Yes, I was running the audio sync feature. My Wiim was set to fixed 100% volume as I was controlling through my Denon. The tones to sync audio with the TV were full volume. I thought my speakers were ruined as they were only rated for 145W (Dynaudio Emit 20). Thankfully no discernable damage to the speaker. My ear drum is a different story. I posted on the Wiim Forum and it looks like it got escalated to the devs.

easily mitigated by using passive attenuators on the input of the amp, so that full output from the DAC is at (or a little above) your highest listening volume.

Wiim too?It seems that the paranoid me will never get better.
I wonder and really-really expect to see the new advertised Eversolo safeguards against it (on top of the analog VC)
My MiniDSP Flex has never screwed up in this way.
Not that it would be a problem if it did - it's normally set at about -3dB

Truth is I never heard horror story for Flex.
For 2x4 on the other hand... Child diseases I guess.
I have two preamps: a ProPassion (passive) and a Bryston BP25.
Both gather dust because all the DACs I've had (Yulong, Mytek, SMSL...) I've always connected them directly to the monitors and I've never had any problems or risked causing damage.

The new Schiit Saga 2 is a pretty nice preamp. 4 inputs, three gain levels, both RCA and XLR out to amp, remote control. Alas, does not have phono preamp or tone controls, but I guess you can't have it all. I am enjoying mine, plan to pair it with a Schiit speaker amp eventually.
As much as I like it, as I have written elsewhere, it has made me appreciate all of the functionality packed into my older NAD 1020 and Nikko Beta 20 preamps. I like both of these preamps, apart from the weird horizontal jack panel on the NAD.

I appreciate you sharing this experience. I'm using my Wiim Ultra as a preamp sending signal directly to my Yamaha M-70 power amp. I will be turning down the attenuators on the Yamaha as soon as I get home to avoid this potential catastrophe.
That is a nice amp.
Sure, I'm interested. Shall I PM you for details?

Definitely NOT the Topping Pre90 - having done a tear down on one I was very disappointed to find that its key components were only OPA1612's opamps and a 20 year old Texas Instruments headphone amplifier chip (tpa6120a2) costing $3 and $2 respectively.
Hardly state-of-the-art tech as was claimed at the time I bought it.
There is also another chip footprint under the OPA1612's once they are removed - which would indicate they made another version of it - possibly a "White Glove" version?

If you think your personal Pre90 is bad, prove it.
Measure it.
Otherwise, please stop.

Agreed @ZestClub I refer you to the discussion that led to this https://www.audiosciencereview.com/...-pre90-review-preamplifier.18283/post-2152070

not so much a passive preamp, as a simple volume pot in a box.
You can dispense with it and use the digital volume of the Pro+, there will be no audible deficit by doing so. You could also if you wish use the pot to limit the maximum volume from the amp when the Pro+ is at maximum, and then use the digital volume control down from there.

Thanks! I tried the WiiM’s digital volume control for a while and prefer the passive preamplifier. The wiim’s other features are fantastic.

since the subject's kinda, sorta come up -- and since I am never rarely ashamed to display my digital ignorance 
-- if someone is so disposed, please help me to understand digital volume control. I certainly don't understand how it works, but I have an impression from something I read, heard, or was told long ago that resolution (i.e., in the amplitude dimension, not the time dimension) is lost when a signal is attenuated in the digital domain(?).

To me a preamp (an amplifying stage before another amplifier) implies an active amplifying device. A volume pot in a box with the requisite audio jacks does not have that, so it's merely an attenuator. That can be a completely serviceable replacement for a preamp in some settings, though. Just don't call it what it's not.

Well, whatever it’s called, that step attenuator built into an enclosure with bits of wire, jacks and a knob and placed previous to the amplifier has become indispensable to the enjoyment my hifi experience!
They can work quite well if you have adequate gain in your system and don't need additional amplification. A fringe benefit is that the attenuator adds no distortion to the signal, too.
