Hi Vinnie,
I almost hesitate to pose this question, as I expect there are strong opinions as to whether "upgraded" fuses produce sonic benefits (in general, in various audio components) . . . and don't want to start a flame war. Limiting the application specifically to the LIO, please advise as to whether you've found upgraded fuses to be beneficial . . . or have reason to believe they might be based on your circuit design.
Thanks!
