That certainly seems to be the consensus. Some of the (obviously more encouraging) topologies I've tried sound almost acceptable just on the first "mash the number pad" test. It seems related to the total delay time in the loop(s), ignoring the APFs, which I guess isn't surprising. I saw your posts with Keith Barr on the Spin Semiconductor forum, and I think his "one big loop" topology really has a lot of advantages that way. When I built it I didn't have any context and didn't expect much (it's a tutorial, after all), but it was immediately surprising. Multiple parallel loops seem to "fight against each other" a lot more. Tuning a single loop algorithm feels more like "enhancing and improving" rather than "making it less obviously bad".
I wonder if the constant density parallel comb filter case can be improved by using fewer combs and adding more output taps per delay... I suspect it's really only trading one problem for another...
