Power Cable with a "soft" top end

Audio Quest NRG-5

hi tvad:

your stereo system has changed over time. what is the context in which you observed the performance of the kubala sosna power cord ?

that is, did you attach the power cord to all possible components--digital, preamp and amp ? did you have multiple components of each genre available upon which to base your conclusion ?

finally, please define warm . as i understand the term, it implies an attenuation in the treble frequencies and a slight boost either in the upper bass or lower midrange.
warmth , as i see it is an instance of coloration, euphoic in particular.

by the way, i want to complement you on your consistently reasoned and unpolemic comments regarding a variety of subjects. you are an asset to audiogon--a voice of sanity.

MrT, I agree with your definition of warm. However, the OP asked about a soft top end, which I assume means somewhat rolled off, or with less volume than the midrange and bass.

I observed the Kubala cord on an Atma-Sphere MP-1 MK III preamp. On this particular day, we were listening to only power cords on the preamp. Other cords included: Purist Audio Dominus Ferrox, BMI Hammerhead Gold MK III, TekLine Reference.

My system is presently comprised of: Silverline Sonata III, Pass Labs XA-60.5, Lamm L2 Reference, APL Denon 3910, KAB Technics SL1200 MK 2, Benz Micro Ace Medium cartridge, Heed Quasar phono preamp, various AC conditioning and isolation tweaks.

Thanks for your kudos.

On the Aesthetix Io, Callisto, CAT JL-3 amps, Manley Ref Tube Dac, both Dominus PCs had clearly less treble energy(soft top end) than the KS Emotion. There is detail heard with the KS in the top octaves that was simply gone with the Dominus. I had Joe Kubala here one day as we one-by-one swapped my cables for KS Emotion. A week later I got 3 Dominus PCs and 1 IC and compared to many of the KS cables Joe left with me. I stayed with the Dominus due to its 3D magic but that's a different issue.

As for other PCs, the Stealth Dream and Dream State top models, every one has significantly more top-end energy than the Dominus on every one of these components. It is not even close. With so many components tried, I concluded this was indeed a signature of the Dominus design as it carried through with the phono cable compared to the Stealth as well.

The issue of warm and frequency-extreme roll-off are two different issues. Warmth can imply a peak in the mids with or without treble accuracy/extension.

hi jafox:

it has been suggetsted that the dominus cords are not attenuating the treble. while you presented your experience with dominus and kubala sosna cords, is it possible that both are extended, but that one is less exteneded than the other ?
