Ok, so what I've gathered here is that the better a component is, the less it needs a tweak yet the more it is affected (not necessarily improved) by one.
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?
