Vintage preamp/amp power cords

Let me just say I don’t want to start a discussion if power cords make or don’t make a difference. I’m just curious to know if folks with older gear with captive power cords mostly considered a replacement with IEC type plug. The power cord on my McIntosh MC2200 is literally a little better than a high quality modern lamp cord, But it’s been there for almost 30 years. The main objective of the replacement would be safety as well as Sonics, if any.
