WiiM Amp discussion

It shouldn't be an issue here when so many other products manage this fine with per input volume control even at lower price points (eg Arylic B50) and higher prices points (NAD D 3045). I could understand it for a dumb DAC, but not a smart, connected streaming device in 2023 with multiple inputs.

Having been into hi-fi since the mid-80s, I don't think I ever turn anything on without checking the volume, so I suppose it's a problem which is alien to me, though I appreciate it may well be different for others. It's just what you're used to, I suppose.

The device is marketed towards consumers. It does not include separated dac, Amp, whatever. If step 2-3 of the volume scale is able to kill your speakers, it’s an issue. They will fix it. Pretty sure its not a big deal. However, I dont like that they didnt test this beforehand.

I think part of the challenge here is that this type of device encourages you to change your source input frequently eg Chromecast wifi streaming session back to TV HDMI ARC for some YouTube videos, etc. Integrating the TV HDMI ARC support makes it more of a constant use item vs setting aside an hour in the evening to spin a record on a home HiFi setup, so the usability should be more accommodating. In any case, it should be a relatively simple feature improvement so hopefully WiiM can resolve it in a future firmware update.

I wasn’t aware it was that extreme. So that’s step 2-3 out of what? 10?
 
Sometimes i wonder if people still have a self functioning brain. It takes a lot to kill your speakers. Why would you ever put volume to 100%, if that kills your speakers?

Different source volume problem aside (which can be fixed) some of you guys really make a problem out of nothing.
It's not a matter of intentionally setting your speaker to dangerous listening levels. With a fully integrated device with digital control, you will often need to set higher volumes to compensate for sources being lower output. For example, HDMI ARC is inherently lower volume than WiFi streaming. Certain video sources (like a bad remux) can result in you having to crank the volume even higher. You could end up needing to get to something like 80% volume on HDMI to achieve normal listening volume with certain media. On the WiiM amp, when you then switch back to WiFi streaming from HDMI ARC, if you don't first lower the volume before switching or immediately press pause after switching and then adjust volume, you will then absolutely blast your speakers because where 80% on HDMI ARC with your video was normal listening volume now on WiFi streaming it's nearly overdriving your speaker. I stumbled into this first hand yesterday, because I expected the WiiM Amp to function like the majority of other integrated amps or streamers currently on the market (eg NAD D 3045, Arylic B50 and others) and manage volume independently for each source. I agree it's not a showstopper issue, but I don't think we should apologize for WiiM missing such an obvious safety and usability feature.

very loud doesnt kill your speakers. E.g my DBR62 can take 120W which the amp cant provide. I understand the problem of the different source volumes, but you make it sound worse than it is. Also this was always a problem before digital volume existed too.

I'm glad that it's not an issue with your particular speakers! Enjoy manually adjusting the input volume every time you change source.

Jesus christ. Not everybody is living in his little HiFi cabin in the woods. I have neighbors and a life - no time to worry about manually checking if switching back from a movie night to spotify will actually wake up everybody in the street.

My understanding is that even if your speakers are rated for 120w if they are fed by a 80w amp that is clipping into distortion territory and overdriven then that signal could easily damage your speakers.

The solution would be simple, the question is why doesn’t WiiM offer for its streamers (w/ DAC) and amp the ability to adjust the gain or attenuation per source in the app.

The old Yamaha RN602 had this fantastic function. My wife feels we’ve downgraded, not upgraded.

I’ve raised a ticket.

@WiiM Team fyi, hope you’re reading.

The WiiM team don’t often frequent forums, so as you’ve done and as per the large drum people will know I often beat, the best way of attracting their attention is to submit a ticket thru the feedback section in the app. You may not always get a direct response, but at least the request will be logged in their system and hence have better visibility. And the more who do so, the better the chance they’ll do something about it :)

Hi, in the interim using bespoke Alexa routines might help either requesting them from an echo or the WiiM voice remote as per this link

Heya, I just had my Wiim amp delivered today, and thought you guys may appreciate a couple of internal pictures, not great quality pictures as I didn't want to unplug the daughter boards, and glue. I also want to give Linkplay props for not glueing the case shut, it's the 4 rubber feet which pop off with no glue and 4 screws under them, and the bottom cover pops off with a wireless antenna attached. The mainboard with the gigantic heatsink attached needs prying out, and you have access to everything.

The heatsink is much larger than expected it's a nice touch that the aluminium case is used as a heatsink for the power MOSFETs and the SOC for the A98 module is cooled by it's own heatsink which is attached to the case.

Can you power up the amp with the cover off?

I'm sure many of us would love to know which coil is the "whiner". Shouldn't be too hard to distinguish by listening close to one coil while blocking others w/ foam or whatever.

If its the one in the top left of your photo, no amount of additional "hot snot" is going to quiet it down!

I think you could, I didn't as there is minimal human protection against mains voltage, but you don't need to disconnect anything so you could have full functionality without the case. although they have used a lot of silastic which alone is more than you'd expect at this price.

Also mine as zero coil whine, or if it does it's drowned out by my GPU.
 
New firmware (5.0.540148) changed the power consumption in stand-by mode, it's now about 3.8W, device is no longer warm in this mode. Unfortunately, buzzing noise is still there.
From talking to customer support, buzzing will require a hardware replacement.

Please check the pcb version. Its engraved in one of the corners
