Sonos is actually the way I go with my tv. I have one of those bases under the tele and a couple of 1s as the surrounds. It’s expensive for what it is but it is just so easy for the odd film and the sports I watch in surround. My tele has 5.1 pass through on the optical and I control the volume on it with the usual remote for the tele. It can be cheaper than what I paid too as the smaller beam and the IKEA sonos lamps which can be used as surrounds have come out in the meantime.
As a streamer for the stereo they’re a lot more expensive than what they should be but the app is very user friendly and if you’re a Spotify streamer the lack of proper hi res support isn’t going to be an issue so much for you either.
I’ll be really interested to see what you make of that Black Ice amp, they’ve been getting really press and they do sound like a really interesting prospect.
