Roon vs Kodi for a Lossless Music Library
Roon gets mentioned a lot in the same forums and threads where people talk about disc ripping and lossless audio. It’s the other serious option for a hi-res music library, and if the foobar post left you curious whether there’s a good alternative to Kodi, Roon is the natural next question.
The short answer: Roon is genuinely excellent software but also the wrong choice for anyone who cares primarily about Atmos passthrough. The longer answer involves a subscription fee, a well thought out beautiful interface, a fundamental architectural difference, and one thing Roon does that nothing else does as well.
What Roon Actually Is
Roon is a music library and playback application. You point it at your files, FLAC, DSF, M4A, whatever and it reads the tags, connects to MusicBrainz and AllMusic to pull in rich metadata, and presents everything in an interface that looks like a well-funded streaming service that also knows about your obscure 1974 Japanese pressing.
It runs as a server (the “Roon Core”) on a dedicated machine, a NAS, or a supported network streamer. Endpoints, the actual playback devices, connect to the Core over your network. A Roon-ready DAC, a Raspberry Pi running RoPieee, a compatible streamer, or an app on your phone can all be endpoints simultaneously. You can be playing different music in different rooms from the same library without any of the awkwardness that entails in most setups.
The interface is legitimately the best in this space and I’m picky with GUIs. Artist pages link to related artists, albums show personnel credits that actually go somewhere, you can follow chains of musicians and producers across your library for hours. For people who want to know that the pianist on this ECM record also played on three other records you own and two you don’t, Roon is unmatched.
It’s pretty expensive for a software music player and I hate subscriptions. It costs $14.99/month or $829.99 for a lifetime license. That’s not nothing, and I’ll come back to whether it’s worth it.
My Roon Dealbreaker: The Atmos Problem
Here’s the thing that doesn’t get a prominent mention in Roon’s marketing: Roon does not support Dolby Atmos bitstream passthrough. For me that’s a major dealbreaker as I primarily listen to new Atmos Blu-ray audio discs at this point. I just picked up the recently released Jeff Buckley Grace and it’s hard for me to go back to stereo after the immersion these new Atmos mixes offer.
Roon’s audio engine decodes everything to PCM before sending it to your endpoint. For FLAC, WAV, even DSD this is fine. For TrueHD Atmos, it means the Atmos object metadata gets stripped and your AVR receives multichannel PCM. Your overhead speakers sit there doing nothing. Your AVR displays PCM instead of Dolby Atmos. The file that Lossless Extract pulled intact from your disc, with all the spatial object data preserved, gets flattened on the way out.
This is the same fundamental problem as foobar2000. Different product, same architecture, same result.
Roon does support DTS-HD MA bitstreaming in some configurations, specifically via RAAT (Roon Advanced Audio Transport) to certain endpoints. The specifics depend on your endpoint hardware. But for TrueHD and Atmos, as of 2026, passthrough is simply not available. It’s been a feature request on Roon’s community forums since at least 2018. The thread has hundreds of votes and a Roon employee pops in occasionally to say it’s technically complex. It’s really not though. Kodi does it and it’s open source. It’s also been six-plus years. Maybe Roon needs a Claude Code subscription!
If your library is primarily stereo FLAC and DSD, this doesn’t matter. If you’ve spent time building an Atmos collection from Blu-ray discs like I have, it matters a lot.
What Roon Gets Right That Kodi Doesn’t
The interface is not comparable. Kodi’s music library interface was designed for a ten-foot TV display navigated with a remote, and it shows. It works. It handles albums, artist browsing, and search without trouble. It is not a beautiful piece of software (although it can look pretty good with the right theme), and it does not make you want to spend an hour just browsing your library.
Roon’s interface makes browsing your library an activity in itself. The metadata integration is deep enough that you’ll find yourself following links: this album to this producer to three other records you own in a way that doesn’t happen in Kodi. For someone with a large library built over years, that experience is worth something. I care more about listening.
Multi-room and multi-endpoint are genuinely easy in Roon. Want the same music playing in your listening room and your kitchen simultaneously? Grouped zones, synced playback, controlled from your phone. Kodi can sort of do this with some configuration but it’s not what it was designed for.
DSD playback. Roon handles native DSD to compatible DACs beautifully and is better than anything except foobar2000 with the right plugin setup. For a SACD-heavy library going to a DSD-capable DAC, Roon is the better choice. As I mentioned in the foobar post: Kodi converts DSD to PCM on the way out. Roon sends it native. If that matters to you, it matters. I can’t tell the difference between Kodi’s SACD to PCM at 176.4 and DSD though.
Roon Radio and discovery. Roon has a radio feature that plays music from your own library based on what you’re listening to, using its own recommendation engine trained on your collection. It’s surprisingly good and has led me to things in my own library I’d forgotten about. Kodi has playlists and plugins that can get you close, but nothing as elegant.

| DTS-HD MA passthrough | ⚠️ Some endpoints | ✅ Yes |

Who Should Use Roon
If your library is built around stereo FLAC, high-resolution PCM, and SACD rips going to a DSD-capable DAC, and Atmos is not part of your setup, Roon is genuinely the best software in this space. The interface alone is worth the subscription if you have a large library and you care about the listening experience being enjoyable to navigate. I have a friend with a four-figure speaker setup who uses Roon and he has no complaints, but he’s not running Atmos and is a stereo purist snob.
If you’re a serious two-channel listener with a good stereo DAC, Roon is probably what you should be using.
Who Should Use Kodi
If Atmos is why you’re here, if you’ve been ripping Blu-ray discs specifically to get lossless TrueHD Atmos into your ceiling speakers, Kodi is the only serious answer right now. There is no other free or affordable option that bitstreams TrueHD Atmos from a local file to an AVR.
Kodi on a Shield Pro connected via HDMI to an Atmos AVR is the most popular chain in the audiophile community for a reason. It works reliably, it handles M4A and MKA Atmos files correctly, and the setup guide covers everything you need to get there. The interface won’t make you want to browse your library for fun, but the Atmos light on your AVR will come on and your ceiling speakers will engage and that’s what you came here for.
Can You Run Both?
Yes, and this is what I’d suggest if you have a mixed library, with one caveat if you’re Shield-based. The Shield can act as a Roon endpoint but not a Roon Core, and it has audio quality limitations above 48kHz as an endpoint. For Roon to work properly you’d need a separate machine running the Core, a NUC, a Mac mini, or a NAS with enough horsepower. If your whole setup runs through a single Shield, running both is more friction than it’s worth. If you have a separate computer on the network already, it’s straightforward.
Roon handles the stereo and DSD material through a dedicated two-channel system or headphone rig. Kodi on the Shield handles Atmos and DTS-HD MA through the home theater setup. Both point at the same NAS share. You’re not duplicating files, just using different software for different use cases in different rooms.
That’s the honest state of things in 2026. Roon could fix the Atmos problem if they prioritized it. The feature request has been open long enough that at this point it feels more like a product decision than a technical one. Until they do, the answer for people who care about both DSD and Atmos is two players. Personally I think overall Kodi is still the better choice.
All the formats mentioned here — TrueHD Atmos, DTS-HD MA, DSD, FLAC — can be extracted from disc with Lossless Extract, tagged correctly, and pointed at whichever player fits your chain. The formats post covers which output format to use for each destination if you want to get into that.
