You don't have to use that high values in BOSOZ. In some cases 2uF is enough and 10uF is plenty. Sometimes bypassing larger caps with small ones makes improvement, sometimes makes it worse. It all depends on type of a cap you use. I made experiments with 0.1uF bypass in crossovers and in some places MIT RTX sounded better, in other places Hovland musicaps. Hovland to my ears seem to increase the feeling of air and space, RTX sound very sterile and Jensen polystyrene I tried were very mellow and dry. On the other hand in my DAC MIT RTX sounded the best as the input coupling caps. Some people say that it's better to avoid capacitors at all, but after all those ties I might suspect that sometimes they can improve the tonal balance of a system.
