> How can audiophiles continue to exist with knowledge being so easily available? And how can someone be clever enough to be a software engineer and not clever enough to figure out crystals in bags taped to cables do not affect music quality.

I consider myself an audiophile because I hear a difference between no amp+dac sennheiser hd650 vs with amp+dac. so when you ask "How can audiophile continue to exist" ? thats a bit of a dumb take aint it?
