I'm not a computer expert at all and I wonder why just a few bands, comparable to the current ones, haven't just been added since September for pro and pro plus... ??
any ideas from programming specialists???
Your observation -- going to 6 or 7 bands is "easier" than going to 8 or 10 bands, so therefore could have been accomplished sooner -- is largely correct from a simplistic perspective. But from a practical, total efficiency-of-workplan perspective it could be considered a resource-consuming intermediate objective. I would expect Wiim tries to minimize perturbations to the realtime data pipeline, since its mission critical. Substantial testing and verification would take place before rolling out any changes in that area. Doing that on an interim 6 band release would arguably further delay the 8 or 10 band scenario.

The original rollout of the current 4 band PEQ probably didn't push the envelope on system CPU/memory resources; I'd guess they were more focused on stability, fidelity, few/no bugs, etc, so the implementation may have been more brute-force than highly optimized. Now they are working on performance optimization, which is non-trivial work on an ARM SoC running DSP-ish instruction set extensions, HW accelerations, etc.

I can't fault Wiim for narrowing this to a one-and-done effort to get the most PEQ their HW resources can possibly support. I can, however, fault them for grossly misjudging the timeline to achieve the objective. Things are one year or more delayed from the original "announcement" of improved PEQ. Not a good look. But hey, all of use will gladly take a 2 year late 10 band PEQ over no expansion of PEQ at all. So we wait, some more patiently than others.

I agree on the whole, but it hasn't been over a year since the 4 band PEQ was introduced, has it?

Pretty much every sub allows polarity inversion, anyway, so having it in the app is more of a convenience feature.
Example: if you are 90deg out of phase at the acoustic crossover point, inverting phase will make no difference (now you are -90).

Delay and phase are both crucial to proper sub integration. I use both often. SMAART doesn’t lie.

Thanks for the example. Nobody said otherwise, I hope.

Still, every sub has a polarity switch, so what is really needed in the app is a delay setting.

Singed up and asked for main speaker delay in comments. :)

Just purchased the Wiim Amp. Sub out and bass management was the main selling point. Mains delay is only thing missing for me.

Just a question to you pros. I am a proud owner of the WiiM amp and I actually like the usability. HDMI ARC runs flawless with my Samsung TV, which most other Amps/Streamers/even AVR are struggeling with. The amp itself, however, is not really powerful enough to drive my speakers. Before I was using a purifi amp and a RME ADI-2 FS (via optical) and the holographic soundstage was stunning. Now my question:

Is there any chance to solder etc. a pre-out port to be able to connect an external amp such as the purifi? (Only for the smart ones: The WiiM Pro Plus has pre-out but no HDMI support)

You might wish to hang on for the Wiim Ultra due in a few months time which will have all the functionality of the amp HDMI ARC etc and with line out .

Are you really sure that the WiiM Amp isn't powerful enough for your speakers (what speakers?) or could it be it's just not as loud as you want it to be? Some people - not you - can hear congested sound when they just see the volume control above 50%. ;)

Generally, there's no problem with setting the volume as high as needed, unless 100% is still not loud enough. Obviously, quite some users are suffering from rather low output levels (which have nothing to do with insufficient power) depending on the source. And by source I mean the actual source, not the source setting on the Amp. WiiM seemingly have been very careful, probably too careful, to not ever overdrive the inputs, even with the highest level sources. I wish they would allow some per-input digital gain, even if it reduces SINAD. Maybe they will at some point in time with an upcoming firmware.

Nevertheless, if you cannot live with the status quo or if your speakers really are too power hungry (I don't know), you should stick with what @Petevid recommended. The Amp is so tightly packed, I doubt anybody could add a pre-out in his home lab.

What about a speaker-level to line-level output converter? https://www.crutchfield.com/S-qBuvi...-1-2-Speaker-level-to-Line-level-Adapter.html, for example. If you’re handy with a soldering iron, it’s easy to make one yourself using a few resistors and doesn’t require modding your Wiim Amp.

Thank you for your answers. Well, it is not about the level of volume which is more than ok, it is all about control and sound quality, in respect of bass control and mid high detail. It was a significant donwgrade to what I had previously connected to the same speakers. Don't get me wrong, it is a decent device, especially for the budget, but far away from what I am used to. I was hoping with a preout the situation improves. Again, the stability and usability is awesome and I don't want to miss it. I think Petevid is right, I just have to wait for the WiiM Ultra...

I had the same experience. People told me I was wrong. Pretty big jump in cost but I went with a nad. Hdmi arc was important to me along with size. I will be willing to check out the next wiim with preouts.

I purchased the Wiim a few weeks ago, because of the all-in-one solution it is, and so far, it has been absolutely terrific for me and I plan on buying a second one to put in my wife's office.

With regards to the issues other people have noted about the lack of power, I am in a fairly small room, about 9 feet from my speakers with a wall behind me, and the Wiim has more than enough output for my Revel M106s. It really is an awesome little box.

One of the best features about the WIIM products (like Sonos) is the ability to link them together to make multiroom music systems. I have purchased the WiiM amp to stream music in our workout room and stream bluetooth music and instruction from our Peloton products to decent speakers. But I also have 3 WIIM pro plus models to play music to out ourdoor area, bedroom and family room. By linking them all I can stream the same or different music to each room with control over each room individually or all together. I still have my listening room with a hifi system but with the WIIM setup, even the spouse and kids can stream music throughout the house without asking which remote to use or how to turn on the system, it just works.

@amirm Thanks for your test and reviews!
I have a WIIM Amp for one small room and Topping PA3s + WIIM Pro for a second larger room. Reading your reviews, I thought about an upgrade for a large room.
There I got big 3 band speakers. What do you say about the connection Topping PA5 II plus + WIIM Pro plus? Will such a set be noticeably better than WIIM Amp?
Also, I think such a set will be in reserve for the case when I manage to purchase higher quality floor acoustics.
