Not surprising about the MP3 pre-echo. I remember reading a comment while back, I think it was in Reddit. Someone posted a comment about how they bought a CD that have 50s/60s music for their grandparent and gave it them as Christmas gift. Their grandparent are graceful about the gift but they didn't use it very often. They inquired about why they are using the vinyl over a crystal clear CD. The grandparents said they loves the hissing and other sounds that are prevalent on the vinyl. They said it made it part of the music and they have strong memory of it during their era. The CD completely removed those sounds and felt it is unnatural sounds they are not used to. They felt it is too clean.

People have strong relations with their musics that they are used to while growing up. Nostalgia are powerful memories and they don't want their music unsullied from something that they grew up with.
