The purpose of the fuse in a component is to protect it from damage if it starts to pull too much current. The fuse in the power conditioner is designed to protect the conditioner and is rated to handle the max load that the conditioner is rated to handle. But this is the sum of all loads put on the conditioner. This will not necessarily protect the individual components themselves.
it would not be uncommon for a power conditioner to have a breaker rated at 15 amps, the max of the outlet it is plugged into. It will usually also have several outlets. powering multiple components, which by definition would each have to draw less than 15 amps.
Let's for example look at my Audio Research SP-9 preamp. The SP-9 has a 6/10th of am amp power fuse in it. This means that ARC has determined that the preamp could sustain significant damage if something caused it to draw more than o0.6 amps from the wall. The 15 amp breaker in a power conditioner will do virtually nothing to protect a component that can sustain damage at 0.6 amps.
Electricity is very dangerous stuff that is only made safe to use by the safety systems designed into the things that use it. Things like fuses and chassis grounds are put there for the protection of the users. Disabling any of them put your equipment, no matter what it does to the sound puts your equipment and the safety of you , your home and your family at risk. I cringe every time somebody starts talking about it.
If anyone out there thinks that the possible increase in sound quality is worth that kind of risk is worth it, God Bless.
I personally think that messing with any of the electric safety systems in our equipment is a fool hardy and irresponsible thing to do.
Rant over.
