When you change cables or even tighten them you are possably affecting the sound. If you intend to change things try cleaning the ends and connectors then restoring them AS IS. Now listen to them again BEFORE reversing or changing them to see that the real effect of your experiment is not just a better clean connection.
Rogue Audio Cronus .... reverse polarity ?
Just for fun, I reversed the + and - cables on the speaker end of both speakers, and the music seems to sound a lot better. Is it possible that the amp's polarity is reversed at the speaker connectors, so that the amp sounds better with the speaker end of the cables also reversed ? or is it just my imagination? Have any other Cronus owners tried this with noticeable results ?
