receiver (bypass TV completely)
- AV receiver decodes TrueHD Atmos natively
- Enable "Best Quality Available" in Apple TV audio settings
- Subscribe to Apple TV+ for TrueHD Atmos source material
DTS-Capable Alternative: NVIDIA SHIELD TV
If your AV system is calibrated around DTS processing — DTS:X, DTS-HD Master Audio, Neural:X upmixing — the NVIDIA SHIELD TV is the only mainstream streaming device that supports the full DTS codec suite.

Why DTS Matters (and Why Apple TV Doesn't Support It)
Apple has never licensed DTS audio formats on its platforms — a policy dating to the early iTunes era. On Apple TV 4K, any DTS content in a local file or Plex stream will be re-encoded to PCM (stereo or multi-channel) before output. This is not lossless — it loses the DTS object metadata and surround encoding.
If your AV receiver is one of these DTS-focused models:
- Marantz with DTS:X processing
- Denon with DTS Neural:X
- Yamaha with DTS:X
...then the NVIDIA SHIELD TV is the correct choice. It passes DTS:X bitstream through HDMI, and your receiver decodes it natively with full object audio.
SHIELD TV and Local Lossless Audio
Audiophiles often have local libraries: FLAC albums, lossless Blu-ray audio rips, hi-res downloads from HDtracks or Qobuz. The NVIDIA SHIELD TV running Plex Media Server can:
- Serve local FLAC, ALAC, and DTS-HD MA files to any room in the house
- Pass DTS-HD MA and Dolby TrueHD audio through HDMI from local files
- Act as a Roon endpoint (with the Roon app on Android TV) for whole-home hi-res audio
- Transcode formats your other devices can't handle directly
This makes the SHIELD TV a combined streaming device and local media server — an audiophile home system hub, not just a Netflix box.
Budget Option: Roku Ultra
For audiophiles on a tighter budget, the Roku Ultra supports Dolby Atmos passthrough and handles DD+ Atmos correctly. It does not support DTS or Dolby TrueHD, but for streaming-only use (no local library), Dolby Digital Plus Atmos covers the vast majority of content.

The Audiophile Streaming Chain
Signal integrity in an audiophile system depends on every link in the chain. For streaming:
text
Streaming Service → Internet → Router → Streaming Device → HDMI → AV Receiver → Amplifier → Speakers Where streaming devices can degrade audio:
- Re-encoding audio before HDMI output — the device decodes TrueHD internally and re-encodes to PCM. This loses lossless quality. Apple TV and SHIELD TV avoid this with bitstream passthrough.
- Network-induced dropouts — Wi-Fi interference causes brief signal interruptions that interrupt audio bitstreams. Use Ethernet (built-in on Apple TV 4K and SHIELD TV) to eliminate this.
- HDMI cable bandwidth limitations — HDMI 2.0 and above handles all audio formats including TrueHD Atmos without bandwidth constraints. Standard HDMI (1.4) can cause issues. Use High Speed HDMI cables.
- ARC vs. eARC — if routing audio via your TV's ARC port back to a receiver, standard ARC cannot carry TrueHD or DTS-HD. eARC (HDMI 2.1) supports lossless audio over ARC. Connect your streaming device directly to your AV receiver via HDMI when possible to bypass this entirely.
The audiophile-correct connection:
text
Streaming Device → HDMI directly to AV Receiver (not through TV)
AV Receiver → HDMI to TV (for video) This ensures the lossless audio bitstream reaches your receiver without passing through the TV's HDMI processing, which can strip lossless formats.
Streaming Services with Best Audio Quality
| Service | Maximum Audio Quality | Atmos Available |
|---|---|---|
| Apple TV+ | Dolby TrueHD Atmos (lossless) | ✓ |
| Netflix | Dolby Digital Plus Atmos | ✓ |
| Disney+ | Dolby Digital Plus Atmos | ✓ |
| Max (HBO) | Dolby Digital Plus Atmos | ✓ |
| Amazon Prime Video | Dolby Digital Plus Atmos | ✓ |
| Peacock | Dolby Digital 5.1 | Select titles |
| Tidal (HiFi) | FLAC lossless / MQA | N/A (music only) |
For the highest quality streaming audio, Apple TV+ on Apple TV 4K is the current best combination available for Dolby-centric audiophile systems.
