Hi-Fi Tunig Fuses & Parasound A21

Milpai,

Glad to see you are thinking about this upgrade. Agree with the above description of benefits in general. I realize these are a fairly spendy add-on, especially if you are replacing multiple fuses. But for the benefit I think they provide in terms of improved sound, I am surprised at least some high end manufacturers do not specify them as OEM.

Thanks again guys. I would start with the AC Main fuse first then.

Given this option for the A21 is it the same on the A51's?

Hello,
I am thinking of replacing the stock fuses of Parasound Halo A21 and have a couple of questions for this audience who have hands on experience with fuse replacement.
1. It seems to me that the main fuse which is in the signal path would be the most important fuse to replace and would yield the max improvement in sound. Replacement of the 4 internal fuses in the rails not being in the signal path might be optional. Would you agree?
2. My fuse options are Hifi tuning Supreme and Synergistic Quantum Black. I read rave reviews of Hifi tuning fuses used in Halo A21 but not so much on the new Synergistic Black fuse. Did anyone have an opportunity to compare these two fuses?
3. I tried cleaning the main stock fuse with DeOxit Gold contact cleaner and the result was a very harsh sound as if the fuse was not broken in. I have also found that the sound changes with the direction of the fuse. In one way it is relaxed with a very clear mid-range specially the voice with a little loose bass. The reverse direction produces a very fast, punchy sound with a controlled bass but it had a tad hazy mid-range specially the voice.. I wanted to get both but it is not possible at least with the current stock fuse. Did anybody experience this behavior with the direction of the fuse be it a stock or an expensive audiophile fuse?
Thanks
