Wireless multi room speakers

[ChrisTheMusicLover]

Has anyone come across a way to have 5 small (less than 6inches in any dimension) speakers in a house that's on 2 levels, connected wirelessly to the sound source. Each can be set independently for the volume and a alarm? Not completely sure on the sound source, I do have the paid TuneIn and also Alexa on an Echo. Looking for really good quality sound, but with an eye on the cost being as low as possible, within that.

Thanks all, I will look into those ideas. If there's any more, please post them.

Also, I do have TuneIn (which is very irregular in it's reliability), but if you wanted to play any radio station and any podcast in the world, plus any track from 12,000 tracks on a hard drive, what would you choose for the source please?

Thank you both for your input. I will look into this some more, although the price is a little steep for my wallet at the moment.
