Apologies, but here's more procrastination incoming. Possibly more suited to the Streaming sub-forum, but the overarching question remains and I don't want to clutter the place up with another thread.
Q: What are we actually paying for?
I'm guilty here of reading specifications and butchering technical understanding rather than listening to music, so this will be full of holes but bear with me.
My understanding is that Tidal (and others) offers (up to) the highest quality streamed music to consumers. I believe that if my home network is fully operational (it's FTTP and seems very robust), then my WiiM Mini has the chops to handle the Max quality Tidal source, and that the DAC in my amplifier can decode the entirety of that signal, which it receives through an optical connection from the WiiM.
So all things being equal, purely on a technical level, my system to that point is retaining all the detail that it can from the source?
Therefore, what are the tangible benefits of me replacing anything in the setup? I'll need analogies here but if we look just from a streaming perspective, why would I spend multiples of what I have spent, to "upgrade" anything - the streamer, the amp or the speakers?
I'd love to dive headlong into Hi-Fi but on my simple (and no doubt naive and incorrect) technical level, I struggle to appreciate the actual benefits. Does expensive kit "just" lend a particular sound to what is otherwise the same source?
I just can't see what I'd gain at all from changing the WiiM but do concede that there are likely some benefits to upgrading the amp and speakers, but whilst I'm just thinking in textbook rather than listening chair terms, it's hard to wrap my head round.
