The headphone recommendation is really great for 2 reasons.
1) no room reflection. What you hear is just music.
2) very easy to get 100+ db. Some really good headphones like the Meze Empyrean, maintains full composure regardless of volume.
The "audiophile gear" I REALLY need is a damn house.
I'm here in my apartment trying to enjoy the Coachella streams and feeling self-conscious about 30 measly watts because my always-quiet neighbors have their front door open trying to enjoy a beautiful spring day. I need a house out in the middle of nowhere so I can actually turn up without bothering people.
