My initial findings on the fuses are the AMR golds are too dark and laid back for my taste in both the Wireworld main leads to the amp and digital source, and when swapped inside the amp at the the IEC inlet. Russ Andrews cryo were rubbish all around and Hi-fi Tuning Supremes arrive today.
One person's "dark" is another person's "natural" depending on preferences and rest of system. As I'm allergic to excessive brightness, anything that tones this down, without losing too much, is a good thing. However, for those who, for example, find the BHSE+009 too bright, don't expect a single fuse change to sort it all out - it's still pretty subtle, just a step in the right direction.
I'm glad you're finding some differences though - shows I may not be completely mad after all.
