JRN, I agree completely that Flux take an inordinate amount of time to break-in. Anyone who shortshrifts these wires because of what the do (or do not do) during the first few hundred hours of operation, will waste their time and their money. Flux deserve a lot of patience to give their best. I have used the completeFurutech Flux suite for perhaps 1500 hours. My findings about this remarkable series are in my PFO article at:
http://positive-feedback.com/Issue47/furutech.htm
I have continued to use them after the end of the review process for several weeks , and the wires still blossom further for an additional couple hundred hours.
However, after inserting the Shunyata King Cobra CX + Auroras in the system, and breaking them in for approx 300 hours, until they stabilized, this Shunyata suite as a whole has become my reference cabling. As wonderful as the Flux series is, I found the Shunyata King Cobra CX cords, particularly when fielded in synergy with the Shunyata Aeros Aurora ICs and speaker wires, to be significantly and comfortably preferable in most aspects of my application, for the reasons discussed in my previous post. While Flux cords may be slightly more energetic than KC, which may undoubtedly tip some user's preference toward Flux, the overall sonic and musical parameters I discussed in my previous post have easily caused my preference to fall for the Shunyata KC+SAurora combination.
The single exception is a position where unfortunately I have not yet been able to isolate variables to my satisfaction:
I found the musically and sonically most desirable solution from the Furutech ETR-303 Daytona conditioner to the AC grid is currently a 12ft Furutech Flux that reaches a rather far isolated 20A outlet. Unfortunately my KC is only 2 meter long, and reaches only a standard non-isolated 15A circuit outlet.
Using the KC to power the conditioner through a regular outlet within its reach instead, the system yields a sonic environment that is slightly subpar in grain-free musicality and resolution, compared to powering the conditioner with the Flux fed by the outlet on the 20A isolated circuit.
It is worth pointing out that an isolated circuit can have a very significant effect on the overall sound. Hence, in the next several weeks, I might enroll the assistance of a friend of mine to move the isolated circuit to be in reach of the Shunyata King Cobra CX, so to eliminate the effect of the last uncontrolled variable, and perform an even more valid performance determination.
