??? Fuse UpGrade??What Size???

@emergingsoul -

     There’s a fuse holder, next to the 2301’s IEC PC socket, on the top/rear of that amp.

                            Yes: that fuse can be easily upgraded.

     Two fuses also reside on a Printed Circuit board, within the amp.

      Those are harder to get to and you'd have to experiment with them, as regards any sonic benefit.

                                               Happy listening!

Fuses are important. I wouldn't vary from factory spec. 

Does anyone seriously believe that the makers of high-end amps or whatever would cheap-out on the freaking fuses knowing that by doing so they would be seriously diminishing the sound quality of a product that they had spent countless hours developing and testing? These fuses are an insult to common sense. BTW, I heard that by painting the purple fuse red you double the width of your soundstage. Geez.

No one is suggesting they cheaped out but that doesn’t mean there isn’t one that might be better.  Same goes for crossovers components in speakers.
