I'd rather stick with a well known brand with a good reputation, like Onkyo.
The way I read it. It has a built in Alexa compatible functionality, a bit like say a smart plug. The dot is to actually give you Alexa to use with it. So doesn’t need plugged in but does give you voice control.
Sorry i meant that rhe receiver has alexa built in i believe. I assume You need the dot to male alexa work???
Amazon is probably sponsoring it as a freebie. Gives the retailer the ability to say it supports streaming while amazon try’s to get a new subscriber.
Don't see the point of the dot
