I received my Sigma NR V2 and Sigma XC a couple of weeks ago. But even with the KPIP treatment, they still need a good week + of burning in before settling. The good thing is that the changes during the burning in procedure is much smaller than in previous generations like the Sigma HC and the Anaconda series[emoji6]

Looks great Mike
I have received about a week ago a pair of Sigma NR V2 to feed my Devialet dual mono.
They are beautifully finished indeed.
i did a few other changes at the same time so it’s hard to isolate their impact, but overall they seem to have contributed to an even more neutral sound without any limitation whatsoever but that of the recording on the entry side and of my room on the delivery side.
The Devialet and Wilson Benesch being as close as it gets to ideal components, my expectation of the cables is to take as little as possible from that perfection, and I feel that the V2 have gotten me closer.
cheers,
bernard

I also received my Venom V10 and 12 NR's last week -courtesy of an excellent dealer deVAAudio in Kansas -top service for Shunyata -Kudos there been running the Cardas Burn in
disc for a week as well as leaving some dynamic Classical on repeat. The sonics still show slight "glare" on upper mid lower treble compared to my previous NBS Statement cords I sold
but the detail is as I remember and the bass is more "fuller' but not boomy. I'm hoping the wee edginess I noticed will evaporate after fuller burn in of the PC's --they are the only thing changed in the chain. Impressed with the finish and presentation of the PCs.

We have all four cables breaking in right now. Will start the critical listening in a week. I did give a quick listen to the Omega XC on my Denali 6000s/v2 last night. Positive early impressions. Our Everest 8000’s arrive late this week, early next week. :exciting:

Bruce: according to Shunyata, they do not recommend any burn in treatment after the KPIP process - Other treatments may destroy the effect of the KPIP process - you should only play music.

Agreed. After KPIP, simply play music. You CAN use the adapter Shunyata has provided me to plug them into a lamp, fridge, freezer, etc. Myself? I just play music.
Really is that in the brochure / manual /blurb /etc?--Um OK--I music it is --
Maybe the damage is already done after 4 days of sweeps /tones/ etc on repeat
Woe is Moi!

Bruce,
There is no damage done to the cable by playing any CD or music source though your system. What our warning is about is using “cable cookers” to “burn-in” the cables. These are external devices that you plug the cables into. They vary in exactly what they do but most send pulsed square waves or other waveforms often at high currents through the cable. Shunyata Research cables are treated with our proprietary KPIP process that conditions the cable. These cable cookers may screw up that conditioning in such a way that the cable will no longer perform to its potential. The only way fix it would be to send the cable back to us to be reconditioned.
Second warning: DO NOT subject any of our cables to cryogenic treatment. Especially harmful is what some call “full immersion” cryogenics. Essentially you are placing the cable in liquid nitrogen. The proper method to cryogenically treat items is to use a computer controlled system that lowers the temperature a couple of degrees at a time over a longer period of time. This avoids “thermal shock” that can and does damage all types of materials including metals. Cryogenic treatment was originally designed to treat steel drilling bits and then expanded to other metal tools and engine parts. Although cryogenic treatment, when done properly, may not cause visible damage to a power cable or signal cable, it can cause long term consequences. Specifically it causes changes to plastics and extruded dielectrics that may cause them to crack or age prematurely. Any use of cryogenics in our cables voids the Lifetime Warranty.

I break in my cables by playing music. It sounds great at the start, and then at some point it really sounds fantastic.

Ah!- Thank you Caelin for the reply -- I seriously had no idea using one of the many "burn in discs" commercially available, could be harmful but as you explain
it's the Cable Cooker that conflicts with your treatments--I presume you would not be on Alan Kafton's Xmas card list anymore--
!!I did own one once I must admit --but no longer-probably saved my cables a trip for reactivation/etc
. Anyway all noted and playing some Beethoven on repeat --sounding better and better!
Thank you again,
Bruce

As we have advised for over 15 years, the best method to burn-in power cables is to simply run AC current through them. If you want to do that without playing your audio system 24/7 or to accelerate the process, hook them up to a fan. Not a refrigerator, not a humidifier.
I have nothing against cable burn-in devices. Just don’t use them on our cables. We have our own superior process that works and is permanent.
Our customer service has received many calls where the customer reports that our cable sounds bright or edgey, “even after full burn-in”. After more questions we discover that the customer or the dealer had used a cable burner/cooker. We tell them to put the cable on a fan for 3-5 days - problem solved. Sometimes the easiest solution is also the best.
