TUNERSYS WS161: When an Internet Radio Finally Grew Its Own Voice
I'm done.
For the last few years, my little basement listening nook has turned into a graveyard of good intentions. A drawer full of Bluetooth dongles that squashed Nina Simone's upper register into fizzy digital confetti. A Sonos Connect that decided to drop off the network every time the microwave fired up. And don't get me started on the multi-room apps that need more updates than my tax software. I didn't want a "smart home ecosystem." I wanted a modern tuner I could reach out and touch — something that would feed a clean, no-nonsense Wi-Fi stream straight into a pair of vintage passive monitors without a rat's nest of outboard gear in between.
Running a small living space art project (whatarter) here in Brooklyn, I'm always an absolute crank about how gear looks on a shelf—it has to look like fine furniture and sound like heaven. I stumbled upon this unit online, and figuring the return policy would protect me if it was junk, I pulled the trigger.
In plain English, I wanted my Marantz 2270 back, but for the age of internet radio. I just never expected anyone to actually build it.
Three weeks ago, a carton arrived from an outfit called TUNERSYS. I unboxed it, wired it up, and powered it on. It now sits on my equipment rack, right where the 2270 used to live, glowing a soft amber. I figure it's time to talk.
What It Actually Is
The WS161 is something I've been scouring spec sheets for since the Obama administration, and I hadn't seen it until now: a complete, high-end Skytune internet radio tuner with a built-in hi-fi amplifier. That description sounds deceptively plain, but anyone who's waded through the current streaming landscape will understand why it's rare. There are plenty of bare Skytune streamer boards, and there are countless little Class-D chip-amps dressed up as lifestyle products. But nobody, until now, had the good sense to mate an honest amplifier stage to a fully fleshed-out Skytune front end inside one well-damped chassis, and then give you a clean set of speaker terminals that mean business. That, my friends, is the killer feature. It's the reason my credit card came out.
Yes, the amp is Class D. A Texas Instruments TPA3611.
I know some of the old bones around here still frown at the letters "Class D." I did too, initially. But the way this TPA3611 conducts itself inside the WS161 has made my prejudices look silly. This isn't one of those cheap, efficiency-at-all-costs implementations that sacrifices any semblance of musicality. Driving my 15-ohm Rogers LS3/5a — a load that has humbled far more expensive amplifiers — the little Rogers woke up. Piano decay hung in the air. Stand-up bass had real wooden body, not just thump. When I switched over to my equally ancient Yamaha NS-10M Studios, the midrange was as ruthlessly honest as ever, and even pushed to uncomfortably loud levels, the amp never sounded like it was running out of breath. The power supply filtering inside clearly does its job well. TUNERSYS chose this amplifier for a very straightforward reason: one box, no fuss. And you have to admit, there's a kind of moral superiority in being able to pour a glass of bourbon at midnight, flip a switch, and let music fill the room with zero additional drama.
But the feature that truly cements this machine's place on my shelf is on the back panel: a pair of fixed-level RCA outputs, plus a 3.5mm headphone jack.
Build Quality: The Kind of Metal You Can Knock On
The front panel is a thick slab of brushed silver aluminum — not some plastic facsimile stamped with a metallic-looking sticker, but actual metal with a grain you can feel under your fingernail. The main chassis follows suit: heavy-gauge aluminum all around, the kind that doesn't ring when you rap it with a knuckle. It weighs in at a reassuring 2.5 kilograms, which for a half-rack-width box this size tells you there's real iron and copper inside, not just air. It feels like a piece of gear from the era when manufacturers still believed you'd be using their products in twenty years.
Controls: One Knob to Rule Them All
The user interface on the WS161 is a study in elegant minimalism. On the unit itself, you get three touch-sensitive keys on the front panel, but the star of the show is that single, large multifunction knob. And what a knob it is — solid aluminum, beautifully damped, with the kind of weighted flywheel resistance that reminds me of tuning an old Accuphase. It does everything. Spin it left or right to jog the cursor quickly through station lists or settings menus. Push it straight down and it's your Enter, your OK, your confirmation. Give it a twist while music is playing, and it becomes a volume control, smooth and precise. It's one of those rare interfaces where form and function lock together so naturally that after a day or two, you stop thinking about it entirely. Your hand just knows where to go.
