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.......

All of the fuses you have listed will change the sound of your system. I do think you would be most happy with the Synergistic Black fuse. It is more money than the HiFi fuses but the improvement is substantially greater. 
The 30 day trial or just send them back makes it easy to give them a listen. Return postage will be less than $10.00. Give them 24 hours to open up and 150 hours to completely settle in. So install,  leave the equipment on  and make a final decision at the end of 7 days.

 Paul McGowan of PS Audio has stated at his website that fuses do make an audible difference. I certainly heard a nice improvement upgrading the fuse in the PS Audio Direct wave Transport and also their DAC.

I have replaced the original fuses on my three different Pass Lab amplifiers with the Synergistic Research Black fuses, and in each amplifier their was a significant sonic improvement. I have since upgraded to the SR Blue fuses but there is a great price to benefit ratio with the Black fuse.
 I have tried the Isoclean, Hi-Fi, Padis, Furutech, and SR 20 fuses and all of these fuses make a small difference. The Synergistic Research Black and the Blue fuses have a much greater and better effect than these other fuses I have tried.
I have spent several hundred hours comparing fuses and the above is a simple and condensed summary.

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.

I am impressed with how my Pass Lab amplifiers and my PSAudio DAC improved with Synergistic Research fuses. The PSAudio web site has instructions on how to take the top off to get to the fuse. Easy to do when you follow their instructions.

The Pass Labs fuses are near the A/C outlet in their own screw- in fuse holder. The models are INT-60, HPA-1, andFirst Watt 7. The PS Audio fuse is inside the component. Paul McGowan of PS Audio has stated he wished they had made the fuse accessible from the outside, but the internal fuse location was picked before he personally became a believer in audio grade fuses !
