The Redbook CD has been around for over 30 years.
The sound quality of CD's has "improved" through the advances of digital processing in most newer CD players or DACs.
I started my CD collection in the mid 80's, there were some CD's that I had thrashed, but others that I have kept and is still playable.
I am now listening to the Japanese pressing of Billy Joel Greatest Hits Vol I and II, print 1986
Also in my collection is the MFSL Japanese pressing of Alan Parsons I-Robot. I think this was first printed in 1984?
Even the jewel box has the words "Patent Pending" and "8" embossed on the back bottom right corner...
My current system does a wonderful job extracting the bits from these discs, but I'm pretty sure the remasters of the albums would be a huge improvement.
What is the oldest redbook CD (playable) in your collection?
