Soldered a new jack onto a cable and it now sounds darker than before. Why? in Repairs and Technical Posted 5 hours ago Sorry to be sensible, but when you say "darker", do you mean fatter, with more lows? If so, it could be that you have improved the lead, which you say was a cheapie, by making a decent contact between it and the new plug (which, being a Neutrik, probably makes a better connection than the old one). The highs could be the same as they were, but you perceive it as darker/fuller because you are now hearing the low end properly as well.
