LOL I drank the snake oil too!

In reality if you want better sound, buy better headphones and speakers.

Great drivers + good amps > good drivers + great amps

Honestly, it’s not that big of a difference. Like yeah, in a critical listening session I can tell but these days I just want to enjoy my music. After listening to a few songs I forget what hardware I’m plugged into anyway.

Tubes are cool for the novelty factor, but these days my headphones stay plugged into my solid state 99% of the time, mainly for the heat and power. You can also add the harmonics in software to simulate the warmth of tube amps, so there’s that.
