Front Row Seat Power Cord?

Pass actually does recommend the supplied power cable...it's in the XA25 paperwork.

@laginz ,

Curious as to why you think changing your power cord will give you the result your looking for. I legitimately don't see the correlation.

Oh poppycock…. forget the psychobabble let’s have some facts. Equipment based tests have shown indisputable, overwhelming results that other than optimal size, quality, the cable industry as a whole is a farce ! Then we have science i.e. physics, credited professionals, again overwhelming majority comply with equipment results.
lastly there’s the ears, purely subjective, no consistency. Groups of enthusiasts, professionals alike can be swayed one way or the other any number of tests and times. We’ve (solely for entertainment purposes) tested factory, aftermarket, DIY cables, only to see overlaid equipment results as well as consistent inconsistent hearing results. Note; not a whole lot of high dollar cable spenders willing to test or accept the results of a/b testing out there. So begs the question why does one feel the need to give away in some cases large money for purely monkey speculation… Ridiculous.

There is only one undeniable truth about Power Cords.  That being, there are people who believe their $500 - $5000 power cord has made a difference, and those who don't.  Pretty simple and neither side is going to convince the other. What is truly amazing, IMHO, is how this topic garners the amount of member input, over and over and over again.  I'm personally in the camp that believes you should use a shielded cable of sufficient size to carry the current from point A to point B.  I don't mind spending a bit of cash as I do think the sum of all parts creates the final sound, so I don't use lamp-cord on my speakers either.  I think Power Cables are a great place to exercise some DIY.  In the end, believe what makes you happy and enjoy your systems.  Cheers.

I have given you a concrete example of a power cable radiating EMI from a subwoofer.  The EMI was sufficient to take out my TV reception, which of course is a low-level digital signal.  This is entirely reproducible, and was solved by modifying the cable by adding two ferrite chokes.  Untamed, this EMI would feed into any other connected component which just might affect its performance?

As a Cambridge-trained physicist, my natural inclination is to disbelieve odd claims. However, reports of RFI affecting sound quality have been around for decades, so maybe there is some real phenomenon at play.  Back then, everybody thought it was from the mains, so it seemed non-sensical that the last six feet could make a difference.  Much more recently, our own components have come under suspicion, especially those with electrically noisy digital circuits, or switched mode power supplies.

Rather than dismiss what people claim to hear, I would prefer to try to understand what they are reporting.  It may be psychobabble, or it may be a real phenomenon we don't fully understand yet.

Do I personally think changing a power cord can move your virtual listening position?  Never in a million years, but every good scientist should keep an open mind.  I also deplore the reluctance to do A / B testing, especially on something as easy to swap over as a power cord.
