Frequencies addresses by power cords?

For example MIT and Transparent?
Not sure how to interpret the question. Can you clarify?

Say what???
PO Box 99999 Mars
60Hz in U.S..
The address for MIT is
77 Massachusetts Avenue|Cambridge, MA 02139-4307

It's about 10 blocks southeast of Harvard.
Kr4's answer is probably the only correct one possible in the US anyway.

Power cord will transmit the ac electric signal at that frequency and then the its the rest of the gear's job to modulate it into frequencies representing the sound.

Power cord itself has little to do with it beyond that I would say.
Thanks Al. Misprint. s/b frequencies "addressed".
As in what ac "line noise" frequencies do the various top line power cords attempt or claim to eliminate. Equitech "seems" to state to 100,000 hz as they mention other filters operate above 100,000.
AC in the US from the wall socket is delivered at 60 hz.
My take is that some power cords tend to deliver more lower frequencies than others,more bass sounding.
Some power cords can roll off the top,while some seem to amplify it, and sound edgy.

When I say the power cables sound bassy or edgy, I mean the gear plugged into it takes on that sound.
Because all music is, is a bunch of different frequencies.
Full range speakers will reveal more frequencies than small mini monitors.
Perhaps those with gear that don't cover a lot of frequencies are less aware of tonal shifts which to me are affected by filtering or enhancement of certain frequencies by our components and the connecting wires.
Solid core wire "sounds" different than stranded copper, silver sounds different and different guages or thicknesses sound different, as do different wire configurations.
Even so, it should be easy to hear the differences in power cords, wires, with mini monitors as with full range speakers.
Clarity can be enhanced with different power cords, could that mean that more frequencies are flowing thru one cord as opposed to the other?

I tend to feel that, all components really do is alter the frequencies of the music.
And music is just a bunch or frequencies, strung together in a pleasing way.That's why we like some gear and hate others.
We like the stuff that pleases our ears and the frequencies we are comfortable with.
We don't want highs that lead to fatigue and we don't want sloppy boomy bass frequencies.

All of us, over the years,have developed a "house sound"and anything that deviates too much from that comfort zone isn't loved for very long.

We tend to replace one thing with another that does the job better than the last.
Some time we do scrap it all and start over, but we do develope sonic memories over time.

In other words we know what we like, we just want more.

If you beleieve all power cords sound the same,or more correctly, can't alter the sound of what they are connected to, then none of this makes any sense.

Amazing how that 60hz of electricity can be persuaded to give us so many more freqencies to enjoy isn't it?
Ptss, AC power cords have to have some bandwidth because quite often a lot of the power is delivered at the peaks of the AC waveform, in the form of a spike that is actually a much higher frequency than the AC waveform itself.
Thanks Atmasphere. Interesting. I thought the distortion didn't contribute much to the power output. In fact I thought ac distortion was a negative factor. I've seen so much about using REGENERATION to provide a smooth waveform and therefore more usable power? And I thought all conditioners were basically working towards this goal. By the way I don't think ac power supply is going to improve anytime soon. any thoughts?
Ralph's comment isn't referring to distortion in the incoming AC voltage. He's referring to the current drawn by the component, which can (especially in the case of power amplifiers) consist of spikes of high amplitude lasting for just a small fraction of each 60 cycle period, with little or no current being drawn during the rest of the cycle. The brief duration of the spikes means that their frequency content extends to frequencies that are much higher than 60 Hz, and the bandwidth of the power cord has to be high enough to avoid significantly attenuating of any of that content.

So there can be a tradeoff between maximizing noise reduction and satisfying very rapid changes in demands by the component for current. I have no particular quantitative feel for what kinds of bandwidth numbers tend to be optimal with respect to that tradeoff (which btw will also be affected by the house wiring).

Well Al, what does this mean for power regenerators?
I don't think that any generally applicable conclusions can be drawn about power regenerators. From both a technical and an anecdotal standpoint their efficacy figures to be dependent upon their own design, the designs of the components they are powering, and the characteristics of the incoming AC.

Obviously regenerated AC that is essentially free of both noise and distortion figures to either be helpful or to not make a perceptible difference, depending unpredictably on the designs of the particular components and on the characteristics of the incoming AC. But whatever limitations a particular regenerator may have in terms of its responsiveness to abrupt changes in demand for current may or may not outweigh that benefit, depending on the designs of the components and the regenerator. And adding to all of that uncertainty is the possibility that the potential downsides of either using a regenerator or not using a regenerator, if present to some degree, may be subjectively preferable to some listeners with some systems.

So it's all essentially unpredictable as I see it.

Safe comment - unpredictable :-).
MIT and Transparent both use "Interface Boxes" which are nothing but "glorified" low pass filters that filter most signals above 20KHz.
Thanks Don, more detail would be helpful. I'm most interested in MIT, Shunyata & Equitech. (These mfg's don't provide detailed specs; although I can't imagine why. If they are proud to build it--they should be proud of what it does.(High-end has had enough "magic" & "flooey dust"-not to mention "magic anti resonance dots-wow, that's a great one) over the years and I am certainly hoping our tech advances will soon make "magic" a thing of the past.) I want to create the most effective "blend" of conditioners and power cords. Of course I'm doing well by ear, thanks to Ref Spectral & MIT gear-and an Equitech 2Q providing a basic isolation/cleaning of AC, creating adaquate depth of detail and clarity to analyze the sound I have, but in classical music I enjoy how more details bring me closer the the artistic creativity of the composer, the director and the individual genius of the players, not to mention the ambiance and silences.
