Updated WiiM Ultra and Amp Ultra Roadmaps Are Here

We just published an updated roadmap for the WiiM Ultra and the WiiM Amp Ultra, and we’ll be updating some other roadmaps soon. You can see the full details on our Help Center (Ultra| Amp Ultra), but here are some highlights and a quick look at where we're headed.

What This Roadmap Represents​

This is a transparent look at what we're actively building, what we're exploring, and what we've recently shipped. Some of these features will land exactly as described. Others might evolve as we work through technical realities and a few might not make it at all. You’ll also notice that there are no timelines, development is a long process and priorities shift throughout the year, so we’re not going to commit to specific timing right now.

We're sharing this openly because your feedback directly shapes our priorities. We watch all the forum conversations, app surveys, and feature requests you share, and use it all to feed into this. So check it out, and we hope there’s something in here you love the idea of!

These roadmaps focus on the Ultra and Amp Ultra first. They're our flagship devices with the hardware to support more advanced features. Where it makes sense and where it's technically feasible, we'll bring capabilities to other products in the lineup. Some features will be Ultra-specific by necessity.

What's Next​

Display & Interface Upgrades

Input-specific screen layouts that remember your preferences and automatically switch based on active input. Black background mode for album art that blends seamlessly with the bezel. Standby and clock options including permanent clock display during playback with adjustable timeout durations. Direct USB and Favorites browsing on the touchscreen without needing your phone.

Next-Generation Room Correction

BassFit integration automatically aligns time and level between your main speakers and subwoofer for seamless low-end coherence. SurroundFit calibration provides precise automated alignment of front, surround, and subwoofer channels for immersive experiences. RoomFit+ evolution delivers tighter bass response and improved transient handling. CenterFit phantom center creates adjustable vocal enhancement for improved dialogue clarity. Context-aware bass management assigns independent crossover and gain settings per source. Discrete dual subwoofer control enables independent calibration to smooth out room modes.

Smarter Audio Processing

Scenario-based presets for Night, Dialog, and Sports modes powered by our 10-band PEQ engine. Adaptive dynamic loudness using Fletcher-Munson curves to preserve bass and treble at low volumes. Pro-grade filter import from REW or AutoEQ. Advanced profile management for transferring correction data across devices with Expert Mode for weighted measurements.



Connectivity & Ecosystem

Adaptive source profiles let you customize EQ curves, volume, display layouts, and grouping logic per input that automatically engage when you switch sources. Universal hi-res multi-room with expanded support across Roon Ready and Google Cast endpoints. NAS Mode (SMB Write) transforms the devices into network music servers, managing and transferring files to your USB drive wirelessly. Native Plex integration with Plex control. Complete overhaul of the internet radio engine for faster buffering and higher bitrate streams. Expanded wireless subwoofer protocol to Roon and Google Cast. Support for USB libraries up to 200,000 tracks.

Smart Home Integration

Deeper Home Assistant integration with support for presets and alarms. Native Apple HomeKit and Shortcuts support. Smart input switching that preserves playback context and volume states.

Future Concepts Under Consideration

Specialized streaming integrations for Idagio (Classical), Nugs.net (Live Events), and SiriusXM. Personal cloud locker support for Dropbox, OneDrive, and iCloud, allowing you to stream your collection directly without a physical NAS or USB drive.

What We've Already Delivered​

Visual personalization with new VU meter styles, dynamic music spectrums, and expanded clock faces. Native WiiM Home App on Apple TV, Google TV, and FireTV. On-glass navigation for local radio and recently played tracks. Home screen widgets for iOS and Android. Precision volume with customizable remote steps. Multi-point room calibration. Per-output EQ. Advanced DAC filter settings with user-selectable interpolation filters (Amp Ultra).

Flexible wireless home theater supporting scalable 4.0, 4.1, and 5.1 channel configurations. Smart presets that trigger complex routines—setting input, volume, EQ, and grouping simultaneously. Persistent grouping for fixed speaker zones. Native YouTube Music support. Completely rewritten USB media engine.

Your Suggestions!​

These roadmaps are a starting point. We're watching your responses, reading the threads, and paying attention to what resonates. If there's a feature you're interested in, say so. If something doesn't make sense for your use case, let us know, but be respectful. Not every feature is going to hit for every person, a feature you’ll never use might be exactly what someone else needs.

We're building this with you, not for you. The difference matters.

Yessss!

 

[Fletcher Munson]

I miss traditional bass and treble controls; the pre-programmed presets don't quite work for me, and setting them up sensibly isn't easy either; the more sliders, the more difficult. The built-in graphic equalizer always reminds me of cheap amplifiers and boomboxes; better amps have bass and treble controls, or none at all. There's also a parametric equalizer, but to use it properly, you probably need a degree in that field.

