The operational and service manuals have lots of information, including a caricature description of the filters. However, I located Sony's white paper on the SCD-1 which has more detail including frequency responses of the 5 filters. However, I want to look at how the reconstructions affect the time domain. I'm developing a mental framework, but that task would be more effective and productive with more information.
Do you know where that filter discussion / information might be found?
