To my ears, the biggest improvement I’ve heard on my source components...streamer and CD players. The preamp and amp fuse swap resulted in very subtle improvement.
I have tested Furutech, SR Black, Hi-Fi Supreme Supreme Au/Ag and Cu. I end up preferring the HiFi Tuning Supreme Cu‘s in digital components as they slightly pushed the sound towards organic and warmer presentation.
