Okay I use a Signal Cable "Magic" Power cord with my Manley Labs Chinook and it makes a big difference. What I found was a much tighter overall sound if that makes sense, everything improved. Also, putting some brass weights or something to dampen the metal screen casing from vibrating that is a key tweak, imo. Keep in mind that the Chinook is not a heavy piece of gear and the Signal Cable IS, the connection and cable are massive be ready to support it in someway also order 2 feet more than you need this stuff dosent bend easily!
