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.
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.
Can you power up the amp with the cover off?
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.
From talking to customer support, buzzing will require a hardware replacement.
yellow transformers. I posted pictures of it
Please check the pcb version. Its engraved in one of the corners
