I have always bypassed the speaker protection fuses on amplifiers, with the exact same response quoted by that P.S.Audio guy, as I do not remember his name. Why should I ?, because he does not know how anything works. Kidding, of course, about not remembering Paul's name. The first and foremost reason that manufacturers use fuses, is for protection, and safety. The inexpensive, and basic Bussman or Little fuse, does this particular job well. The supplied 16 ( maybe 14 ) gauge power cord, same thing. Most of us remember the absence of the iec inlet on products. Tube manufacturers, ime, never include the most expensive tubes. They do not use the most expensive isolation feet ( these are examples )...These are all offered as aftermarket items, and the manufacturers leave this to the buyers. Never the finest capacitors in speakers, and other gear....Products, are manufactured, always meeting a price point. All answers as to why upgraded fuses are not included with the gear. Enough of my jargon...Enjoy ! MrD.
