Curious, if I'm using my Audiolab 9000A dac, will this Plus version offer any benefit?

Yes, well. @Kachda any source?
Well, it's no longer a rumor...

"In regards to the Parametric Equalizer (PEQ), we are currently supporting four bands. However, we understand that our users may have diverse needs and preferences. Therefore, we are committed to continuously improving this feature based on the valuable feedback we receive from users like you. If there is a demand for more bands, we are fully prepared to incorporate this into future firmware updates."

Thank you for another comprehensive review, (and to @onlyoneme over on the WiiM site too).

That's a tremendous value streamer/ DAC with perfectly adequate ADC (and room for improvement).
Basic PEQ coming... It's a great starter package and WiiM mini's allow cheap multi-room.

Only potential concern is plugging this (Pro+) straight into powered speakers with no safety on the volume control. Is there anything in the design to help with this?

Nice kit, nice review:)

in general these are solutions on balanced inputs .. so in any case preferable to integrate a suitable preamp stage..

(besides any idea of the output impedance of the pro "plus" ?)

There are also RCA inline attenuators, worth consideration.
Pro Plus impedance is lower than Pro's for sure as I've seen that during my measurements.

Despite the DAC section, is there any difference with the WIIM PRO?

Thanks for the early review @VintageFlanker

As I understand it, there is no change performance gain (over the Pro) if I use an outboard DAC. Correct?

I use a Pro to a D90SE

Thank you for the measurements, @VintageFlanker!

A small suggestion: Don't format text to be black or gray. It'll be essentially unreadable for people using ASR's "XF2 Default Dark" theme:

Thanks for the review! I would rather have seen a better ADC, and have the WiiM Mini have an improved DAC instead, with the way I'm using/trying to use WiiM multi-room. The release of this unit doesn't look like it really changes much, if anything, for me.

Now I'm confused if the official name is Pro Plus or Pro+. My box is labeled with Pro+. On amazon the device is called Pro Plus.

With a decent EQ, it would be a great replacement for my Preamp/DAC/WiiM Pro, I would try and set the gain on my amps to limit output a little to keep things from blowing up, then again an affordable Pre-amp with trigger on/off would work too.

So is the internal DAC a good replacement for the SMSL SU1 DAC? Looks like the SMSL is a little better, but only 5db better SINAD?

If you'd like to slim down your setup, the Pro Plus's internal DAC would be a good replacement for your SU-1.
