I swear my system is playing 3D chess now with this new power cord!! Seriously, though, actually, it’s kind of lame to have a run-of-the-mill power cord on an expensive audio component. In isolation, perhaps it is adding to overall fidelity. Perhaps… only an A-B test could bear that out. But forgoing this AudioQuest Y3 for the lesser chord… would that improve things? I doubt it. So I’m quite happy I have invested the money to gain whatever edge a higher quality power cord may offer. Does my vehicle run better on premium fuel? Undoubtedly. I’m assuming the same principle applies here in audioland.
