The digital recording and mastering technology has improved to a much higher level since you were buying CDs (especially Redbook). However, there have been many negatives along the way; have you heard of the "Loudness Wars?" This came about due to all the kids using ipods and wearing earbuds; the record labels decided to compress the music so it could all be heard loudly thru ipods.
So, after 2000 we have superior digital technology, but most CDs are mastered with high compression resulting in poor dynamic range. Classical and Jazz are the exception and can compete in SQ with high-end vinyl. In recent years, many artist have grown tired of having their albums ruined by the label and the engineers, so they are now remastering their work. Some of it is quite good.
As far as SACD, there are limited recordings compared to Redbook, but a few record labels are committed to the format. But to get the most out of these formats, good hardware is essential.
