Synergistic Red Fuse ...

  As far as the SR Red fuses being directional, are they all sounding better placed in the same direction or does it depend on the equipment used?  

I'd recommend to those who are using the Reds, try 1 AH fuse in its place and you'll hear the analogy I mentioned about thinness. You will also hear more texture and body especially with violins, acoustic guitars and cellos and also experiment with direction.

Probably time for a group buy for AH fuses. BTW AH reseller states this "If you are a former Audio Horizons customer or order of components upgrade, there is a 15% discount off the $115 MSRP...". Where do you get a lasting audible improvement for just one Benjamin?

In my tube DAC and my NAD amp I am happy with the sound of SR Red. 

/Wig: do you have any equipment with more than one AH fuse? 
/abuck: sometimes it is visible on the fuse holder (IME on most holders it is outside to inside where the current flows), it is easier for fuses inside the unit to see where the current is going to (just remove the fuse and use a multimeter to see where the end is that is live).
/mitch2: lucky you, I got 2 systems to feed. BTW is there any downside to wrapping them in Teflon? I do that as standard procedure. Also, when the WA chip still is sticky enough, I pass it down to the successor.

Very nice discussion of fuses so far. I think along with fuses the other change that can make a significant difference in the over all character of a system's sound is the A/C wall socket. I am currently using 4 Synergistic Research and 1 Furotech GTX-Rhodium duplex on my system's circuit.
I really do like the fact that Synergistic Research gives you a 30 day trial to find out what works best for your system.

Anyone use SR Red Fuses on Primaluna amps?
