What i have found is the best audio components respond and show more about what the better tweaks and cables and conditioners do in a system so my answer is tweak away to get the best sound for any level of component.
True or False?
Many high-end manufactures deny the benefits of tweaking their components with upgraded power cables, fuses, etc. We all can agree that even the best speakers respond to room placement but is it true or not true in (your experiences) that the better your audio components are, the less they respond to various tweaks?
