The cables are a changing. I was told last night by the person who recommended them to me about 150 hours to sound their best.
I as well experienced a narrower soundstage but not until about 20 hours or so. A tad softer now. Kinda like the Alan Maher affect but not that extreme Could the AM devices play a role in break-in ? [ I have noticed several times now that changing anything seems to go backwards for a few days and then OK ] Initially when first inserted neutral with zero issues. Now, forming. The bass is still focused and tight. No hardness, Hi Fi sound or exaggerated sibilance so far on top. Tom your findings surprised me. I heard them in two top systems with no ill affect. Time is on your side. PRAT is spot on as well. The toes are a tapping. Getting VG separation between instruments with depth. Width not yet. The tonality of the midrange is what lured me in. Midbass more prominent but not over emphasized. Berry berry nice.
Tom did you separate the conductors ?? Forgot to mention that.
Makes a difference.
I'm burning them in 5 hours on 5 hours off a day. I'll give them one 24/7 burn in between. To my surprise the 5 hours off 5 hours on has been the most affective way to speed up the burn in. I used to leave the sucker on for a week 24/7 using a burn-in disc. No more. The dielectric must be able to form and the 5 hour method makes that happen sooner. Just cannot remember where I read that.
Anyway, having fun trying hope you do too.
