Hi-fi components

I would like to set up a listening corner in my office. I already have the speakers (Teufel Ultima 40) sitting around, now I need the driver. Use case and requirements: I mostly listen via streaming (YouTube Music, occasionally Tidal HiFi, via Chromecast Audio via Toslink). If Google (Chrome) Cast is missing from the driver, I definitely need a Toslink connection for the existing Chromecast Audio, preferably two, to be on the safe side. Phono would also be good for vinyl later. Bluetooth (with a higher-quality codec, e.g. AptX [HD] or LDAC) and AirPlay 2 round off the whole thing. Usable/operable internet and DAB+ radio reception would be the icing on the cake! I don't see Google, Siri and Alexa Assistants at the moment. But if it's supported, why not? Proprietary (Multiroom) solutions in addition to Google Cast/AirPlay 2, such as Denon's HEOS, Yamaha MusicCast, Sonos, I'm not a fan of... But I can read up on it. Budget: Rather entry-level for 500.-. But if the component is worth it, e.g. in terms of future-proofing, or range of functions, or sound quality, it can go up to 1000. I've seen it: I like the Yamaha R-N303D for 400.-, it is often praised, P/L is great. I don't know what the difference is to the older 402, which costs about the same. You could also split the receiver into network player and integrated amplifier. I like a Denon DNP-800NE over the PMA-800NE (unfortunately not available at digitec). The combination is available from competitors for 1000. With the vinyl on top, it looks really classic (I don't need CD/DVD). I see the 2-piece combo as nicer to separate, upgradeable (at least the DNP on top regarding media formats; amplifiers certainly last forever). But I'm not really sure about the advantages. Just discovered: Cambridge Audio, e.g. the CXN V2 in combination with the CXA 81. What devices! But yes, we would be talking about over 2000. It is noticeable that more money is often paid for stereo alone than for AV. Audiophiles seem to be ripped off again... Personally, I prefer dedicated stereo with excellent operability via the display on the device, IR remote control and additional Assistant/App for convenience. Current situation: I have had the Denon AVR-X3500H in my living room for 2 years, in a 5.1 setup (2 Atmos speakers are still missing due to a lack of players). An 82" LED is still used for the picture, but the 77" OLEDs are now becoming more affordable... There's music playing all the time. But I like the setup quite a lot. What I miss is an operation (at least On/Off) via App. Or even via Smart Home. The Yamaha seems to be able to do this. With the Denon, HDMI CEC simplifies a lot, but of course none of this works for the Chromecast Audio via Toslink. I would be happy to hear your opinions, experiences and tips!