PEQ is the best, well worth spending some time with imo

 

[Fletcher Munson]

No, that's certainly not a valid way to judge an amplifier's quality.

The most useful tone control I ever found in any sort of audio gear to this day is Quad's tilt and bass lift. I'm happy to still own my Quads, but don't currently use them. If I had to choose between an amp having either only this ingenious tone control or only RoomFit and a 10 band PEQ, personally I'd always go with the latter.

I use old quads with the tilt controls, i like it but prefer the PEQ as well.
My NAD pre-amp though has excellent semi parametric eq:

 

[Matias]

WiiM Ultra definitely needs a balanced version, even if using TRS connectors as Topping does to save space.

And amps having both RCA and TRS accordingly.

 

[RyanWithWiiM]

A lot of the items on the roadmap sound very interesting - I'm looking forward to see how this develops!

@RyanWithWiiM @WiiM Team Do you mind if I ask a few questions on some of them?


Is this an evolution of the current automatic subwoofer and loudspeaker sync function; and if so, will it now use the phone built-in mic / external mic (i.e. like RoomFit), instead of the WiiM device built-in mic?


Is this just alignment (i.e. relative channel delay adjustment) or will it also include frequency response correction filters (i.e. like RoomFit, but for 5.1 layout)?
At the moment EQ and RoomFit don't seem to work when Dolby 5.1 content is played - which is IMO very unfortunate.


Does this mean you are considering adding phase response correction to RoomFit (e.g. like in Dirac Live or Audiolense, which can e.g. remove crossover phase wraps)?
Will this be optional and configurable?


Does this mean stereo bass (where one subwoofer plays left channel bass and the second one plays the right channel bass), or that we will be able to use both subwoofers in mono (L+R) configuration to optimize bass response over several seats (like you can do with Multi-Sub Optimizer or with Dirac Live Bass Control module)?
Will this only be possible with 2x WiiM Sub Pro, or will other solutions be possible as well?

E.g. a very interesting option would be to be able to use a dedicated WiiM Mini driving just one (or both) non-WiiM wired subs with content below the crossover, and paired with a master WiiM device which is driving the main loudspeakers with content above the crossover.
That would open a lot of possible configurations and flexibility.


Note that the Fletcher-Munson curves are a very old variant of equal-loudness contours. The most recent version is defined in ISO 226:2023, so I'd recommend to use those as a baseline for the dynamic loudness feature.

If we normalize ISO 226:2023 curves (e.g. to the 80 phon curve, as that is close to a standard monitoring level used for audio production), we can see that there's not much change to treble level between individual curves (and what there is happens mainly at very high frequencies and at very low levels), but that there's significant difference in bass level between them:
View attachment 31869
(Source: ISO 226 curves were traced from this article with WebPlotDigitizer, and normalized in REW to the 80 phon curve)

Given all this, it is my opinion that a dynamic loudness feature should mainly adjust bass amount, and that treble adjustment should be minimal (though I personally believe treble adjustment is not really needed at all).

Lastly, this kind of feature needs to have a calibration function, so that the user can adjust the reference point to match their own listening distance, preamp/amplifier gain and loudspeaker sensitivity.
Unfortunately, no generic reference setting will match every environment.


This sounds very interesting, but I have no idea what it might mean. Could you give us some hints?

Thanks for all the great work so far!

I'll flag your questions with the team, but at this stage of development, any answers they have may change.

I like Matias' idea for balanced outputs on an enhanced WiiM Ultra. I'd lean toward creating a new, sonically-enhanced Ultra product as another offering in the Ultra flagship series for those seeking the pinnacle of WiiM sonic performance (e.g., Audiophiles, nerds, WiiM-ophiles...) coupled with the best UI out there (WiiM). Here's a short list of ideas for the enhanced WiiM Ultra that I hope you smart folk will add to:

Balanced outputs (go big with nice XLRs);
High-quality, outboard power supply;
Dual ESS chips;
Analog, resistor-ladder volume control, so we don't lose bit depth at lower volumes;
Decoding for Ultra-hi res formats - DSD512, PCM 768kHz, and MQA(?);
Retain Phono in;
Connector for external Wi-Fi antenna;
Larger screen;
...

And how about that catchy name (Ultra++, Ultra Sonic Supremo, Ultra Pinnacle, Ultra Apex, or Ultra Ultima...)? Sonics first but help me out with a fun name here.
I love all the ideas in the roadmap even though I may not use some. Choice! Sincere thanks to the WiiM team for their dedication, kindness, responsiveness, and patience!!!

