Jack Bybee and I had a long conversation about this. I have found that Bybees are filters and after I mod a component, I remove most of the filtering, except for that which is necessary for the DAC chip. I often find other modders putting Bybee filters inline with the digital signal. This is not a good idea in general, so I remove them. Jack evidently has some new silver Bybee filters that operate at much higher frequencies and have higher Q. These may be interesting for digital.
Bybees for power delivery may make sense, but they are very expensive IMO. I am working on several battery-powered projects, which I believe is a better solution. The battery supply for my Off-Ramp is not too far off.
