Wow. This opened a can of worms. What I have to say is that “generally speaking”, the better quality the system, the greater its ability to demonstrate the sonic improvements in tweaks ( ie better power cables and interconnects, footers, power supplies, etc). Think of your system this way, it is a system of parts and components that all work together. From the breaker box, the wire up to your listening room, the wall outlets, power cables, power regeneration or conditioning, to the components, interconnects, speaker and subwoofer cables to the speakers and subs, it’s a system and every part matters. It may even be along the lines of the sayings regarding the “weakest link”. Well if all your links are lousy, replacing one of the lousy ones with a great one may not make a lot of difference. But if your links are generally really good and you replace one with an exceptional link, now you may hear that difference since the rest of your chain or system has been well optimized. So I say the better the system , the more likely there will be sonic benefits from tweaks.
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?
