The time coherence stuff is super interesting to think about too. Not sure how it would affect some recordings more than others, though. Any ideas about that?It has been a few years since I performed a lot of comparisons in my system between having my DEQX HDP-5’s function which improves a speaker’s time coherence turned on vs. turned off. (My speakers are Daedalus Ulysses, btw). But as far as I can recall mediocre recordings of complex material, such as the example I cited earlier of orchestral recordings having overly bright massed string sound, particularly tended to benefit.
The degree of improvement provided by that function was less predictable with other types of material, and I wasn’t able to identify any particular type of recording (e.g., poorly recorded/well recorded; simply mic’d/heavily multi-mic’d; classical chamber music/pop/rock/jazz; vocal/instrumental; etc.) which was especially likely or unlikely to benefit.
In any event, though, it was rare for a recording to sound worse with that function engaged than with it disengaged. And most recordings sounded noticeably better with it than without it.
