This is a most excellent place for technology news and articles.
It's a great service. I found several of his expertly-created 78 tunes on there that I hadn't heard in decades. (Some scarce stuff is almost never NOT available on 33 or 45rpm)
Another reason: Some people get deeper into multiple pieces of music because they like to compare performances of them. Fidelity doesn't matter a whole lot. You want to compare how some bands or singers performed a (non-hit) song recorded in the 1930s or 1950s. You listen around the fidelity. People in the 1950s made million-selling hits everyone heard on AM radio or 45s. Fidelity is over-rated.
