... abit confused: how does a power cord affect the presentation of sound...


Hello to all...

I was shifting around components in my system, trying to squeeze out better controlled bass, more definition within the soundstage, and better define the "voice/midrange" presentation...

I presently have a tube preamp (hardwired with a wall wart) into an HT Receiver; source is a Marantz SA-8001 CD Player

Swapped out a Yamaha HTR -5550 (hardwired) for a Parasound HCA-750A (which needs a power cord).

CD Player is powered with a PS Audio Statement SC power cord, so I went in my closet and pulled out another PS AUDIO Statement SC power cord, hooked it up and expect to give it at least 5 days continuous re-break-in before serious listening.

Took a minute to lookup reviews about this power cord - and I read some rather confusing reviews: some luved 'um, some liked 'um, but some thought them " ...slow... " (?), and giving a veiled presentation...

I'm gonna listen and decide myself - but I'm abit confused: how does a power cord affect the presentation of sound - I know that interconnects and speaker cables would/could/Do affect sound presentation - but how could a power cord?

Explanation/thoughts please...

6 feet of power cord can easily affect and audio system, depending on where it is in the system.

The deal, ie, how it affects, how it happens... is about the instantaneous delta of the inductive collapse of the field integration of the complex model of the power cord, under high delta draw from the DUT.This area of draw or complexity of the signal in the given 'moment' is how we as humans, hear. 

100% of our hearing is coming out of what is effectively approximately 10% of the signal.

If you measure in engineering terms, this represents a vanishingly small amount of the signal, as it is weighted as a comparison to the entire signal.

If one, during measurement, ignores 90% of the signal, and then concentrates, or confines 'the entire measurement and comparison of signal' cycle, to the transients ONLY, then the measured distortions creep up into the many full percentage points area.

This is critical, as this is how the ear hears. The ear does not hear the bulk of the signal, it does not work with the bulk of the signal.

The ear hears EXCLUSIVELY via the transients and micro transients, and the differences in level and time, between said transients. It does not hear, acknowledge or know anything about the other 90+ percent of the signal.

So, when measuring... THROW OUT the 90% of the signal that means NOTHING to the human hearing system.

When we measure cables for differences, it turns out that the biggest area of change or behavioral differences between various cable,s is happening in the inductive transient collapse of the signal as it propagates in and via the cable.

Well, would you look at that. What a coincidence: It just happens to be exactly how and where the ear utilizes the signal.

Out of all the cable types in the world, there is one that is head and shoulders above the rest, in dealing with inductive collapse.

And that is Teo Audio's liquid metal audio cables.  It is utterly unique and different.

For example, if one tries to make an inductive coil out of the liquid metal, it fails to operate in the same manner as wire, it fails to behave like a known entity, in expected inductive behavior. It is unique in this characteristic, regarding all other high lass metallic and/or 'solidus' conductive pathways.

The only relatively similar pathway, the only relatable known pathway, mathematically and in pure physics descriptive terms..... is that of a gas.

A literal quantum response and behavior characteristic, not Newtonian.
High quality power cords do not impede power to the unit hence high impedance/low impedance with the root word being impede
if power is less impeded to the component the more stable and efficient the signal from that component will be    At least this is how it was explained to me
good luck 
Wow, the website lists no prices and no ability to purchase from there, no dealers listed or found when googled. Saw some older reviews and one forum showing some prices from 2017. Definitely on the upper end of the spectrum, but not sure which of the three series shown on their website that could have been. Liquid state is definitely different, though I wonder what the conductivity of the medium is compared to copper. 

Can we think about this logically (can we?)?

So long as the metallurgical properties of the cable are capable of carrying the AC, and so long as the size of the wire is sufficient to the current draw, then it seems to me that the ways in which a PC can affect the component being powered by it (and possibly components downstream) are two:

* the cable is acting as some kind of filter on the AC it's getting from the receptacle

* the cable is acting as some kind of shield that is rejecting some kind of outside electrical interference

What other possibilities are there?

CAKYOL+1 i hard wire my mono blocks to the mains no power cord no drfference in soumd no power cord is the best sound for audio
