Could someone enlighten me of the difference in the audio formats. I'm aware of Dvd-Audio and SACD, but I have read they are analog and not digital like CD. I would have thought DVD-Audio was just a DVD without pictures (taking it to the basics). Do you recommend DVD-Audio (I don't have anything that plays SACD. If this is the wrong place to post this, I'll take it elsewhere, but I would appreciate suggested listening on alternative formats (oh, I don't do vinyl). I'm into classic rock, alt. rock, post-rock...thanks. NeilGabriel<--says it all!
