Yes it was that I wanted to buy a better quality box than the firestick but it seems the Firestick is better than all the expensive ones anyway with my system as it's the only one without lip sync issues 

Many different Firesticks and picking a good one matters. We have 4K Max ones in our primary TV sets. Resolution is important if you have a 4K set but the 4K works fine on our old HD Sony too. CPU and memory matter, even if you don't do anything fancy, the faster response to commands is worth the few dollars more. Not saying the others are bad, we have a couple so old they have been discontinued still working in other rooms.

I've seen articles about newer devices, sound interesting. Not getting the "horrors" over sideloading being gone on newer models. We haven't done since we got started many years ago so it isn't an issue here.

On the new versions, we will wait for user reports, not so much professional reviewers, and may upgrade if there are significant upgrades available. Like with our Sonos the replaced units will move to other locations displacing the oldest ones.

There is a lot more to the Vega story than stopping sideloading. Worth reading about if you are concerned.

And I see the reason some folks are unhappy.

Hence why I wanted to move away from Amazon
