Further burn-in should prove beneficial, since detail and coherency via the Furutech FI-11M(Cu) AC plug are among it's best attributes. However, you might find the silver plated Furutech FI-11(Ag) IEC connector along with the unplated Furutech FI-11M(Cu) AC plug will provide what you seek, since it's a tried and true AC connector combo.
You might consider using the gold plated Furutech FI-11M(G) AC plug and gold plated Furutech FI-11(G) IEC connector for a DIY VH Audio Flavor power cord project, since they are the entry-level Audio Grade AC connectors recommended by Chris VenHaus for use with his Flavor power cords. BTW, the Flavor power cables were influenced by the Belden 83802, but the Flavor designs omit the tin plating of the conductors in favor of bare copper, which simply sounds better than tin plated power cord conductors, IME.

I'm really hoping that these open up and get sme more resolution, because honestly, I feel that the gold fi-11 had more air and articulation. Granted my gold fi-11 have years of use on them.Still, I can't help but feel that my system has taken one step forward, two steps back. I have more tonal bloom, but that's about it. I tried to listen tonight but was uninterested. That's not good. they only have about 72 hours on them, but they sound hermetically sealed. I don't recall my golds ever having this kind of affliction. I thought these were supposed to have greater clarity and detail than the gold plated ones.
I would have thought that even prior to burn in, that these (cu's) would have shown more resolution. I can't imagine burn in contributing enough to give this plug a chance at surpassing the gold at this time. Hopefully they will prove me wrong. I'll be patient. 72 hours is not enough time to make judgement- but these are my initial impressions.

For what you seek, the Furutech FI-11(Ag) IEC connector is what you should implement. I'll be quite surprised if you're disappointed after giving it a try...
Cheers, Duster
UPDATE!
Something I had forgotten about. My fi-ll golds were treated with full strength progold gl100. The metals had been burnished really well with a q tip, leaving no residue, only a smooth as silk finish, similar to freshly detailed car.
I just repeated the processes with the copper plugs. I felt the virgin- from the factory plug, and while it appeared clean and smooth, there was no denying that after the progold treatment, the prongs were slightly shinier, and smoother to the touch. The qtips did get somewhat discolred, but nothing substantial obviously being new; and full strength progold is not that strong of a solvent, but more of a conditioner.
After plugging back in heard a distinct improvement, sounding very reminiscent of the golds. The sound cleared up considerably, and that grityness that had me worried is very much reduced. Now the highs, while still not as extended as the broken in golds were, are now sweet, and reveal much more information in the lower regions (12-14khz) than before, but still not up to the golds airiness yet. The bass has not dropped yet and is still missing that very lowest octave, giving the image good weight like the golds, but that midbass gives a sense of tangibility that the golds just don't have. I do however now feel that breakin could be the dominating factor with these plugs, while before I thought they might have been a lost cause.
I had no idea how integral the progold was to my sound. There is definitely a need for it with my system. The plugs without it just didn't sound that good. Forgetting the progold was truly a folly this time. Who would have thought! Now I can get an even fight between these mains plugs!
Anyway, let's continue with the break in!
It's likely Furutech's anti-corrosion treatment layer on the blades where they make direct contact with the contacts of the AC outlet are at issue. In regards to the Furutech FI-11M(Cu) AC plugs in my collection, the blades have a bare copper interface with the contacts of the AC outlets, since the AC plugs have been plugged-in and removed countless times over the years. Simply cleaning the bare copper area of the blade with CAIG DeOxit cleaning solution does well to avoid oxidation build-up, while the anti-corrosion treatment layer protects the rest of the blade that does not make direct contact with the AC outlet contact. You might consider further gentle removal of the anti-corrosion treatment layer on the rather small area at the tip of the blade that makes direct contact with the AC outlet contact.
Thanks duster,
Do you have any experience with furutech bulk cable, i.e. The alpha 3? I want to stay unshielded, (I've taken off all the shielding of the 83803) and I've read that the tinned copper doesn't really help the sound. Would this be a signifcant upgrade over the belden? It sure as hell is more expensive......I can always get the silver iec down the line as well. Just brainstorming.
Thanks
I built a Furutech FP-Alpha 3 power cord terminated with Furutech FI-11M(Cu) AC plug and FI-11(Ag) IEC connector for a fellow inmate, and liked what I heard when placed on a power amplifier. It's been advised that the FP-Alpha 3 is best suited for power amplification or power line distributor/conditioner applications rather than source components.
