Sony XA5400ES fuse directionality...

I'm afraid the above idea would cause a LOT of problems in the neighborhood, AND void my 5 year warranty!
I thank those who stuck to the idea of this post and actually offered some helpful advice. To the others...
at this point I think I am going to have to throw in the towel and call it quits because I have no strength left to fight. I confess.... I just pulled out a Q-tip for the first time in 20 years, and discovered my ears have been filled with peanut butter all this time. I can't hear anything above 100hz, and I'm selling everything but my subwoofer...but you can bet IT will have an upgraded fuse in it! :^}

Really? Which ones were those?
You do have a well thought out system though. So if swapping fuses turns you on, enjoy.

Look, I KNOW there are hundreds of things regarding music playback that have NOTHING whatsoever to do with Ohms Law, measured performance or even rational thinking. Every time I dismiss something out of hand, then hear it for myself (and notice a difference) I feel the fool, but fuse polarity has no more bearing than the North-South orientation of your system in regards to Magnetic North....(believe me there was an Apple 22 inch High Res Color monitor that had to be degaussed with it oriented N-S or it got psychedelic!!! (so even this parameter need be taken into consideration as we have lots of magnetic devices in our systems, but that is another detail I cannot worry about).

I apologize for offending your original post's spirit, and since I refuse to micro analyze my system anymore (it's awesome and I plan to enjoy its awesomeness and listen to the music), that does not mean others can abide such dismissal, and cannot further reduce miniscule weaknesses.

Enjoy your journey for further truth and disregard us old curmudgeons (I have accepted the limitations of my system/room and just love the tunes. Stevie Ray Vaughan on Pandora One as we type).

Thank you Mcintech, and enjoy your Stevie Ray as much as I do.... I think it's time for some "Texas Flood" to spin in my system too. His playing was beyond compare!
