I recall a Rolling Stone Magazine interview with Donald Fagan a few months ago to where he was talking about the pitfalls of recording software. How these progerams are used to make something sound too big and perfect.
The openess, tonalitiy, and all the intracasies in a recording are not there.
There is somewhat of a colder sound then on vinyl or cassette.
An acoustic in the old analog recordings does'nt ring out as much. On cd it sounds more clangy and cold.

I recall record company people in their business suits going to used stores and to record collectors because they lost the master recordings to a lot of those old acts.
Some things are just going to be gone with the sound from the original.
And once it is gone, it is gone forever.
