Hi experts. Im new in this mastering realm. Should replicated CDs sound different than the DDP master? and if so, how different? What do you answer to a client that was happy with the final master but unhappy with the replicated CDs? The replication house say they did quality checks and everything was performed "as always". How do I know if I did something wrong? How do I prove the replication house did? Whats the procedure to null test the DDP against the replicated CD? I´ve read some confusing stuff on other forums, so I want to get more info on this topic.
