There are some interesting things here.
1. Define ’hobby’. If you’re not making money at listening, isn’t every interest that isn’t a profession a hobby?
2. Yeah, the original conjecture is the ’Missing the forest for the trees’ argument. It basically sums up what we think of as obsession. Obsessive behavior is a high attention to detail coupled with a diminished ability to decide what is truly important to focus on. Don’t mistake obsession for passion. The operative distinction is that an obsessive listener becomes fixated on something on the way to their ultimate goal to the point where they lose their focus on the goal itself.
3. A truly exceptional sound system is beguiling. Many recordings simply sound great even to the point where a mediocre or tangentially interesting piece of music can just blow you away simply on the merits of its qualities, like tonality or texture. But the overall piece itself is perhaps just decent and not earth shattering. I’ve listened to many things where I thought, this production is amazing. This has no right to sound as good as it does. That’s totally a thing.
4. Part of the journey of the audiophile is, in finally reaching a point where the system is objectively ’very, very good’, we have to pause and take stock. Why did we set off on this quest for great sound in the first place? Now that the system isn’t an impediment, what should I listen to next? The problem is, the (audio) world is now my oyster and what do I do with all this amazing possibility. Many listeners just crater when confronted by the vast array of choices. They were so busy learning how to listen that they weren’t actively thinking deeply about what to listen to.
For me, the point of listening has always come from and returned to a place of joy. Whatever I am listening to, it is going to be the result of a conscious, mindful decision. I never feel guilty about what’s spinning or streaming and I never tolerate any material that I don’t find fulfilling or satisfying to whatever I’m feeling passionate about at the moment.
For me, the 13th Century poet Rumi sums it up perfectly:
"The quieter you become, the more you can hear."
On the surface this can be read as referring to physical stillness, but there’s a lot to unpack about us, our striving, and about letting go of that and just returning to listening from a place of joy.
You have to go through years, decades!, of trials of learning to truly hear, learning about all the ways that audio can sound bad, and how to avoid those, before you arrive at a place where none of that is a barrier to what you originally wanted. Once you arrive at that destination, and this can be done! you have to be able to put all that baggage down and get back to what originally set you on this path in the first place.
You’ll have experienced a lot of music and learned a lot along the way. The person you are will inevitably be changed by your experiences on the journey, and so, a conscious effort is required to discover who you are as a listener today. That is a challenge we should embrace and not shrink away from. That's when the fun really starts! Some people sadly do get fixated on the journey and never arrive at its end. That's sad, but that's the nature of people. It's certainly not all audiophiles by any stretch.
