Just like many components in a hifi system, there is a addiction for the holy grail. After a point it's a case of diminishing returns. Factors like your age ( related to frequency) , the quality of your set up, your room, cables/ connectors etc all play a role in your listening experience. Many snakeoil solutions are out on the market. It's a never-ending debate. If you have researched and are convinced that a switch will make a difference in your setup , go for it. It just might be psychological. If you can borrow and audition a audiophile switch ( SOTM etc) it would be an ideal scenario. All the best
