First let me say that I am technically very adept, having been a DJ and software engineer. I have installed or upgraded many wired (and more than a few wireless) sound systems.
In November replaced my old Definitive wireless system with 3 100’s (2 of which are a speaker pair.) Also purchased the Pro-Ject-1 turntable.
Wow, what crap this is. Oh yeah sounds great when they work. BUT...speakers drop off, or the sound goes out, OVER AND OVER. There is NO interference, the speakers are all close or even in the same room as the router.
Last night we had a party, and just as people were arriving, BOOM, the Sonos app/Spotify once again could find no products. After unplugging everything (including the router) and firing them all up again, it sort of worked, but the speaker pair was gone and I had to set that up again.
Anyone without the technical proficiency of myself would have been at their wits end. I got it work (again, this happens just about every other day) but I was so angry that my party was no fun at all.
