Some evidence, Exhibit A
from long time Synergistic Research dealer’s website,
"Synergistic Research has a new, ’top of the line’ addition to their highly regarded fuse lineup: the BLACK Fuse.
For best performance, fuses should be installed one way, listened to, and then reversed the other way to determine best sonic orientation."
to recap, the RED fuse is supposedly non-directional (according to SR?) by virtue of the special RED fuse only treatment that realigns the crystal structure or some such thing. We can come back to that claim later. The BLACK fuse on the other hand IS directional, but not marked for direction, apparently not even using the S and R approach, so the user must try it BOTH WAYS to see which way sounds best. Make sense?
Exhibit B - the same dealer states for the RED fuse:
"For best performance, fuses should be installed one way, listened to, and then reversed the other way to determine best sonic orientation."
So, is that the dealer’s suggestion or SR? You be the judge.
