    Shunyata Delta NR power cord and Furutech Flux-50 NCF Filter

    Is there much or if any difference between the Shunyata Delta NR power cord and the Furutech Flux-50 NCF Filter?

    They do appear to do the same thing.

    They do appear to do the same thing.
    They do the same thing for the most part, with respect to noise reduction, but not with respect to another attribute, which I'll explain.

    Before I get into the detail, I think its important to recap what power cords are supposed to do: deliver current.

    The #1, top requirement for any power cord is to deliver current as quickly as possible when playing music, particularly dynamic content. Shunyata developed a complete metrology for measuring this, and it is referred to as Dynamic Current Transient Delivery aka DTCD. Listeners invariably prefer power cords that provide high levels of DTCD, as this functionality provides the openness, dynamism, responsiveness and naturalness that we reference back to live music.

    Now, with regards to noise reduction: there are lots of ways to suppress and attenuate noise (its not possible to reduce it to "zero", but that's an aside that gets into physics): inductors, chokes, coils, Balun and other isolation transformers, etc., have been used for long time to reduce noise. The issue with these is they can and usually do, have a signficant noticeable impact on DTCD. This is one of the reasons that generic powerstrips that provide noise reduction, e.g., the Monster noise reducing power strips sound so dark, compressed, and well, crappy, 'cause their noise filtering significantly impacts DTCD.

    What Shunyata was able to do with the NR-series of power cords (and also their power conditioners) was to able to provide noise suppression without impacting DTCD, this is why they represent a breakthrough, IMHO.

    With respect to noise reduction, both the Delta NR and the Flux-50 will provide noise suppression of AC mains line noise. I didn't own an NCF, but I had a non-NCF Flux-50, and using an Entech powerline noise analyser set to a nominal reading of ~100-110 when used with a generic black power cord, the Furutech reduced the noise from ~100-110 to ~12-9 (it's noise so it fluctuates when taking readings). A Venom 14 Digital power cord, which utilizes the same noise suppression technology as the Delta NR, reduces noise from ~100-110 to ~1.7 to 1.0.

    But here's another key distinction, and one that is important, in my view. When I installed a Flux-50 into my system's preamp and connected it to my Triton...I didn't hear any improvement...at all. Zip. I left it in for a bit to burn in, but after that, I just took it out because it didn't do anything for my system with its power distribution configuration.

    By contrast, even using a Shunyata Venom NR-V10 or V12 power cord in conjunction with my Triton (which provides about 24 dB of noise suppression), I heard a notable reduction in noise, which made the sytem sound much quieter, blacker, open, spacious, and transparent. This was compared to my Shunyata Black Mamba power cords, which are no slouch.

    Now for the Delta NR....when I installed this power cord in conjunction with Denali 6000/S V2, I heard a reduction in noise (though not as dramatic as with the NR-V10/12 using the Triton simply because Denali already provides >60 dB noise suppression). But the biggest difference I heard were really increased dynamics, speed, and ability to "scale" from piano to fortissimo, even over Venom NR-V10. The improved DTCD contributes significantly to the lifelikeness of the presentation.

    Bottom line: I flipped my Flux-50 after a number of years of it sitting unused on my parts shelf. And, I've been buying quite a few Shunyata NR power cords.

    Wow Stephen....thanks so much for the detailed explanation. I’m going to give the Shunyata Delta NR power cord a try. I have a few Furutech Flux-50 NCF Filters that I can do a direct comparison.

    I'm pretty confident you'll love it, its combination of NR and DTCD is really impressive.

    Now I have to be on the lookout for a Black Friday deal!!

    Thanks again Stephen!

    That'll be the day...I've been hanging out for Shunyata deals but they seem to exclude their digital I/C's and higher spec power cords from discounting.
