I am about to upgrade the infrastructure in my home. I’m currently using a Mac Mini (late 2012) with PlexConnect as my PMS and two Apple TV 3 via PlexConnect. All my media is stored on my Mac Mini internal drive.
I’m considering upgrading my ATV3 to Roku for a few reasons:
i) my logitech remote won’t play well with the ATV4 swipes for FF and RW functions
ii) ATV3 doesn’t have 4K capabilities…which annoys me especially since I just upgraded to an LG OLED TV
My question for the forum is simple enough…is there a material difference between clients (ie. ATV3/ATV4 vs Roku) in terms of transcoding might be supported/required? Should I upgrade to a Roku or an ATV4?
Definitely check out the NVIDIA Shield TV. It is more expensive than some other options, but it also has more capabilities.
ATV
First, ATV4 doesn’t support 4K, so mark that one off your list unless you’re heavily invested in the Apple ecosystem.
If you’ve a huge iTunes audio library you might want to keep the ATV3 around just for that. I still use my ATV3 to play music from my iTunes library, and IMHO, the ATV UI beats the Roku and Android TV (NVIDIA, Amazon Fire) devices hands down.
However, the ATV3 & 4 are both limited when it comes to playing movies - no 4K, no DTS, and none of the lossless audio codecs like DTS-HD, Dolby TrueHD, & Dolby Atmos. Given its capabilities, the ATV4 is expensive compared to other options such as Roku Ultra and NVIDIA Shield.
WRT audio playback the ATV and Roku both support Apple Lossless audio. The Amazon Fire and NVIDIA Shield do not. Apple Lossless played back on Android TV is transcoded to MP3. The ATV does not support FLAC (unsure if that is a requirement).
Amazon Fire TV
A nice box, but lacks in codec support, specifically DTS and the previously mentioned lossless codecs (no native support and no passthru). Outside of Plex, the Fire TV does not support for high bit rate audio - FLAC 24bit/96kHz, DSD, etc - if that is important to you. It supports 4K, but only at 30p, and doesn’t support HDR.
Here’s some tech details: Fire TV Device Specifications: Overview | Amazon Fire TV.
Roku
If you want 4K and HDR, you’re looking at the Premier+ or Ultra.
Here’s a nice comparison: https://image.roku.com/ww/docs/compare-chart-products-en-us.pdf
It is unclear if the Roku supports passthrough for DTS-HD MA lossless audio (I could not find a definitive answer). It does support passthrough of Dolby TrueHD & Atmos. I could not find info on native high bit rate audio support for Roku devices. Roku does support Apple Lossless audio.
NVIDIA Shield
The NVIDIA Shield TV natively plays or passes through almost anything you can throw at it. Spec sheet says it handles 4K HDR as well (I don’t have a 4K tv). Scroll down to “See Full Specs:” SHIELD TV Streaming Media Players | NVIDIA
My Shield TV is connected to a Denon AVR. It passes through Dolby Atmos, Dolby TrueHD, DTS-HD, DTS-X without issue, along with the older formats such as Dolby Digital and DTS. It also handles 24 bit FLAC files. The only thing I’ve found it must transcode is VC-1 video and Apple Lossless audio. Very few movies are delivered in VC-1 video, and I’m not aware of any streaming box that plays it natively. WRT Apple Lossless audio, I’m keeping my ATV3 around for that (I could manually transcode the files to FLAC, but keeping things in ALAC is easier for now).
Summary
The NVIDIA Shield TV is the most expensive, but it is also the most capable. It support 4K, HDR, and can passthrough all current lossless audio streams. It natively plays everything but Apple Lossless audio and VC-1 video and supports 24bit FLAC music. It has the highest end CPU and can easily transcode anything if needed.
If you don’t need everything the Shield TV offers or if price is a concern, then go with a Roku Premier+ or Ultra. The Rokus support 4K, HDR, and can passthrough Dolby TrueHD & Atmos audio streams. They also support Apple Lossless audio w/o transcoding to another format.
The Amazon FireTV is nice, but for the price you’re probably better off going with a Roku Premier+, as the Premier+ supports 4K60p, HDR10, and more audio codecs.
The ATV4 seems too limited outside of the Apple ecosystem. The lack of 4K support is also a bit of a deal killer. Especially since it costs the same as a Roku Ultra or NVIDIA Shield (depending on the model).
