Hi-Fi Tuning gold fuse on Parasound


I picked a pair of Hi-Fi tuning 5A fuses for my Parasound HCA 5 channel amp (only for the front channels). After giving some burn-in time, I noticed the fuses add an extra brightness to the sound. This makes the sound a little forward. But this adds a sense of realism and dimension. Does anyone have experience using these fuses on Parasound gear.

No experience with Parasound but I had just the opposite result with the HiFi Tuning Silver Series on a Chinese Classic 6.1: it tamed the stridency while becoming more transparent with tighter mids and bass.
The Classic, no doubt, needed more improvement than your Parasound, but who would have guessed?
The sonic characteristic of a fuse inserted in the wrong direction is overly bright or harsh, relatively speaking. If the sound seems overly bright then perhaps the fuse(s) should be reversed.
The fuses have burn-in time of around 20 hrs. I tried reversing the direction. In one direction, the high end just opens up at the expense of mid base giving an unbalanced sound. In the other direction, the mid range and dynamics are very good, but the high frequency is tamed and has a silvery tone to it. I tried the stock fuse, it sounds good on the entire frequency range, but has more grain/noise compared to hifi fuses.
