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


 In an effort to maximize the potential of my SimAudio Moon 240i integrated amplifier I have decided to try one of the Synergistic Research Purple fuses...
 The owners manual states it uses a 4 amp,Fast Blow,Type AG fuse..
 However,there are 2 sizes of this fuse offered,5mm x 20mm & 6.3mm x 32mm..How do I determine which size I need? Pulling the old one out & measuring it comes to mind but I was hoping there is a faster way to determine this...
 Thanks very much for any assistance..

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.

     When the steam locomotive came on the scene; the best (scientific) minds proclaimed, "The human body cannot survive speeds in excess of 35MPH."

      Until recently (21st Century); and the advent of the relatively new science of Fluid Dynamics, the best (scientific) minds involved in Aerodynamics, could not fathom how a bumblebee stays aloft. 

     Often; Science has to catch up with the facts/phenomena of Nature and/or, "reality" (our universe). 

     I haven't been in school since the 60's, but- at Case Institute of Technology; the Physics Prof always emphasized what we were studying was, "Electrical THEORY."  He strongly made a point of the fact that no one had yet actually observed electrons (how they behave on the quantum level) and that only some things can really be called, "LAWS." (ie: Ohm, Kirchoff, Faraday)   

                         PERHAPS: that's changed in recent years and I missed it?

Hi Gregory,

          Thanks for your comment concerning a second Rel S510 subwoofer. I had bought 1 a couple of weeks ago and found a noticeable improvement in all aspects of my SQ. Was very concerned about my neighbours downstairs, but never got any complaints so sometimes overthinking can stop us from moving forward. I decided to call my dealer and he had one more left at an incredible good deal since I bought the other one. That 20% missing is subtle but there.There is more coherence between the music and instruments. I can say, it’s like I was waiting at the gate of heaven and now I stepped inside for good. Thanks, just thought to share my experience with you,🎼🎹🪕🎻
