Chuck, respectfully, what difference did you note when you did your turntable experiment?
You're asking me what I heard more than 20 years ago? You do realize of course there are people who think we need special switches to compare cables because we can't remember what anything sounds like for more than a few milliseconds. Not that I am one of those. Just taking advantage of the opportunity to really stick it to em.
The bass was better, and there was more drive and energy. Beyond that gimme a break, it was after all 20 years ago!
also, if the notion of low draw items need less "gauge" is true, what cord would you think would be good for the Herron? Keith, of course, says he just uses the stock....
I talked with Keith a bunch back when I got my VTPH2A and he's a great guy but like all designers he goes with what he knows. Learned this so long ago. Called up Aronov audio. Thinking of upgrading caps, diodes, etc. Do not do this! We use only finest quality! You cannot do better! You will void warranty! You might kill yourself! Amp may explode! Earth will fly out of its orbit!!! Okay I made that last one up. But not by much. Went ahead and swapped diodes. Was absolutely stunned, floored, slack-jawed amazed how much better $8 worth of HEXFRED diodes made that amp sound!
So you can safely ignore all designers and manufacturers- including most especially the designers and manufacturers of power cords! Ignore EVERYTHING they say! Well except for plugs. If they say its an IEC plug, or for the EU or US, that you can believe. Not much else. Certainly not any of their stories about current, or construction, materials, any of that. Its all irrelevant.
The only thing to pay attention to is sound quality. Listening impressions. From people who actually used one. On anything, by the way. Because in spite of everything you may have heard, if they say it sounded dynamic 3D and liquid on a power amp believe me it will sound dynamic 3D and liquid on your Herron. If they say it was flat and sterile on a DAC it will be flat and sterile on the Herron. This is another BS story, that these things have to be matched to certain components. Wrong. Not even.
The only thing power cords need to be matched to is your listening preferences. Which if you like the beautifully balanced sound of the Herron you will probably enjoy the beautifully balanced sound of Synergistic Research. Simply read the reviews, and when you find people describing the sound in a way you like, go for it. That's what I do, and it hasn't failed me yet.
