Indeed, if it sounds better to you, go for it. Just keep in mind it’s all placebo.
However, I can say with most certainty that the sound coming from your speakers is 100% identical
It’s not placebo though. I have found the differences in sound between a $2 factory-supplied cord and a well-built high-end cable to be drastic, and repeatably so. I’m sure there are instances where cables don’t make a big difference, but so far I’ve found upgraded cables to help with each piece of equipment I’ve tried one on: amps, DACs, preamps, etc. The funny thing about it is that I didn’t want cables to make a difference - I didn’t want to spend money on them. Then I heard the differences clear as day and came to understand that cables are components that you cannot overlook if you want a truly high-end system. Mzkmxcv, do you have a revealing system? Why not just try a 30-day money back guarantee power cable in your system and see if you can hear it?
