I know for a fact that for every $1000 you spend over what you previously spent on a particular component, the sound quality increases 10K based on the unquantifiable fact that your system must assuredly sound better if you keep spending more and more money on it. In fact, I change out my cables every six months as once the newness factor wears out on the cables, the "clarity and accuracy" isn’t there anymore. I am 1000% convinced of this because otherwise, I would have to admit I’m wasting money.
As for my DAC and Streamer, I update those once a year because I can’t trust the hardware to accurately reproduce the song that is being sent over 1000s of miles via various hardware and network switches. Plus, Quboz, Tidal, and Spotify wouldn’t tell us something different than what they can actually deliver.

Joking aside...
I have a Cambridge Audio CXN V2 and streaming Radio Paradise, local radio stations, and use the onboard DAC when playing CDs, I find the quality is better (cleaner and a tad brighter) than what I get through my Marantz stereo receiver which has a decent DAC for the $. But the cost difference between the two is not 1000s of dollars. And yet...Spotify sounds better through the Marantz than the CA...go figure.
My local stations SQ varies depending on the music being played. Rare vinyl cuts of cajun swamp pop will sound very different than the Classical station using DDD CD sources. No streamer can fix the source.
