For example:
- if the cables result in significantly more bass you may need to adjust the toe-in or the distance between your speakers in order to achieve the most natural sounding bass.
- if the new cables result in more clarity, again, repositioning the speakers may result in significantly better imaging.
Also, an example of the effect of changes in acoustics (unrelated to any system changes) - I’ve just finished applying acoustic treatments to my room and I ended up changing speaker position after applying each treatment in order to achieve the optimum image and bass performance.
Of course - it can also be dependent on the acoustics of the room - my room is only 15 x 12 x 8(high), which comes with it’s own set of challenges in the form of standing waves and reflections.
I have no experience with larger rooms, but I believe they all have their own unique challenges as we implement different cables and components.
But I do agree with Schubert - allow the cables to settle/burn in before making any changes
Good Luck
