My Acoustics professor in college was fond of saying; “Aperture is aperture,” meaning that the quality of audio is directly tied to the size of the reproducer. While it’s possible to fake higher quality audio by adding reverb or fiddling with equalizers, now 60 years later it’s still true that for best audio quality you need physically large speakers. The speakers in any notebook computer or smartphone don’t qualify. So, while lossless audio can play through a computer speaker, the result will not be lossless due to limitations of the physical size of the speaker.
The problem is that large speakers take up a lot of space (doh), so few people have them anymore, and most people under 50 have never heard superb quality reproduction audio that compares to live performances.
