AAC 256 should be at least on par with MP3 320 CBR, might also be on par with ogg vorbis at the same bitrate

YouTube Music Premium offers AAC 256kbps as the highest quality.

Opus 128 is only for the audio of YouTube videos. Not YouTube Music.

Not everyone can discern the difference between a 96KHz FLAC and 256kbps AAC. I can’t. But I still can (barely) tell the difference between 256kbps AAC, and 96kbps AAC.

But I can tell if a song was well-engineered or a mess.

I believe those who can’t discern the difference between bitrates (especially on high bitrates), but have the appreciation for good music, good mixing, and good mastering, can still be considered audiophile.

In Indonesia, the tap water is not drinkable. Some gets their water from a nation-owned Drinking Water Company (PAM; Perusahaan Air Minum).

The situation is similar, they contain plenty of Chlorine to prevent bacteria from growing. But the distribution system might not be the cleanest. So usually people buy gallons of mineral water and put them into a dispenser.

Some others, takes their tap water from groundwater, pump it into a water tank, and use them. It is not drinkable either.

At home I use Reverse Osmosis dispenser from the groundwater, and it goes through a reminalisation process after the filtration process. I’ve been drinking with this setup for over 15 years now.
