PS Audio PWD MKII HiFi Tuning fuse direction

The fuse sits in the AC circuit .... I go along with the alleged efficacy of a lot of hard to rationalize tweaks, if someone says they hear a difference. But directionality of a fuse in an AC circuit goes too far even for me.

Well now, I suggest you try it both ways and get back to us.

Well, I can't say which way is correct on the PS Audio, but it's worth getting the direction correct. I heard a pretty clear improvement with HiFi Tuning fuses when I got the direction right. Worth the effort

i tried it both ways....noticed zero difference.
