There are actually 2 seperate hobbies here.

The thrill of conquest when searching for the next great thing is what I enjoy. It could be finding that rare or special / sentimental record, or tracking down a highly sought after perfect piece to the equipment puzzle. Sometimes it’s just figuring out what the next pursuit will be. It’s all a great big, exhilarating adventure that never has to end and will always have surprises waiting to be found. 

I agree with the OP that there are two hobbies here.  I would say that 80% of my time/ effort is spent on music.  I've been branching out lately finding "new to me" artists and genres that I've overlooked in the past.  

Of course, most music people are always looking for the great recordings.  You know you're in that club when you have multiple recordings of the same piece of music.  

Occasionally, I make a hardware upgrade.  

i'd like to say i'm 95% music, but that would be delusional--in fact i vaccilate between 50%-80% music, since i'm always at least thinking about the gear
