Kaleidescape Strato V Movie Player review: 4K Blu-ray video and audio quality minus the discs
KALEIDESCAPE STRATO V: One-minute review
The Kaleidescape Strato V is the latest Movie Player from Kaleidescape, and it represents a definite shift for the company. Kaleidescape is synonymous with a premium movie experience at home, offering a proprietary ecosystem based around its own hardware and servers. While no one questions the quality of Kaleidescape’s products, the price of admission has been steep and the lack of Dolby Vision support has been a glaring omission given the brand’s pursuit of high-end video and audio performance.
The new Kaleidescape Strato V addresses both of these issues by offering Dolby Vision support and lowering the cost of entry. To achieve this, the Strato V integrates a 960GB solid-state hard drive, and while that means it can only store around ten 4K movies downloaded from the company’s Movie Store at any one time, at least it combines the movie player and movie server into a single, more affordable device that's an excellent alternative to the best 4k Blu-ray players.
With Kaleidescape, you can immediately access a huge library of films, TV shows, and concert videos, with new titles often available months before any disc release. The picture and sound quality are exceptional, with stunning 4K HDR10 and Dolby Vision images and full lossless audio that includes Dolby Atmos and DTS:X – something you don’t get from the best streaming services, which only provide compressed soundtracks. The result is a performance that’s at least equal to a disc but without taking up all your shelf space. So if you want convenience without any compromise look no further than the Strato V.
KALEIDESCAPE STRATO V review: Price & release
- Price: $3,995 / £5,379
- Release date: September 2024
The Kaleidescape Strato V is available now through registered dealers and online sellers like Best Buy in the US and retails for $3,995 / £5,379. While this certainly isn’t cheap it’s definitely more affordable than the alternative of buying the Kaleidescape Strato C Movie Player. The latter costs about the same but doesn’t support Dolby Vision and requires you to buy one of Kaleidescape’s Terra Prime servers, which are very pricey. Of course, if you want to expand the storage of the Strato V you can add a Terra Prime server, although the extra cost does rather defeat the whole point of buying one.

KALEIDESCAPE STRATO V review: Design
- Great build quality
- Kaleidescape remote app
- Control over Ethernet
The Kaleidescape Strato V certainly looks like a premium product with a sleek, stylish and very well-made cabinet that uses a combination of a 3mm-thick black anodised aluminium chassis combined with a 3mm-thick black glass front with an illuminated Kaleidescape logo. The unit is silent in operation and includes a 960GB solid-state drive, along with a powerful system-on-chip (SoC).
The unit is only 20cm wide, which might disappoint those who like their AV equipment full width, but there’s an optional faceplate for mounting in an equipment rack. There’s also a dual faceplate for use with a compact Terra Prime server, along with a wall bracket for mounting behind a TV.
The connectivity is at the rear, with a gold-plated HDMI 2.1 output, a coaxial digital audio output using a gold-plated RCA phono connector, and an optical digital output. There’s also a gigabit Ethernet port, a USB 3.0 port, an IR input, a service port, and a 12V input for the included power adapter brick. There is no Wi-Fi connectivity, so you will need a wired Ethernet connection for downloading movies, accessing the web interface, updating firmware and using the control app.
The included remote is small and simple but gets the job done. There’s no backlight, which can be annoying in a pitch-black home cinema, but given Kaleidescape’s target market, chances are you’ll be using a third-party control system over Ethernet like Crestron, AMX, Savant or Control4. There’s also the Kaleidescape app (iOS or Android) which makes an effective controller, providing an alternative to the remote with its handy swipe function and access to the Kaleidescape Movie Store.

KALEIDESCAPE STRATO V review: Features
- Scalable storage options
- Highest quality video
- Fully lossless audio
The Kaleidescape Strato V’s primary function is as a high-end movie player that offers the best video and audio compared to any device on the market. To achieve this it supports every resolution up to 4K (3840 x 2160), and frame rates up to 60p. It also supports HDR10 and Dolby Vision high dynamic range, plus lossless audio up to and including Dolby Atmos and DTS:X.
Crucially, it isn’t limited to certain file sizes as with a 4K disc, nor is it restricted to lower bit rates like streaming services – supporting file sizes of over 100GB and speeds up to 100Mbps. As a result, when you buy or rent movies, TV shows or concerts from the Kaleidescape Movie Store you’re guaranteed the best picture and sound possible from a home entertainment product.
The Strato V is primarily designed to operate as a standalone unit, which is why it has a built-in solid-state hard drive. The downside is that the number of movies you can store at any one time is limited to around 10, and if you want to watch something else you have to download it. Once you purchase a title from the Kaleidescape Movie Store it remains accessible in your collection for download, even if it isn’t stored locally on the Strato V.
