I absolutely hear a difference upgrading fuses, it makes a HUGE benefit to the sound for relatively little money. I've loved the Hi Fi Tuning fuses, but haven't tried the Synergistic Fuses yet.
@ fleschler - Was the 5A circuit breaker you tried inplace of the fuse a thermal or magnetic circuit breaker? Is the SR Blue the best sounding fuse you have tried?
