I have the entire FREY array (shotgunned speaker cables, matched shotgunned jumpers, and XLR ICs)
I did not get them cooked by the dealer but rather let them open up within my system.
good news:
(1) as highlighted above, the improvements open up BUT in stages... it was not a constant steady flow. It was more series of higher steps in an ad hoc timeframe.
(2) vocal sibilance and harsh edginess (if any) in the CD and digital reproduction was slowly tamed.
bad news:
(3) it took in excess of 350+ hours (lost count) before that get-to-the-pinnacle curve started to flatten out.
(4) As the cables finally settled in, their superior resolution capabilities also now graphically highlighted all the weaknesses and warts in the listening room arena itself. To keep up with the cables performance satisfaction, a series of sequential audio improvement via room treatment exercises were commenced in a Series of tweaks.
(5) During the speaker cable baking process, my buddy and I did a lengthy multi events myriad of alternate IC swap-in / swap-out of alternate brand ICs. Our experience was that the FREY speaker cables (and overall audio performance) performed better as all-FREY array .... there was a special synergy there.
My experience: the road to audio excellence in the Emerald City in OZ was not a straight-line falling-off-a-log exercise, BUT well worth it in the end. Your patience may be tested in the break-in marathon. At their pricepoint --in my system -- they have bested all contenders and pretenders.
FWIW....