If you would rather store your entire collection on a drive for instant access you can connect to one of Kaleidescape’s Terra Prime servers. While doing so is obviously more expensive, and the built-in SSD is no longer available, the process is simple and won’t affect the Strato V’s performance in any way. It’s great to have the option to scale up the storage, even if you never actually need to.

KALEIDESCAPE STRATO V review: Setup
- Web-based interface
- Selectable aspect ratios
- Cataloging your discs
The Kaleidescape Strato V is incredibly easy to set up, and all you need to do is plug in the power brick, attach an Ethernet cable and connect to your display, or in my case an AV processor. Kaleidescape even includes a THX Certified HDMI cable, which is a nice touch. Once powered up, just follow the onscreen instructions and you’ll be up and running in no time.
The initial options allow you to set up the Strato V as a standalone player, configure it as a new system with a Terra movie server, or add it as a new zone to an existing Kaleidescape system. When set up as a standalone player it operates independently, only playing movies stored locally on its internal drive, and can’t be grouped with other Strato V units for additional storage.
After I selected standalone mode, the activation page appeared. You then either enter your email address if you already have a Kaleidescape account or create a new one. Once you’ve entered your email address you’ll receive a confirmation email to activate the player. You’ll obviously need to add your credit card details as well for making purchases from the Kaleidescape Movie Store.
The web-based interface offers access to all of the Strato V’s setup options and is my preferred choice for the initial installation, although once completed the remote is fine for accessing your movies on the player (Ready to Play), and navigating the Kaleidescape Movie Store and general settings.
In terms of the initial settings you can leave most at their defaults because the Strato V will read the EDID from your display, receiver or processor and optimise accordingly. The one area you may need to adjust manually is the aspect ratio, especially if like me you use a 2.35:1 projector screen. This feature works brilliantly, not only formatting the screens and menus for the wider aspect ratio, but also automatically rescaling 1.85:1 content within the ‘Scope ratio screen.
The main reason for buying a Strato V is access to the Kaleidescape Movie Store, and here your experience will really depend on on where you live. In the US the choice is huge and new films are added months before they’re released on disc, whereas elsewhere the choice isn’t as impressive, and films take longer to be added. I appreciate that studio agreements will differ from territory to territory, but given the store is the main feature it’s a bit frustrating if you live outside the States.
One final feature that Kaleidescape offers is the option to catalog your physical Blu-ray and DVD collections into a digital format. You’ll need to connect an external disc drive via USB, but once connected, the Strato V enters Recognition Mode. Insert a disc into the drive, and the Strato begins cataloging it. The process only takes a few seconds, and you can then see the title in the Store under Digital Offers – sometimes with a discount for the digital version.
KALEIDESCAPE STRATO V review: Performance
- Well-designed and intuitive interface
- Exceptional picture and sound quality
- Excellent upscaling of lower resolutions
The Kaleidescape Strato V is a rock-solid media player thanks to its intuitive user interface, and is also very responsive in operation. The Ready to Play page has titles from the Store along the top, a second layer showing the unwatched titles currently on the internal drive, followed by a layer of paused movies, then the played movies, and finally any movies you’ve marked as favourites.
Unlike the Strato C, the Strato V doesn’t show you all the films you’ve bought on the home page, only those on the internal drive. If you want to see the complete collection you’ll need to go to your account on the Movie Store, but this keeps things neat and tidy. The system automatically deletes the oldest played content to free up space, unless you mark a title as a favourite.
When you click on a title you get information about it, along with options to play, pause or choose a specific scene. When something is playing you can also press the up button on the remote and see additional information such as audio options and subtitles. The entire process is completely seamless, and I never had any issues with playing, pausing or stopping movies. It’s also worth pointing out that the Strato V runs completely silent and cool in operation.
The process of buying titles from the Movie Store couldn’t be easier, and you can access it via the Kaleidescape website, through the player’s interface or even using the app. There are thousands of titles available for purchase or rental, many of which haven’t even been released on 4K disc yet.
I found deleting existing films off the internal drive and downloading new ones onto it to be straightforward. If you decide to rent rather than purchase a title, it will remain on your system for 30 days, and once you begin watching it there’s a 48-hour window. If you like the film and decide to buy it within the 30-day rental period, half the rental price is credited towards the purchase.
The speed of download will depend on your internet connection – if you’re lucky enough to have gigabit speeds you can download movies in around 10 to 15 minutes. Unfortunately, I live in the countryside and only have speeds of 50Mbps, so it took about two hours to download a movie.
When you buy a title it might offer 4K Dolby Vision and 4K HDR10 versions, but even if your display doesn’t support Dolby Vision you still download the former. The Strato V will automatically output whatever your display is capable of handling, while the 4K HDR10 version is only intended for the Strato C because that player doesn’t support Dolby Vision at all.
