Something like the Roksan Attessa might be worth a shout. It uses BluOS (so not shit) and it is a solid amp. Put it with something like Q Acoustics Concept 30 and it’ll sound pretty good and it’ll just work. At no stage will you be called out because it has stopped working.
A leftfield option is a defunct premium surround receiver and a streamer like e.g. Bluesound Node.
Just picked up a Harman Kardon AVR 8500 for EUR 150, which was MSRP 3k.
( -Edit: usually around EUR 350, still a bargain.- )
Node N100 is used around EUR 100 or Node 2 for around EUR 200.
Leftfield speakers: Arcam Muso, picked up for EUR 100, including stands. (most offers are however without stands.) Incredible sound, you look for a subwoofer that isn’t there .
A receiver is more versatile too, as you can hook up your telly and bluray on it. No need for HDMI, just use Toslink.
And it leaves you sufficient budget for turntable, phono pre-amp if desired, or vinyl.
Yes - it’s very good. Takes about half an hour of microphone faff to get the first reading but once you’ve done that you can take the default curve or set up several of your own, which can be switched on or off via the app. Lots of videos about how to set up and you can download presets too.