The remote control is a simple rubber-button affair — nothing fancy, but perfectly functional. All the key operations are within thumb's reach, and the buttons have a positive, tactile click. It's not the machined-aluminum showpiece that the front panel knob is, but it does the job without fuss, and it'll survive being dropped between the couch cushions.
Presets, Alarm, and Sleep: Little Things That Matter
Here's where the WS161 quietly shows it understands how real people listen. You get 99 preset slots for your favorite stations — not the stingy dozen or so that some manufacturers dole out — which means you can actually organize your listening. I've got Classic Hits Radio on preset 1, FIP Paris on 2, RTÉ Lyric on 3, a Scandinavian free-jazz stream on 7, a Tokyo J-AOR community station on 12, and so on. One press and you're there.
But the feature that genuinely surprised me is the music alarm. You can set the WS161 to wake you up on specific days of the week at a specific time, and it'll fire up whichever of your 99 presets you choose. There's something almost decadent about being gently pulled from sleep by a Celtic harp broadcast from County Clare, piped through your own LS3/5a at 7:15 on a Sunday morning. It's the kind of civilized touch that makes the machine feel less like a gadget and more like a household companion.
On the flip side, there's a sleep timer with settings for 15, 30, 45, 60, or 90 minutes. I've been using it almost every night. Set it to 60, let RTÉ Lyric play, and the WS161 quietly powers itself down while I'm already somewhere between waking and dreaming.
A Note on Speaker Connections (Because Someone Will Ask)
Around back, you get four speaker terminals — left positive and negative, right positive and negative — not eight, not a full surround array. Just good old-fashioned stereo. The WS161 actually comes in two versions here, depending on your preference: one with sturdy push-clip terminals that grab bare wire like a bulldog, and one with proper banana-plug binding posts. Mine is the banana-post version, and I'm happy to report they're solid, gold-plated, and accept the kind of spades and bananas you actually have lying around in your cable bin. If you're the type who still uses lamp cord stripped with a pocket knife, the push-clip model has your name on it. Either way, the connection feels deliberate, not like an afterthought.
Power Supply: The Upgrade an Old Crank Can't Resist
The WS161 ships with a standard 24V/3.5A switching power adapter. It's perfectly adequate — the unit fires up, streams flawlessly, and makes music without any obvious nasties. But I've been fooling around with hi-fi long enough to know that clean DC power is never a bad idea, especially when a manufacturer offers an upgrade path without forcing my hand.
TUNERSYS makes an optional linear power supply specifically for this unit, and after a week of listening with the stock brick, I ordered it. The thing is a tank: a sealed, potted toroidal transformer inside a solid aluminum chassis, putting out 18V at a beefy 6.5A. It uses Toshiba power transistors, Rubycon low-ESR capacitors, and a CLC filter with a red ring inductor and four chemical filter caps to knock down high-frequency ripple. No fan, just passive cooling through dual vent rows on top. It's built like a piece of lab equipment, not a wall wart.
The difference it made was not night-and-day in the sense of a complete tonal overhaul — the WS161 already sounded good — but it was the kind of change that, once you hear it, you can't unhear it. With the linear supply in place, the background became even blacker. Sounds emerged from a deeper void. On familiar piano recordings, the initial attack of a hammer hitting string felt faster and cleaner, and reverb tails decayed more naturally into silence. The slight grain I'd unconsciously attributed to the Class-D amplifier? Largely gone. I suspect a good chunk of what I was hearing with the stock adapter was high-frequency noise from the switching supply subtly hardening the upper mids. The linear supply scrubbed that away. It's the same sensation as upgrading a phono preamp's wall wart — the music doesn't necessarily change its fundamental character, but it breathes easier. Everything relaxes.
Now, I'm not saying you need to buy the linear supply on day one. The WS161 is perfectly enjoyable out of the box. But if you're the type who keeps your gear for a decade and obsesses over the last few percent of performance, this upgrade is genuine, audible, and refreshingly free of snake oil.
Two Lives, One Chassis
The WS161 has lived two completely different lives under my roof.
