@ditusa Thanks for that link. Doug Blackburn and I both wrote for Soundstage at the same time, and I always admired his depth of knowledge. There were some really interesting discussions behind the scenes at Soundstage between the two Dougs at Soundstage (Blackburn and founder Schneider) about the virtues of time/phase coherence that was a most interesting read. They completely disagreed with each other and both made very valid and interesting arguments, but it was always respectful and I learned a lot from that discourse. Anyway, thanks again for that dated yet still very useful link — I bookmarked it for future reference.
