I don't know sleepwalker65 if you're one who has yet to realize the value of a good power cord, or you can't see the forest for the trees. Either way, check it out: The improvement going from old oxidized lamp cord to a new high end power cord is many orders of magnitude greater than any possible losses from adding another connection. Heck you could twist the wires by hand and still be better off with a good power cord. You could for that matter throw ANY aftermarket power cord on there and be a whole lot better than the old lamp cord that's on there now.
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.