The first week, I used it to drive the Rogers directly. Speaker cables locked into the binding posts, and the machine became a single, pure system: radio tuner plus integrated amplifier. As I spun that big multifunction knob, I was suddenly transported back to the late Seventies. Except instead of straining to catch distant college stations buried in the FM noise floor, I was watching the little green LCD quietly announce, "FIP Paris, AAC, 256kbps." A jazz piano trio I didn't recognize drifted out of the LS3/5a against a backdrop of absolute, needle-drop silence. The sensation was uncanny. The romance of long-distance radio reception had been preserved by the Skytune engine, but the ionospheric hiss and signal fading were gone, replaced by clean Wi-Fi packets. It recreated the magic of DXing, with the signal-to-noise ratio of a modern digital source.
The second week, I pulled the RCA cables and fed the WS161 into my much-repaired, long-suffering Dynaco ST-70 tube amp. In this configuration, the WS161 retreated into the role of a pure "internet tuner head." It no longer drove anything, no longer imparted its own character — it simply plucked the one station you wanted from a directory of thirty thousand, decoded the stream, and handed it over as a clean line-level signal to my old friend. What I heard was purer than many dedicated hi-fi streamers I've auditioned. No DSP, no room correction, no multi-room sync latency calculations. Just a faithful messenger, refusing to flatter or obscure.
Which brings me to a crucial fact I need to lay on the table.
Sound Quality Is Up to the Station, Not the WS161
That little 2-inch green-backlit LCD screen is probably the most honest component on the entire machine. It shows you all its cards.
When I tuned into Classic Hits Radio and Billy Joel was belting out Tell Her About It, the screen read: AAC, 220kbps, 44100Hz, 2 ch. The soundstage opened up wide, the brass had real bite without hardness, and the electric piano notes were distinct and round. But then I'd spin the knob half a turn to an oldies cover station streaming at 128kbps MP3, and suddenly the top end sounded like it was wrapped in gauze. That's the reality of internet radio. The WS161 won't upscale a lousy source into pseudo-Hi-Res. It faithfully hands you exactly what the station is broadcasting, presented in the best possible light. That little screen blinking the bitrate and format is the machine's quiet confession of honesty.
And the real magic of the Skytune platform is that sometimes, you stumble upon stations that genuinely care about their streaming quality. When Ireland's RTÉ Lyric FM pours into the room at a warm 256kbps AAC, a Celtic harp solo can make the air in front of the speakers feel as if it's vibrating with nylon string friction. In those moments, this isn't any kind of retro-nostalgia substitute. It's genuine high-fidelity radio.
An Old Crank's Final Thought
I won't pretend the WS161 is for everyone. If you require Roon Ready, a touchscreen that scrolls through album art, or the ability to push music to every room from your phone, look elsewhere. But if, like me, you've had your patience worn down to a nub by Bluetooth compression artifacts and app ecosystems that feel more neurotic than functional — if you just want a single, dedicated box sitting on your shelf that can either drive your beloved old monitor speakers directly, or feed a clean line-level signal into the vintage amplifier you've been babying for half your life — then this machine has soul.
It's not a mystical artifact. It's an honest, no-nonsense piece of gear. The thick silver aluminum front panel and heavy-gauge chassis give it the gravity of vintage equipment. That big multifunction knob is a tactile joy — spin to browse, push to select, twist for volume, all with one satisfying motion. Three touch keys keep the front panel clean. The rubber-button remote is unpretentious and does exactly what it needs to. You get 99 preset slots, a music alarm that wakes you with your favorite station on the days you choose, and a sleep timer that tucks the music in after 15, 30, 45, 60, or 90 minutes. The standard power adapter gets you up and running just fine, but if the upgrade itch strikes, that linear supply turns a great little tuner into something genuinely refined. The WS161 uses Wi-Fi to place the world's radio stations at your fingertips. The built-in amplifier is there for your convenience, not as a compromise, and those RCA outputs are an act of respect for the old soldiers already in your rack.
Tonight, I pressed preset number five. A Celtic harp from County Clare, Ireland, once again drifted into the room through the LS3/5a, completely grain-free, steady as granite. I set the sleep timer to 60 minutes, switched off my phone, killed the air conditioning, and just sat there under the lamp for a long while.
When was the last time I listened to the radio this purely?
I can't quite remember. Probably before the internet existed.
