Stanmore III

I have the same issue with the Marshall Stanmore Wifi speaker. Connected a mixer panel with some microphones to it to do karaoke, but it's impossible due to the large delay of the speaker.

I have a Marshall Stanmore III connected to the WiiM Mini through Line-in and the sound is crazy.

Interesting. I am playing guitar using RCA from a Boss Waza TAE core into my Marshall Stanmore iii and I have no noticeable latency whatsoever. I do have some small amount buzz tho.

If you’d like a single Marshall speaker, look at getting a Marshall Stanmore III, or even an Acton III if you want something cheaper. You can hardwire the turntable to either of those models, and even the Acton III has great sound.
