A family member is an audio engineer (now also a producer) who owns a good recording studio, and we’ve A/B tested lossy vs lossless on good equipment. He hears things that I don’t, my ear is somewhat untrained. But at mp3 bitrates below 320, I can hear compression artifacts, especially in percussion instruments and acoustic guitar. But if you’re listening in your car or while wearing Bluetooth earbuds while you’re out walking, you probably won’t notice unless the mp3 bitrate is really dismal.
That sounds like conclusive proof that sound quality is determined by the shittiest component in the signal chain.
