McIntosh fuse changeout to make better sound

As all the power that goes into the unit flows through the fuse, why wouldn't it matter to go from a thin piece of tin/lead to something better? 
Anyway my experience has been that every time I've gone from stock to SR or Audio Magic or Hi-fi Tuning fuses the sound has gotten better. And that's whether its tube or solid state equipment.
As far as your question on which one, I've used SR red and blues with good results on my sources and haven't bothered to upgrade. On my tube monoblocks I'm using Audio Magic ultimate premier's and love 'em.
As other's have noted in this threat, just be careful to match the values on the tubes you're replacing. 
Good luck and enjoy!!

Well UCDMAC you asked an interesting question a year-and-a-half ago and were told yes fuses do matter, no fuses don't matter and everything in between. Did you ever try any fuses in your system? If so what's your opinion?
