Why not?

My Ampzilla amps come with a custom power cord that the manufacturer thinks is the perfect match. It’s hardwired into the amplifier. Love it or leave it

My Crown Studio Reference One Amp comes with a custom permanently attached power cord that is 10AWG with a 30 amp plug that is cold welded into the amplifier by the manufacturer so you cannot remove it. They also give you a Pass & Seymour 125 volt 30 amp wall plug in the box when you buy the amp new and they recommend a licensed electrician to install a minimum125V 30A dedicated circuit, just for the Crown amp. Crown does not offer an aftermarket quality AC power cable for this amp but they do give you a permanently attached, properly designed and most importantly, a well implemented AC power cable to perfectly match this amp.

Very good point @steakster !

@soix and @holmz Funny story about that. A friend lent me a pair of MIT Terminator2 speaker cables. I put them in my system, replacing some Crutchfield generic cables, and was amazed! Clarity, texture! I was so smitten I bought a pair of MIT Terminator2 interconnects just to see if what I was hearing could be further enhanced. Sure enough, better still. Enjoyed them for a couple of months, reveling in what I was hearing. Time came to give them back, which I really was sad to do. Determined i would have to get a set of my own. Replaced them with the old cable. Everything still sounded good. I could not find fault with the system.

@bruce19

1. Those MITs have an actual box on the end of them with a Zobel network filter
   1. They measure different as well as sound different
2. Speaker cables carry more current than any other part of the system, and are often long,

I would be very surprised if they were not different than, say, a lamp cord.

 

@holmz Ah, I see. You don’t trust your own ears. Got it.

I certainly do not trust them to make a decision on a cable after a 250 mile drive up to the shops that sell them, and know how it will sound in my room... With my speakers and electronics, and the power where I live, relative to what the power is in the shop that sells them..

 

You and @ghdprentice would have an interesting conversation as two scientists with polar opposite views on cables.

We are sort of trying to have some of that here.

 

Why not just try an aftermarket PC just to see/hear for yourself? What are you afraid of

Mostly blowing through funds, but it could be social signalling that I am not a sucker. Most of the social science types say that we do things without knowing the real reasons why we do them. So I am open to possibilities there.

 

— that your comfortable and convenient world of theories and measurements might implode if your ears tell you they’re hearing actual improvements? Or maybe you won’t find any improvements or maybe even decreased performance. Either way, that’s called learning — a concept I’d think a scientist would embrace

What you describe is not “learning” so much as its is “experiencing”. What would I have learned?

It is a somewhat more common theme to want to know why things work the way that they do. And also to have theories and laws to describe it’ll, so as to be able to repeat the process.

Would could probably make an analogy with wine. If the SO and I are having a certain meal, I know that the Tempranillo or Grenache will be great with it, from experience. I am not exactly 100% interested in how the ph and tannins, etc. combine, but if I was a vitaculturalist I probably would be keening interested in that.

And the same people consistently produce the drops year on year, and can explain how they do it.

 

Would you, or anyone else, agree that:

1. That the power supply stability/stiffness is primarily what we want to be as stiff as possible?
2. As the power supply capacitance gets larger and large, that the DC voltage would be more and more stable?
3. In my case, running off of a battery would be the more preferable option as opposed to a putting those funds into a power cable?

 

 

@thyname

Do you remember @almarg? (RIP) He was a widely respected audiophile in our Audigon community. With a doctorate in EE, he had been awarded several utility patents over his career.

He believed that technology progresses - from anecdotal to evidentiary. His approach was to try to figure out the ’why & how’ variables might influence sound quality. It was a fun for him. Like solving a mystery - or a puzzle

He sounds like he was an interesting and likeable fellow.

I make am probably not so gracious, but I’ll try:

1. If one wants to avoid spending heaps of time and $ on ICs, then they may want to consider XLR/balanced equipment.
2. If they want to avoid spending time and money on speaker cables, then may want to consider running mono blocks (with short speaker cables) and using amps that drive complex loads easily
   1. and consider using speakers that are easy loads to drive.
3. If they want to avoid power cord dramas, and power grid concerns, then they may want to look for manufacturers that claim that their systems do all the filtering and supply, and have have “overbuilt” power supplies.

I cannot imagine that a cord that is connected on an expensive outlet, into and expensive input on the amp, would be better than using the same cord attached directly to the amp in a captive sense.
And also wire nutted directly to the incoming wall power.

it is not a vacuum cleaner, where we want to move it room to room.

All those extra interfaces are places for trouble, and outlets that grip better, with no corroding materials have an advantage, as well as inlet power connections that do the same. They are just a lot more complicated and engineered than a captive cord, and they try to get back what is lost by not using a captive cord… or at least not give up any more ground.

To which you reply…

What you describe is not “learning” so much as its is “experiencing”. What would I have learned?

Wow. Just…wow. If you’re saying you can’t learn through new experiences we are truly on different planets. I’ve learned a helluva lot more by keeping an open mind and listening to lots of different equipment than I ever learned by looking at measurements. At this point I’ll take @thyname advice and just give up as there’s clearly no point going any further with this and leave with some Pink Floyd lyrics that seem appropriate…

The bleeding hearts and the artists make their stand
And when they’ve given you their all
Some stagger and fall, after all it’s not easy
Banging your heart against some mad bugger’s wall

I ended it with a question… which was, “What would I have learned?“

It is like going to a magic show and seeing a trick. What do I learn there, from that experience?
I do not really believe that the fellow saws the woman in half, and then she is put back together. And I certainly do not believe that I should try it at home.

I have no idea how he did it.
I only know that magic tricks seem real.

So what would I learn with the power cord? That it seems to work?
I would still not know how or why it works, or if is more ythan psychology.

 

Listening to some power cord, is not like riding a bicycle, or learning to ski, where the experience is learning.
With a powercord, we cannot have someone watch us from the lodge, or at the velodrome and ourselves and everyone else can all think together, “that person can ski (or ride a bike).”

With the power cord all we have some testimony that someone believes it works.
So we know that “they think it works”… in their place… with their gear. But that does not tell us if it work on our gear, with our place in the power grid.

It would be like the bicycle rider talking about the feeling of wind through the hair. But if we have not felt it, then how would we know?

If we can see them riding, and we can see their hair blowing, then we can more easily believe that their hair is being blown by the wind from the riding. And we also know how to ride, then their feelings are something that can empathise with or otherwise understand.
