We had an in-depth discussion of their testing here: http://www.whatsbestforum.com/showthread.php?2199-Objective-measurements-for-power-cablesAcuity/AQ and Nordost have been working on creating a protocol to measure differences in various audio products including power cords, resonance control and power conditioning devices. I'm posting a link to the Nordost position description for those interested. I realize this is a very controversial area, but personally I do believe synergistic cabling, resonance control, and power conditioning provide a foundation to optimize the sound of a well thought out audio systemhttp://www.nordost.com/downloads/New%20Approaches%20To%20Audio%20Measurement.pdf.
When one moves out of hundreds of dollars for cables into the thousands, unless you intend to use your cables as tone controls, they are scams IMO.
If you want to use them as tone controls, then they will be the most perfect ones you can buy and will not change much over time...ie until you change the source or load component they go between.....

tomelex said:Tom here in blue: Gary, you know well that an interconnect with too much capacitance will roll off highs, and my own simple experiments with speaker cables proved that the frequency response at the amp terminals and at the speaker terminals were different and measurable, up to 0.5 db and more depending on the amplifier ouput stage configuration (zobel networks, feedback type, etc). If I used one foot of cable, then the same measurements appeared at the amp output terminals and the speaker terminals....its that simple, (a longer cable had more effect than a shorter one)the cable does affect frequency response...but I will look to your thread as well because I think we are just talking symantics here.

Yes, we are talking semantics here. I started the other thread as much as a response to this thread (but hopefully less controversial) as it was to explore our own limits of hearing with the systems in our homes. There will be others who will argue that 0.5dB is not "tone control" (I'm not one of them) and below the error of the frequency response of a pair of loudspeakers.
I liked this engineers stuff that someone else found and posted on WBF in another thread...it should be a sticky I think.

Thanks! That was a very interesting read!!
Tom, cables cannot be used as tone controls (unless they are heroically badly designed) because the FR will be flat to the limits of audibility and the phase shift will also not be audible. They do something else. If you want to continue to use this argument, I suggest that you come and participate in my Cable Dialectic. I promise you that you will spend no more than $80 for speaker cables, and they will be the most perfect ones you can buy.
I agree there's too much emphasis on "theoretical/technical mumbo-jumbo" and baseless skepticism on forums including this one. We should be centering discussions on what we actually hear when we listen to audio gear. There's also far too much emphasis in review magazines and forums on new gear rather than discussions regarding how a solid system foundation (room acoustics, system setup, power conditioning, synergistic cabling, resonance control) is crucial to optimizing the audio listening experience.
Hey LenWhite, I have been experimenting with resonance control since the 80s when Modsquad introduced the TipToes. (...)
Nice to read you post about resonance control - another audiophile challenging subject. As my equipment is mainly tube I also have some interesting findings to report. May be we should start a thread on it that does not carry the tittle "scam"?

In the end, it boils down to awareness and money to spare. If you have both you can buy the best and not worry about 0.5dB (I dare anyone to hear this) and tone controls.
Hi,
In the end it boils down to money to spare makes sense to me. Awareness is more like preference the way I see it. There are plenty of folks here who enjoy talking about what they hear and so you will have good company to keep. However, why did you then have to make a comment about something technical such as daring someone to hear 0.5 db? You are now talking what you claim as theoretical/technical mumbo-jumbo, and in fact very recently someone posted they can hear 0.5 db changes! So, when you hear something sounding better to you, then that is your preference, and others could agree or not, given we all have different hearing and ear/brain interfaces and systems we listen through, and I agree that unless the conditions are duplicated exactly (equipment, room, electromagnetic sprectrum, cables, blah blah) what you hear in your system is only somewhat transfereable to what another one hears in their system with say that cable you tried.
I am just saying that if you don't invoke specifications or measurements, as you did above, you will not hear back from the technical mumbo jumbo crowd!
Anyhow, as Gary said, he started a more technical thread for those of us (I am technical by nature) who also enjoy that part of the hobby to come play in.
And, yes, some do worry about 0.5 db, because if one starts with a source that is plus/minus 0.5db, then a cartridge that is that (we wish), then a phono amp that is that, then a preamp, then an amp, (we are now at plus or minus possibly 2 db) then the affect of the cable to the speakers and then again the speakers and then again the speaker room interface, you might have great sound, but not accurate sound. Some folks want accuracy to the recording, some don't, but no one denies that 3db of frequency response is not audible on music, when a comparison is made.
Talking about sound none of that matters, and I know that. But when purchasing equipment, one might want to know some basics, as "technical mumbo jumbos" do add up as I said.

And those who think that cables under $100 are as good as the ones for many thousands of $ should know that they are not audiophiles — or maybe they are — but haven't "tasted" the good stuff out there — HA
Hi
Just speaking for myself here . Your last statement is provocative t (the thread itself is so) .. How do you define an audiophile? It would be interesting for me to understand your definition before embarking in a discussion about the merits of expensive cables ... The answer would not be OT since you seem to equate an audiophile with someone who can find increasing value in cable with increasing price .. Can you elaborate on this please ?
For the record I have been for many years in Audio, more than 40 years, started in my early teens and have gone through the best cables up to when I changed my opinion on the subject of cables about 4~5 years ago ...
Waiting for your reply
