Fuse Direction for Pass Labs Amp and Preamp

It’s funny that us audiophiles sometimes believe we understand electronics better than electrical engineers do. If DCS, Pass, and other good brands ship their products with standard cables and fuses - shouldn’t we be able to reject the urge to upgrade those?

The fuse needs go in correctly or it will blow! If you put the fuse in backwards it will suck!

It didn't take long before the trolls, name dropping and appeals to authority came up. They make very poor substitutes for actually trying them. 

All the best,

One of the things about this hobby is you can extrapolate things to the ridiculous. Fuse direction is one of them. How do you know that by switching the fuse it is the metallurgy of the fuse with respect to the AC source that makes it sound different? Maybe it's the fuse holder. If you look at a fuse holder there are two connections -- one on the end and one on the side. There is no standard (or electrical difference) which connection is from the power inlet and which connection is to the transformer. Some manufacturers wire the inlet to the side and the outlet to the end and some do it the other way. So when you change the fuse direction and hear a difference, maybe it's the way it's oriented in the holder and that is why other people hear it differently or hear a difference with the same fuse turned around in different components.

I recall a conversation I had with Ken Stevens of CAT who said if you don't have the time or patience to evaluate a tweak... then save your money.
