Why a Purité Audio forum?

hi keith just seen this hope it gets a bit busier soon

I would like to replace my Pass Labs crossover and reduce the number of boxes in my system. I have three way and considering adding a sub , would the Illusonic be the solution ?

'Grounding' boxes, a relatively new phenomenen , boxes often sealed to deter prying eyes filled with what looks like clay, cat litter and bent coat hangers. There is no electrical connection just plugged in to an unused preamp input, the only difference measurements show is a slightly increased noise level caused by the connecting cable acting as an aerial.
