WiiM Mini Streamer

I see. Did you consider the cheap generic DACs? Most of them have decent sound quality for what you are trying to do and won’t have hum. Here’s a $12 one

I didn’t, but it would have been a good idea.

I have the Mini and I am happy with it. Looking at ASR's list of streamers and it seems to place a head or equal to the Bluesound. Its' performance is bested by the Pi based solutions (DACs are better) and ranks 3rd in SINAD. Once connected to an external DAC (Soncoz LXD1) how could I complain? When using Alexa and the Mini as an Alexa slave, do we know the optical output in Bitdepth and rate using Amason HD Music files for the Mini?
Any insight would be appreciated. Multi-room is a wonderful world and so easy now.

Got one , to replace a chromecast audio and it sounds great
Running it in 24 bit 192 KHZ, through optical, using Topping Dx7 Pro DAC
 
OK, enough dinking around with code. Here's the "final" script, driving a crappy little 3.5" screen similar to this one, with a Pi 3A+ that I happened to have in a drawer (good luck finding any Pi right now). A Topping Topper for the Wiim Mini.

I really don't like grabbing and unlocking my phone to see what's playing while listening to a radio stream or playlist. This little display will always show what's playing. When done streaming, it shows the date/time.

The new wiim apps update suppose to have bit depth and sampling rate on UI but I’m not seeing it.

I reset the wiim and it check the update but did not find any. Today's date is about to be over.
 
@WiiM Support

On behalfe of many Wiim users around the world, please make this few things:

1. When using fixed volume we want to use +/- buttons on wiim to next song/previous song. Please! Its super easy to make i think

2. When wiim goes to sleep/standby can light can goes off too? Thats the way we can see when wiim is in standby.

3. Can wiim app can show bitdepth/sample rate of current stream/song? Last update note that, but when using Spotify Connect there is no info about that on now play screen.

Re 3, please see the response above
 
see (and it may be related to the meaning of this site), if their engineers can study the subject of the jitter which seems quite high on the toslink output (more than the small chromecast despite its age!)...
if just hardware, or can be care to bring to the firmware?
;-)

Hi,

I bought a WiiM Mini Streamer for 99EUR.
Connected by optical TOSLINK to an optical splitter. One output of the splitter goes into a Topping E30 DAC and then to a headphone amp. The other output of the splitter goes into an optical input of my AV receiver.

There has been a firmware update a few days ago with the new features:
- bitperfect TOSLINK output. So the sampling rate/depth is identical to the source. Up to 192kHz 24Bit
- switch for fixed volume, so no influence from the streamer (no DSP processing etc)

I am using it with Amazon Music and Spotify.
From my understanding the optical out should now send the original music signal to the DAC without having any influence on the music quality.

Is there any chance that a (very much) more expensive streamer can have any advantage in audio quality? Or only snakeoil?
Just speaking about digital out, not the DAC inside the streamer.

Cheers
Mario

Hey Mario, just saw this. I'm running the same Wiim Mini with a Topping E30. Quite a combo for not a lot of money. Very good stuff.
 
New firmware being rolled out in batches over the next few days - response for WiiM just received:

”The firmware( 4.6.415059) update that support display bit depth and sample rate is performed in batch such that the devices are taking turns to get update. All the devices will be updated during the next few days
  1. New Feature - Display sample rate and bit depth on the WiiM Home app
  2. Fixed - Random playback stuttering (from 44.1k/16 up to 192k/24) not due to network bandwidth
  3. Fixed - M4A decoding compatibility bug for TIDAL Connect
  4. Fixed – Incorrect red color LED even the network is connected
  5. Fixed - Random no sound issue for AirPlay 2 during multiroom playback
  6. Fixed - No sound issue when switching to ‘work with Alexa’ mode on certain use cases
  7. Fixed – The connection loss of TIDAL Connect after playlist is complete (need one extra device selection) “

You should create a separate thread with steps on how to do this. I have a pi and would need screen and step by spte instructions for the software
 
Sorry if this is a silly question, but how do you change WiiM’s WiFi hotspot? Can’t seem to find a way to do it in the WiiM app

Can’t see it either - I guess you may need to reset the device and set it up again which does seem like a sledgehammer to crack a nut…
