A little story to add some perspective on this thread...
Several years ago Kent was invited to my home. Why? He and I had a disagreement over at the Asylum (I no longer participate due to what I considered virulent disdain of women) on whether an ESL's power cord could effect the sound. He said no, I said yes.
I invited him to my home to hear this on the Kingsound King (can't recall whether it was the original King or King III - doesn't matter, as I've owned both and both operate similarly). The bottom line is he acknowledged that he heard the obvious distinction in operation between different power cords. It was tough for him to admit it; he inferred that it was the power supply of the King III speaker, as though it might not be a universal effect.
Now, I can't speak to the Quad, as I have never owned it or been given the opportunity to swap power cords on one. So, wisdom dictates a neutral stance, not a proclamation - as is the habit of some here - of what can or cannot happen. Perhaps the Quad operates entirely differently and would be insensitive to PCs. Perhaps not. A simple comparison of power cords would tell.
Who cares anyway? The older Quad is an also ran, a crippled speaker, like putting an 80 year old into a foot race with teens.
Since then I have had the pleasure of reviewing the Sound Lab Ultimate 545 (at the time called the U-4iA) for Dagogo.com. Guess what? It, too, is quite sensitive to power cords. Surprise, surprise. No, not really if anyone bothers to actually TRY changing power cords. If the Quads are not sensitive to power cords, then I consider them even worse than their already quite stilted performance. They would be one step away from junk, imo, as they are so compromised holistically, to add the crippled performance of not being tuned by power cords would make them undesirable as ESL speakers, imo. Frankly, I think they've been surpassed so thoroughly over time that the cult of adherence to them is more from nostalgia than superior sound. They were an amazing product many decades ago. Now? Hardly. Having heard them several times I wouldn't dream of swapping out the King III for them. They aren't even in the running for SOTA sound.
I have no interest in debating/arguing my position on this.
Phillyb, is the smart one. He actually tries things, and realizes it's a waste of time listening to people who don't. :)
