aftermarket fuse location


any thoughts/experience with the RELATIVE merits of upgrading fuses that lie in the powersupply path vs in the signal path, itself?  forgive me for applying "logic", as I know to trust ones ears, but it would make more sense that a fuse in the signal path would have more affect than a fuse on the incoming AC, acknowledging that AC powercords do, indeed, matter.....just interested in others experience
thanks

I have a Valve unit that has fuses in three places. Two made a difference one did not the Power cord made a difference way more than the AC fuse I couldn't tell the difference.

The other two were in the valve protection and transformer circuits, that was quite the sonic nugget indeed. I have a pair of 71.00 fuses coming we'll see if they better the SRs..

BTW, not to often I recommend a fuse, but there are places a piece of good copper or silver goes a long ways.. The problem is burning down the house if something gets sideways.. 

House breakers have held up so far.. I sure had a mess after a cable drop two years ago.. First and hopefully last.. Not a single fuse inside an amp blew, a 20 amp breaker DID.. 3 right channels failures over the next couple of months. ONE cable drop..

If you want to be logical, start with AC and the power supply being just as integral to the signal path as anything else.