Kaleidescape’s use of larger file sizes and higher bit rates results in stunning images that are at least as good as the equivalent 4K Ultra HD disc, if not better. I watched a number titles, including Top Gun: Maverick, Dune Part 2, and Furiosa, and the picture quality is simply stunning. The 4K images are sharp and detailed, the HDR10 or Dolby Vision is delivered precisely, and the overall presentation is free of any compression artefacts or other issues.
While you can obviously watch movies on streamers, or via VOD services like iTunes and Prime Video, Kaleidescape offers a quantum leap in quality. In fact, the larger file sizes mean it can even surpass 4K Blu-rays at times. A good example is Once Upon a Time in the West, which is a three-hour movie that gets crammed onto a 66GB 4K Blu-ray disc. Kaleidescape’s file is significantly larger, providing more space and a higher bit rate, which results in a better-defined image when directly comparing this film on both formats.
The audio is equally impressive, with full lossless support for Dolby Atmos and DTS:X. While streaming services may offer Atmos, it is usually delivered via lossy Dolby Digital Plus, but with Kaleidescape you’re enjoying the same full lossless experience you get with Blu-rays. Hans Zimmer Live in Prague sounds amazing in Atmos, while Harry Potter and the Prisoner of Azkaban benefits from a DTS:X soundtrack that really brings the wizarding world to life. The scene where the dementors search the Hogwarts Express is doubly scary thanks to the genuine scale and really deep bass.
While I expected the 4K images to look superb, I was equally impressed by the quality of the Strato V’s upscaling. When watching lower-resolution content the picture is clean and well-defined, with no obvious scaling artefacts. The same is true when the player automatically re-scales 1.85:1 content within the 2.35:1 aspect ratio – the process is seamless and the results are free of any scaling artefacts.
- Performance score: 5/5
KALEIDESCAPE STRATO V review: Value
- It’s a significant investment
- There’s no direct competitor
The idea of value for money is always relative, and there’s no denying the Kaleidescape Strato V represents a significant investment. However, once purchased the ability to buy new movies months before they arrive on 4K disc in quality that’s at least as good, if not better, and without taking up shelf space is very appealing. This is especially true if you live in the United States, where the Movie Store library is genuinely impressive.
If on the other hand you’re the kind of person who prefers owning physical media, just to be on the safe side, and you don’t mind waiting for the disc to come out, then you could simply buy a media player and storage, rip your own discs and create a custom server for significantly less. The beauty of Kaleidescape’s unique ecosystem is that they do everything for you, so all you have to do is sit back and enjoy your favourite movies.

KALEIDESCAPE STRATO V review: Should I buy it?
Buy it if…
You want the best video and audio quality:
The larger file sizes offered by Kaleidescape, along with bit rates up to 100Mbps, ensure that 4K and HDR10/Dolby Vision performance is the best of any device on the market.
You want a slick and intuitive user interface: The Strato V’s intuitive user interface and high-powered processing ensure that downloading and watching content is a seamless, responsive and enjoyable experience.
You want early access to the latest movies: In the US in particular the Movie Store offers films months before they are released on UHD disc, and there are even 4K titles available that aren’t currently on physical media.View Deal
Don't buy it if…
You want to collect physical media: Kaleidescape’s system is based on a download model with titles accessed from an online account and stored on built-in drives. If you prefer physically owning content, discs are still your best bet.
You want to rip your disc collection: The cataloguing feature aside, the Strato V is designed to access Kaleidescape’s Movie Store and download content. if you want to rip discs you’re better off buying a media player and storage.
You want a streaming service: This is not a subscription streaming service like Netflix. Instead, you buy titles as very large files that, depending on your internet, can take a long time to download, but the picture and sound quality is significantly better.View Deal
How I tested the KALEIDESCAPE STRATO V
- Reviewed in a dedicated home cinema
- Video evaluated using 4K, HDR10 and Dolby Vision
- Audio evaluated using Dolby Atmos and DTS:X
I tested the Kaleidescape Strato V in my reference home cinema where the video is handled by a JVC DLA-NZ900 projector, and the audio is configured in a 9.4.6-channel configuration using a Trinnov Altitude16 AV processor and 16-channel power amplifier.
I extensively tested 4K and HDR10 video, along with Dolby Atmos and DTS:X lossless spatial audio in the home cinema, although for completeness I also used an LG G4 OLED TV in my living room to test the Kaleidescape Strato V’s Dolby Vision capabilities.
Kaleidescape was kind enough to include a number of films pre-loaded, as well as more in the account, along with a credit for additional purchases and rentals. This provided me with an opportunity to test every aspect of the store and overall ecosystem.
