Thanks for the input you've been putting in recently on the various threads concerning fuses. You do try a lot of them. 👍
With my Kinki EX-M1, I'm getting performance way beyond what my Marantz has and it has the Brimar fuse, which I found to be very neutral and extended. I've yet to check and see what type fuse came with the Kinki.
I think going even further in clarity and extension would be for naught and that a hint more body and weight would be worth a try.
Once my new ICs break in, I think I'll give that Supreme Cu fuse a try.
All the best,
Nonoise
