Charles1dad, well in retrospect and not having removed all prior HFC stuff perhaps a better way to say this is that it gave the biggest jump. When Rick was here, we put it between the wall and his Waveguide power center and after it settled in and we listened, I just looked at him in disbelief.
But I would certainly try a HFC pc first if you can try pcs then ics and speaker wire, etc.
