Digital sound is not a richer sound spectrum. The lack of frequencies below 200 Hz makes music sound like its played through an old time telephone line or a ventilation duct.
Digital sound is more dangerous to your ears than analog!
I am quite sure that 90% of all speakers sold today can't replay the E(the lowest tuned) string on a bass properly.
This is the reason many music lovers starts to buy Vinyl Records again and play them through analog amplfiers and real speakers with a frequency range from 20 to 20 000 HZ.
