WiiM News This Month​

WiiM Amp Ultra and Ultra Awarded SoundStage! Network Product of the Year​

Both the WiiM Amp Ultra and the WiiM Ultra were recognized for Exceptional Value in their categories, streaming integrated amplifiers and streaming preamplifiers.

It’s a simple label, but it carries weight. “Exceptional value” only lands if the fundamentals are right. Sound quality, usability, and features that actually matter. And the price has to stay grounded too. That balance is what we were aiming for and we're happy it hit just right.

What's New This Month​

WiiM Home App v3.5.2 dropped on March 13 with a couple of genuinely exciting beta features and some solid under-the-hood improvements:

• Simultaneous Output (Beta) – You can now run Optical/Coaxial and Line Out at the same time. Perfect if you're feeding a DAC and a powered sub from the same device. Enable it in Audio Output settings. (Currently requires the Ultra beta firmware.)
• Simplified Stereo Pair Setup (Beta) – The pairing flow just got a lot less fiddly.
• Per-Input Screen Control – Turn the display on or off depending on the active source.
• Delay Firmware Updates – You can now hold off on auto-updates if timing matters to you.
• NAS browsing cache improvements and better handling of Custom Radio file names on iOS round out the release.

Community Buzz ​

If you haven't checked the forums or r/wiim lately, here are a few conversations worth catching up on:

Home Theater with WiiM (No AVR Required) Users are building clean 4.1-style setups with Amp Ultra, wireless surrounds, and subs. Lots of good discussion around HDMI ARC, phantom center channels, and getting great movie sound without a traditional AVR. Join the conversation:

Vinyl Meets Multi-Room Real-world setups running turntables through WiiM devices and distributing audio across zones. Great discussion around external phono stages and getting the best from line-in. Join the conversation.

Custom RoomFit Target Curves Power users sharing their approaches to dialing in sound beyond the defaults — an ongoing thread since September that keeps getting better. Join the conversation.

Quick Wins: Everyday Feature Ideas Simple ideas like one-tap "All WiiMs" group buttons are gaining traction here. Good place to drop ideas and see what resonates with others. Join the conversation.

What firmware will include the option to delay automatic firmware updates? I don't see that mentioned in the most recent ultra firmware announcement and don't see it in my app.

It's still coming, the document team was a bit ahead of development for that feature.

RoomFit™ Settings Deep Dive – Now with Flat, B&K, and Harman curve explanations + graphs

@RyanWithWiiM May I suggest to update the description of at least the "Flat" target curve to be more factual?

The current description:

Characteristics & Typical Users

• No bass boost and no treble reduction
• Technically neutral and analytical
• Often sounds accurate but slightly thin or bright in normal rooms
• Commonly used by studio engineers and for audio measurement or speaker testing

The above seems like the 'flat' in-room response target may be confused with a 'flat' on-axis direct sound response target - which are two very different things. As such, it may also mislead readers.

Basically, a neutral loudspeaker which measures 'flat' on-axis in an anechoic chamber *WILL NOT* measure 'flat' in a room; there it will have some downward slope (how steep depends on loudspeaker directivity characteristic, listening distance, and how reflective the room is).

This means that a flat target is only really 'neutral' under very specific circumstances - e.g. in anechoic rooms or free-field conditions (i.e. where there are no reflections at all, only direct sound), or potentially with ultra-nearfield / desktop listening (where direct sound is heavily dominant).

But if we EQ a neutral ('flat' on-axis) loudspeaker in a typical living room to a 'flat' target with RoomFit, we will effectively make the originally neutral-tuned loudspeaker sound bright (i.e. its on-axis direct sound response will now slope upwards).

So if we consider loudspeaker directivity (which increases with frequency with most loudspeakers on the market) and room reflections, it becomes clear that in practice RoomFit target curves correspond to the following tunings:

• B&K target: neutral tuning, preserves loudspeaker's flat on-axis response
• Harman target: warm tuning, adds some bass boost to an otherwise flat on-axis response
• Flat target: bright tuning, results in an upward slope to the loudspeaker's on-axis response

So ideally all target curve descriptions would be updated accordingly, but IMHO the description for the 'flat' target is the most in need of correction.

On an unrelated note, may I suggest to also update the "Smoothing" section with the 3 new options which were recently introduced?

And lastly (a bit off-topic, sorry), I'd advise to consider updating default RoomFit settings to a configuration that is more likely to work well across diverse environments (or at least less likely to degrade sound quality). My proposal would be to use the following as defaults: B&K target, frequency range 20-300Hz, variable smoothing, Non-Boost Mode enabled.
