I'm a 56-year-old who built tube amplifiers and did Ham radio as a kid (WB2BIU), but who is a boob regarding computer and digital audio (I quit in disgust when the transistor became the rage 40 years ago - the first KLH transistor power amp was three angry cats in a small box, horrible when transitioning from KLH 9 electrostatics driven by early Futterman). Can anyone point me to some Web sites that have an overall description of the issues regarding using a computer for music playback (no interest in recording, though would like to copy my analog and redbook DC collection). I got EMU 0404 last week and instantly noted improvement over soundblaster, especially running into Gilmore Lite, but 0404 has controls and switches (and names for things) that overwhelm my little point-to-point wired mind. Am good with computers and software, so don't need handholding in that area as well - just have anolog brain wanting to understand (and at least try) digital audio world. Thanks for any help.
