The Premium Price
A Kaleidescape system is very expensive compared to a UHD Blu-ray player and streaming boxes like a 4K Apple TV. You are paying a premium for the highest quality. Strato S costs about as much as a nice 4K UHD projector. I personally think that it is worth the premium to have access to 2-3 times amount of 4K content, vs. UHD disc.
For those of us who “work for a living”, but care about picture (and audio) quality, the only real potential “deal-breaker” problem with the Strato S, is the price. If you are comfortable adding a $6,000 solution to your home theater/cave/living room system, from a pricing standpoint, you will be hard pressed to come up with a good reason to not have one!
Waiting to View
You will also have to get used to the idea giving up impulsive viewing with it. You can’t just say, “Gee, I want to watch the Princess Bride, NOW!” (unless you previously downloaded it, which is actually convenient if you pre-order new releases that can be watched at the start of the day they are released for home entertainment). While you can download new content in the background Kaleidescape discourages it.
If you start watching previously downloaded content during a download, the system may pause or slow the download process to ensure playback quality. The Kaleidescape Strato S, downloads fastest when you set it up and turn it off.
To deliver the highest quality content, the file size dwarfs that of streaming, so depending on your internet speed, you will need to wait at least an hour for most content to download before viewing. With Gbit internet connection, though you can download most movies in 4K, I am told in less than 10 minutes. I averaged a bit more (around 1 hour). Hey, by my take, that is a small price to pay!
