Speed is probably more a function of clarity on the leading edges of sounds (or said another way higher bandwidth)
Hence adding a superior power cord that renders the leading edges of percussion for example will manifest as improved timing. That’s certainly been my experience and the current range of AudioQuest power cords are exemplary in this regard
