cal9127 I am not instigating, per se, but I was looking for a spontaneous answer (just received from willcycle), that for the method I had used to determine that on my amps, which have one computer chip per channel that regulates the power supply, to finally satisfy my curiosity, while confirming what I thought was true, which is: If you have a power supply that is designed with a lot of overkill, and this supply is highly regulated by (only) limiting current to the filter caps which are much larger than necessary, fuses make no difference whatsoever. Thanks to Paul from PS Audio, who inadvertently made me able to figure this out, when in one of his videos, he said that we should not turn our amps off, because of the heavy surge of electricity that floods the system and creates electronic wear. My amps do not do that! Thanks Paul! For my amps, which have a 500 watt transformer and 4 26,000 mf filter caps per channel, fancy fuses (tested by shorting the fuse blocks) do not matter at all. I am just surprised that his amps do not have this design feature. COMPARISON: An early Bryston 200 wpc amp has two 4000 mf filter caps per channel. My amps are 125 wpc (@ 8 ohms; 250 @ 4; 400 @ 2), with six and a half times that, AND have a totally regulated power supply. For now, I will state that I have seen no indication that fuses matter on a well designed amp. FYI, my Bryston did sound a bit better at loud volumes with the fuse blocks shorted. It also drops a lot of bass at high volumes. The Audires do not, except for one I bought used that had the filter caps changed to 12000 mf x 4 per channel, instead of 26,000 mf. Audire did eventually make better amps than mine, but mostly by at least doubling my 6 output transistors per channel. They were 100 wpc, class A, and 200 wpc, A/B, in the same chassis. Their power supply is the same (Except for an early version that used the Audire 100 wpc amp's single 1000 watt transformer).
