The 1’s and 0’s don’t pass through the power cord. An upgraded power cord will only have a noticeable effect over an inadequate power cord that does not deliver adequate power to a power hungry component like an amplifier. Streamers are not power hungry components. A power cord can not magically convert bad power from the wall outlet to good power to the component. If you have bad power you most likely need another power cleaning component to do that. Your likely better off spending your money on connections that actually do transport the 1’s and 0’s.
