Yeah too much choice. For example this is stereo, but do you have any plans to go home cinema? If so you'd need a integrated amp with HT bypass. Or you could get a AVR and that'll function as a stereo amp and have useful things like room correction, bass management, auto setup, HDMI, down mixing, also audio streaming and bluetooth.
And for speakers you have different styling, sound presentation, bookshelf, standmount, tower and big towers.
Different streamers, do you want one music streamer, or plan to have multi room? Do you want a single eco system that can be controlled via a single app?
A all in one may work, and you like some parts of it, but may find the streaming not the best.
If you just get a good stereo integrated amp that allows you to have choice in steamer, whether that's Sonos, Squeezebox, a generic Android kodi box, Bluesound, Google boxes etc.
Also the amp may or may not match well with the speakers or your personal preference.
Best to go to a shop, look at stereo/amp combos first, put your attention to that, then look at CD/Bluetooth/Streaming functionality.
