An interesting discussion. Not one I feel will be resolved any time soon, but interesting.
Qobuz user here. Also, owner of a myriad of media as well (hi-res downloads, CD, SACD, and vinyl). For me, the beauty of Qobuz is the instant access to a vast array of music that either a) I discovered via Qobuz or b) I discovered somewhere else and looked up on Qobuz. I realize the version on Qobuz may or may not be the "best" version and often times, if I find a better version, I'll listen to that one instead (including purchasing it). But just having access to that online library for finding new artists and recordings has been awesome. Sometimes the same album on Qobuz is offered as a CD quality and a hi-res quality and I will listen to both. Most times the hi-res quality sounds better, but not always. Same thing goes for Qobuz vs. vinyl. Or Qobuz vs. SACD/CD.
For me, being an audiophile is about recognizing and striving to get better sound within your budget, whether it be through playback equipment or source material.
I started out in high school with a Kenwood receiver, Radio Shack speakers, and a Sony CD player (I added a Fisher tape deck later on). I was all about the WATTS. How loudly could it play? I would not have considered myself an audiophile at the time. I think this is where most people who aren't audiophiles stop.
At some point between my senior year of high school and my freshman year of college, I discovered that not all watts are the same and that equipment matters. However, it took me another 5-10 years to understand that the source material matters just as much as the gear you play it back on. Looking back, I would look at my college years as "collecting" music. Now, I try and "curate" it instead.
