THE RESULTS ARE IN
AGAIN
I completed the A/Bing of the various fuses in my possession.
-------THE METHOD-------
--For the preamp (an extensively modded Meridian G68), the contenders were: stock fuse vs. Hifi Tuning Silverstar vs. Isoclean
--For the amp (a Pass Labs XA30.5), the contenders were: stock fuse vs. Hifi Tuning Silverstar vs. Furutech
--All fuse endcaps were first cleaned with Cardas contact cleaner. I was careful not to touch the endcaps when swapping fuses.
--Nearly everything electronic in the house was turned off. House lights were turned off. Air conditioner turned off. Very little ambient noise at the time of the test.
--The amp was never unplugged during the test. The preamp was unplugged for each fuse swap, because the fuse could not be accessed otherwise.
--Down time while swapping: 45 seconds for the preamp, 30 seconds for the amp.
--Fuse direction was noted during every swap.
--Volume was never changed.
-- 3 auditions of each fuse in each direction
--Music used: 1. Jai Deux Amours on Careless Love by Madeleine Peyroux. 2. LEstate 2 from Vivaldis Four Seasons, Drottingham Baroque Ensemble, BIS Original Dynamics Recording
-------THE RESULTS-------
The preamp fuse winner is
Isoclean by a nose! The Isoclean fuse had slightly better resolution, imaging focus, and overall naturalism than the stock fuse. The stock fuse was better than the Hifi Tuning Silverstar in those same categories.
The amp fuse winner is
a tie! The stock fuse and Furutech were indistinguishable. And boy did I listen close. Both were better than the Hifi Tuning Silverstar, which had a strange phasiness, as I reported in an earlier post, and heard again in this test.
AND ON THE DREADED TOPIC OF DIRECTIONALITY...
I could not hear any differences when changing direction for any of the fuses. Make of that what you will. Bad system. Bad ears. Bad method. Bad attitude. I just didn't hear it.
There it is. My not-particularly-scientific experiment in fancy fuses is concluded, and I am happy to be done with it. I can now move on to more important things, like A/B'ing capacitors!
