When I look vintage amps, preamps etc. they almost always have non detachable cable which only has two wires. No ground. And they have RCA inputs and outputs.
And there weren't many cases of ground loops back then, right? Things were simpler up until the nineties, i think.
Is it the introduction of the PC to audio chain with their switching PS that made a mess and introduced various ground loop issues?
Since my system is very susceptible to ground loops, I am slowly replacing everything that has RCA with XLR components (whether they are differential topology or just cmmr transformer based).
But I might go the other way, I am thinking.... Finding components that are single ended, but are without mains ground. I know it is not safe to just lift the ground when there is no double insulation sign.
Is it so hard to engineer an amp or preamp or whatnot with double insulation symbol and without the need to ground it? Are there any advantages of components that need to be grounded?
Sorry if i made some mistakes with terminology. Hope you get my point.
Thanks
