The buying question
Do you need Sony-documented Ultra HD Blu-ray and 4K/HDR setup, or does a Full HD player with a connection route that fits your receiver cover the job?
The UBP-X700U adds documented Ultra HD Blu-ray playback and a second audio-only HDMI route, with specific 4K display, cable and receiver setup conditions. The BDP-S1700U is documented for Full HD and common Blu-ray/DVD/CD media, with HDMI and coaxial receiver routes.
Quick verdict
Choose Sony UBP-X700U if
- You want UHD Blu-ray playback and have a compatible 4K TV, suitable 18 Gbps HDMI cable and the needed TV format setting.
- Your 4K TV is paired with a non-4K receiver that has HDMI IN, and you want the manual's HDMI1-to-TV / HDMI2-to-receiver routing option.
Choose Sony BDP-S1700U if
- Full HD and the BDP-S1700U manual's listed Blu-ray/DVD/CD media fit your library.
- Your receiver can use the BDP-S1700U's documented HDMI-through-receiver route or HDMI-to-TV plus coaxial-audio route.
When the recommendation changes
- The disc formats you own, TV's supported HDMI format, available cables, or receiver inputs change which documented route fits.
The differences that matter
Disc Library And Display Format Fit
What this changes: Choose the UBP-X700U if you want a positively documented UHD Blu-ray playback path and can meet its TV, cable and signal-format conditions. If your library is Full HD and uses media listed in the S1700U manual, the S1700U can fit that stated need. The reviewed Sony sources leave S1700U UHD playback unconfirmed; check with Sony if UHD support is a requirement.[2, 3, 4]
Existing Receiver Video Audio Routing
Sony UBP-X700U
The UBP-X700U has HDMI OUT 1 for video/audio, HDMI OUT 2 for audio only, and coaxial digital audio. Sony shows HDMI OUT 1 through a 4K receiver; for a non-4K receiver with HDMI IN, it shows HDMI OUT 1 directly to the TV and HDMI OUT 2 to the receiver, with HDMI Audio Output set to HDMI2 or Auto; for a receiver without HDMI IN, it shows HDMI OUT 1 to the TV and coaxial audio to the receiver.[1, 2]
What this changes: If you have a 4K TV and a non-4K receiver with HDMI IN, the UBP-X700U manual documents a split-output path that sends video to the TV and audio to the receiver. If a receiver's HDMI route or the HDMI-to-TV/coax-to-receiver option fits your Full HD setup, the BDP-S1700U manual documents those paths. Check the receiver's own inputs and supported formats; Sony's examples do not guarantee every receiver combination.[2, 4]
Best for your routine
A buyer who wants to play Ultra HD Blu-ray discs on a compatible 4K display
Best fit: Sony UBP-X700U
Based on listed features, not comparative testing.
Sony documents UHD Blu-ray playback for the UBP-X700U and specifies the display, cable and TV-setting conditions, so it fits a buyer who requires that documented UHD path.
A buyer with a Full HD display and a library covered by the BDP-S1700U manual's Blu-ray/DVD/CD list
Best fit: Sony BDP-S1700U
Based on listed features, not comparative testing.
Sony documents Full HD 1080p and BD/DVD/CD media for the BDP-S1700U. For a buyer whose display and library need these listed formats, the S1700U's documented capabilities fit the stated requirement; UHD capability is not needed for this scenario.
Keeping a 4K TV and a non-4K HDMI receiver in the same player setup
Best fit: Sony UBP-X700U
Based on listed features, not comparative testing.
The UBP-X700U manual shows HDMI OUT 1 to the TV and HDMI OUT 2 audio-only to a non-4K receiver with HDMI IN. Connected-device format support and the HDMI2/Auto setting still matter.
Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
The UBP-X700U's documented UHD playback and second audio-only HDMI route matter when they fit your setup; compare current exact-variant offers to decide what those features are worth to you.
The short observation window does not support a price-timing recommendation.
Limitations
- Sony's two manuals illustrate example connections; check your receiver's inputs and supported signal/audio formats before buying.
- Exact retail-box cable contents were not established by the official manuals and product pages checked here.
- This is a published-feature and setup comparison, not a measurement of picture quality, sound quality, reliability or playback performance.
Questions shoppers ask
What does Sony require for UHD Blu-ray playback on the UBP-X700U?
Sony's instructions call for a compatible 4K TV, a Premium High Speed HDMI cable supporting 18 Gbps and the TV's appropriate HDMI format setting. Connected devices in the signal chain also need to support the format you want to watch.
Can the UBP-X700U work with a non-4K receiver and a 4K TV?
Sony shows HDMI OUT 1 connected directly to the TV for video and HDMI OUT 2 connected to a non-4K receiver with HDMI IN for audio. The manual says to select HDMI2 or Auto for HDMI Audio Output on that route. The TV, cable and other connected devices still need to support the format you want to watch.
