TWL - I believe that the reason that you like the Bybee filters is because they eliminate some of the sibilants caused by wire in your IC's and speaker cables that has jumbled crystal lattice. If you replaced this with wire that has organized crystal structure, you could probably eliminate the filters.
This is the reason why so many folks believe that stranded wire is worse than solid wire. It's because cold-working the wire to braid or twist it into stranded bundles damages the crystal structure and sibilants are the result.
This is also why direct-immersion cryo damages the sound of the wire - the crystal structure is then helter-skelter, not well-organized. This causes reflections and current-bunching in the conductor.
