Fuse upgrade from factory.....


I currently have a Theta Dreadnaught 1 5x200 amplifier which uses a Buss MDA 15amp 250V fuse. My 
Preprocessor is a Primare SP32HD with a T2amp AL 250V. I want to upgrade the fuses to maybe an S.R blue/black,  Furutech, Audio Horizons, Brimar Audio. 

 I have also read to raise the fuse rating by .25 - .50amps. 

Can anyone direct me with the better choice for my two pieces......Thanks in advance.......

Don't mind koost. He's a First Watt nut job. By the way, the very same recording engineer bought a First Watt amp some time ago and said it was one of the worse sounding amps he's heard. 

All the best,

The Cable Company is excellent to do business with. If the Black fuse does not achieve what you want, they will take that fuse back without any problems.

how complicated is it to change fuses on the Pass amp and pre, and the PS Directstream gear ? Thanks
