Four hundred and thirty millimeters, which is the whole idea
Designed to fit naturally into a traditional home stereo stack… a 430 mm / 16.9-inch-wide profile, an aluminum front panel, and a metal housing.
Hi-fi separates — amplifiers, CD players, tuners — have been built to roughly 16.9 to 17.3 in (430 to 440 mm) for decades, so a stack of them lines up.
Put a 6.69 in (170 mm) plastic box on top of a 17.3 in (440 mm) amplifier and it reads as an accessory. Which is exactly what every other radio on this shelf is: the WR-03M is 6.69 in (170 mm) wide, the Grace Link 191, the WR-336M 185, the WR-393 249, the WR-860 310.
At 5.5 lb (2.5 kg) with a metal case this is also the heaviest thing here, and the mass is part of the same argument — a component-sized box that weighs nothing reads as hollow.
So this is the only product on the shelf that will look right in a rack. On a device that will sit in a living room for a decade, that is a real reason.
Four outputs, which is the fullest set here
Optical (Toslink), coaxial S/PDIF, or stereo RCA outputs, and… the front 3.5 mm headphone jack.
Each has a use, and having all four means matching whatever you own.
Stereo RCA is analog at a fixed level: this tuner’s converter does the work, and it connects to any amplifier ever made.
Optical passes the digital stream untouched, so a better converter downstream does the job — and being light rather than electricity, it is immune to interference and breaks any earth loop.
Coaxial S/PDIF does the same over copper, and generally carries higher sample rates more reliably than optical.
And the front headphone jack is private listening with the amplifier off entirely.
On this shelf: the WR-03M publishes line-out and optical, the Grace Link “analog and pure digital” without saying which, the WR-860 a line out, the WR-336M a headphone jack — and six products publish none, including the $899 Audiolab.
External Wi-Fi and Bluetooth antennas support wireless reception.
The reasoning follows directly from the construction. A metal housing screens radio signals in both directions: good for keeping interference out of the audio circuits, bad for letting Wi-Fi in.
An internal antenna inside an aluminum and steel box, pushed into the middle of a stack of other metal boxes, receives poorly. An external whip can be raised above the stack and aimed.
The WR-393 at $139.99 publishes an “external WiFi antenna socket” for the same reason.
And both offer the complete answer. This publishes “wired Ethernet (RJ45)” with WPS support, and for a component that never moves, wired is simply the right choice — it removes congestion, distance and interference at once.
Custom stream URLs, which make the station count beside the point
Store up to 150 custom presets or add custom station stream URLs through your web browser.
Every internet radio depends on a directory, and the claims differ: Grace says 100,000, this says “over 30,000”, the other Ocean radios say “thousands” — all Ocean models through Skytune.
None of that tells you whether your station is listed.
A custom URL does: paste in the stream address and any station with a public feed works. Only this and the WR-393 explicitly publish it.
And doing it in a browser is what makes 150 presets usable — a flat list navigated with a front dial is not.
A front dial, and a 2.4 inch screen
Navigate menus on the crisp 2.4-inch color display using the included full-function IR remote or front control dial.
A dial is the right control for a tuner: one hand, no modes, and it works from standing. The bullet’s framing is correct too — “Enjoy direct, hassle-free control without relying on a phone” — which is the opposite of the WiiM Mini and iEAST Olio, both of which are app-only.
The screen is the reservation. 2.4 inches on a 16.9 in (430 mm) front panel is small, and it is the smallest display among the larger radios here: the WR-393 has 3.5, the WR-03M 3.2, the Grace Link 2.8.
Front-panel USB is the other sensible placement decision — a stick in the front rather than reaching behind a rack.
What is not published
No network casting. No Chromecast, no AirPlay 2, no Spotify Connect — so a streaming service reaches it only over Bluetooth 5.0, with the phone decoding and transmitting and needing to stay in range.
That is the structural divide on this shelf, and at this price it is the thing to weigh: the Grace Link at the same $179.99 has Chromecast built-in and Spotify Connect, so your phone is only a remote — but it is 7.52 in (191 mm) wide and will not sit in a stack.
No resolution figure. The Grace Link at $179.99 publishes 24 bit / 192 kHz; so do the WiiM Mini and iEAST Olio. No Ocean Digital radio publishes any.
No equalizer, where both Grace units publish a five band one and the WR-03M publishes “EQ sound modes”.
No alarms or timers, which every other Ocean radio here has — and which is consistent with its positioning as a component rather than a bedside radio.
No box contents, where the Grace Link publishes its remote “and batteries”.
2,495 g and 430 × 243 × 48 mm are published, and at 48 mm tall it is the slimmest of the full-size boxes — which again is correct for a stack.
