No discussion about the Synergistic Pink fuse?

It is true that hearing is not listening.  Listening, like decent conversation "skills", is a learned perception.  It takes practice no matter how keen, acute, fully functioning the hearing  is, to listen to sound a person must put effort and attention to get better at hearing the abstract details.  Without practice, and especially if the person has never heard the component, all is air.  I have developed sophisticated listening skills over many years, composing, playing, and also developing a high end sound system.  No doubt the trolls will love my comments.

Fuses need time to break believe it or not.   All electronics in general, some more than others of course, benefit from burn in for 100 to 200 hours of electricity going through it.   If you have good listening skills, you will like the fuse (or component) much much better after it has time to break in.   Don't listen to people who can't sort out music or playback characteristics.   They will typically also not be able to hear a difference between a stock power cord, or duplex or even interconnect cables and the hifi higher priced kind of cables, fuses included.   

The Master fuse and SR Purple duplex were quite remarkable on my high end system.   Good luck on your upgrades.
