Upgrading Fuses

I upgraded the fuses in my MX-Rs to positive effect. How much you notice will, to a large extent, be determined by the resolution of the rest of your system. In my case, there were 10 fuses for a cost of $450, but I felt it was worth it.

Are the fuses in the audio circuit path? Some(all should)keep the fuses out of the audio path.

Well power cords seem to make a difference, so why not fuses?
The only fuses i have upgraded are the ones in my Speakers, as they are in the signal path.

Just upgraded the fuse in my integrated amp. Didn't change the world, but did make a positive difference. Well worth the $40 spent.

They work, but it will depend on the resolution of your system to determine just how big an improvement you'll experience. Expect to be disappointed for the first few days as they, like anything, need some time to break in. I kept my system on for 4 straight days at a very low setting and from time to time would check in on it.
It went from 'what the hell is going on here' to 'that's very nice indeed'.
