Everything and Nothing / Re: Early Japan CD pressings vs. everything else including recent remasters« on: December 09, 2015, 06:03:22 PM »
Hard to know if you are imagining it or not. Early CDs that were reissues of old classic albums sounded different from region to region mostly because of the master tape used at the time. What would happen is a master recording is made at the studio (I am talking analog tape here). After that the master tape was then copied several time. Due to the nature of analog tape if you make a copy of a copy the quality of the sound goes down. Some times several generation of copies were made which where then sent to different parts of the world where they would then make vinyl masters from those copies. When CDs first hit the market in the 1980s, they would take those same tapes and would use them to make the CDs. So, depending upon where the original master was kept, one version of the CD would sound better then the rest. As an example The Who's album Who's Next the US version was considered the best sounding CD at the time because the original master was used instead of a copy of it. On the opposite end Jethro Tull's album Aqualung, the original US version was considered one of the worst sound CDs issued because they used a copy of the master that was several generations below the original.
