Vibelink small pop sound when it goes into standby

[anonyless]

just got the Vibelink, it is excellent. but I can't figure out the small pop I get (sound come from the speakers) every time it goes into standby ONLY -
i have it connected to the Ultra with RCA and toslink inputs , same thing happens no matter on which input it's set to.
tried turning its volume all the way down - same.

right now it's connected to the Ultra with RCAs, Toslink, short (stereo) trigger cable. tried disconnecting the trigger cable to see if it makes any difference, but it doesn't.
also I should mention, it doesn't matter how it goes intro standby (button, app, Ultra triiger) - I always get the low pop sound.

it's not a big deal, but was wondering if anyone else experienced this issue

Mine popped when I turned it off via the app.
Not uncommon on amplifiers.

Hi Mr Ee, Team

Please update the Vibelink firmware using the WiiM Home App. Simply move your mobile phone close to the Vibelink Amp, and the app will automatically detect the device and begin the update process.
Give it a try, and let us know if everything works smoothly!

Done that, update applied. I'll see how it behaves over the next couple of days.
Took me a moment to remember I had to enable bluetooth for this to work!

However, when I use the 'power' button for the vibelink within the Devices screen to turn the amp 'off' I get a pop through the speakers.
Same...

Yes, it is normal. No problem.

I think it's a bug - a really small one, but still

I don't think so. As @Mr Ee said, it is common in amplifiers.

As far as I know, most D-class amps with TPA325X and PFFB have pop noise at power on/off.

The WiiM amp has no pop noise, but the WiiM amp pro and amp Ultra have the same pop noise.

Other,
Topping PA5
Fosi Audio V3
TP RA3
etc. are also similar.

so we'll to agree on disagreeing
the Vibelink replaced 3e audio A5 for me, which doesn't have any pop when turned off/on

ASR measurements have shown that pop noise is generated when the 3e audio A5 is switched on and off.

3e Audio A5 Stereo Amplifier Review

This is a review and detailed measurements of the 3e Audio A5 Stereo class D amplifier. It was sent to me by the company and costs US $229.99. Despite its simplicity, the A5 has very well thought out features. Clipping indicators are provided for each channel. And selection of inputs is made...

couldn't hear any pop from the speakers when the A5 went into standby - only its relay clicking sound from within the amp.
I'm not trying to make a big deal out of it, just wanted to make sure this is a known issue /bug / "thing" and that the amp I bought is 100% fine

You can submit a request ticket via the feedback section of the WiiM app.

Honestly I was concerned about this pop noise when the WiiM amp pro was released and asked if it could be improved by submitting a ticket. The team is aware of it, but it probably won't be easy to remedy.

Again, I don't consider this a bug.
