I'm buying caps for a preamp upgrade (Sol Sammet is doing the mods) and scrolled through Percy Audio's last couple of pages where he sells the tweaky stuff. One of the tweaks is Bybee filters. They were a big craze a couple of years ago and they pop up from time to time. Are these still used on speakers? Do you put one on the positive lead only? Or, do you put them on the crossover in the signal path for each driver... The latter seems to be the way I remember it being done in the past.. .but I can't remember.
Anyone using them today? Are they worth $92/ea?
