I am an authorized Synergistic Research dealer since May 2023, but as an audiophile I have used SR cables, fuses and accessories since 2016. I started on black fuses, moving to blue, orange and purple.
Blue fuses were wonderful, much better than black in dynamics/punchlines and details/resolution. In my opinion, SR got it wrong with the orange, which added too much bloom and got in the way of details. The purple is definitely back in the right direction, with even better dynamics and details than the blue, but also with a level of effortlessness that is not fatiguing, regardless of how many you use. Before I became a dealer I was very hesitant to move to purple because of the experiences I had with orange, but I am glad to now have mostly purple and some masters in my system.