 

[KolegaPaweł]

I beg you make better custom presets. I would love to set in preset flat/bk/harman curve from room fit + dac filter+ sub on/off+ crossover. All options from all app in preset.

Why so many people want a bigger screen? To make anything visible, the screen display would have to be significantly bigger - then it doesn't fit anymore size standards Wiim follows for years.

If you want to see more, connect Wiim device to your TV or PC. You can do it.

Keeping the device low-profile is more important than having an enlarged screen

 

[Burnside]

All I can say is that the team has it on their list as something they want to do. Right now, I'd personally put it low on the list as something likely to happen based on what I know, but it'll be a huge win if they can pull it off. I imagine it'll take a lot of work with partners to make happen. But for now, it's on the roadmap.

To answer my own question and that of @M1ke2345 , Google suggests:

“Apple HomeKit/Shortcuts: These use the HomeKit Accessory Protocol (HAP), which operates over Wi-Fi, Ethernet, or Bluetooth Low Energy (BLE) [1]. AirPlay is a separate Apple protocol used specifically for streaming audio, video, and screen mirroring, not for general device control or automation [1]. Devices with native HomeKit support communicate directly with your Home Hub (like an Apple TV or HomePod) using HAP.”

So maybe AirPlay etc is unrelated and not required.

However, googling also suggests:

“If you intend to develop, manufacture, or distribute a HomeKit-enabled accessory for sale, your company must enroll in the Apple MFi Program. MFi licensees gain access to:

• The commercial version of the HAP specification and HomeKit Accessory Development Kit (ADK).
• Certification tools and testing processes.
• The "Works with Apple HomeKit" logo and identity guidelines.
• Access to secure authentication components (either software-based or hardware chips). “

…which probably takes us back to square one

NAS Mode (SMB Write) transforms the devices into network music servers, managing and transferring files to your USB drive wirelessly......... Support for USB libraries up to 200,000 tracks.

This interests me. But only because I'd like my wiims to not be dependant on my smartphone. So if they made a half decent stab at a music server, that I can navigate with a remote, then I'd plug a usb drive in and off I go.

I can't see it though.

For now Emby have an LG TV app that works perfectly with my remote. I resist it because it resamples everything before it gets to my ultra but no more. It still sounds great and if I didn't read all this mcguffins on the internet about high Res, room fitting, eq, snr, dac chip blah blah blah I'm sure I wouldn't know the difference.

I'm very happy with my wiims overall and consider them money well spent.

 

[HoosierHiFi]

Like I said, I'll start looking elsewhere.
Let the children play with what they want to.

So far my WiiMs are running trouble-free. But as soon as any of those Gizmos start to interfere, be on the app side or the machines themselves, that'll be it for me.

Bye, Felicia!

Perhaps it would have been better to ask for an appropriately larger screen, sized in proportion to what might be a slightly taller enhanced Ultra, to fit the enhanced hardware list. I'd like to see album art from 3 meters away. Phone, TV, or PC distract from serious listening.

I’m sorry, but how does a display on the amp differ from these? Especially one that you either have to struggle to see, or would otherwise have to be ridiculously large to see from three meters away? I find streaming from my phone to be the most convenient of all my options, particularly if I want to view album art or anything else related to what I’m listening to.

And you still need your phone for music selection anyway

You are correct that the display is not the distraction, 'tis only I, the user, choosing to be interrupted by texts, emails, and critical cat videos. Still, my Bluesound Icon is more readable from across the room. Overall just wanting WiiM to expand the Ultra series with an upgraded hardware version, the Ultra Sonic Supremo. Any thoughts beyond the size of your screen for hardware enhancements?

Hello,

RyanWithWiiM​

I love my WiiM Amp Ultra but I wish You add small track progress bar on the bottom in Minimalizm Playback Screen.

Something like this:



It would be very helpful

Best regards

Nothing wrong with mini XLRs for balanced applications:

Eight, lovely streaming presets allow me to ditch the phone for much of my listening! What a gift! I think I read another suggestion to make it 12 presets with triple-clicks. Back to the hardware enhancements, any ideas?

Nice, I like the form factor. Who uses it besides Topping for hi-fi, and where can you get good cables to mate with conventionally used XLRs on high-end gear?

 

[EddNog]

Topping doesn’t use miniXLR; they use 1/4” TRS balanced.

Hart Audio uses miniXLR for their modular headphone cable adapters. It’s also possible there are some headphone brands using miniXLR for cable connections to their cans. Not sure where else miniXLR is used.
