A stupid question(s) about power cords

@immatthewj As Eric Squires alluded to, the value of a 3-Wire plug into the wall will offer the connection to earth ground necessary to provide a shield for the cable. Whatever cable you buy, every manufacturer I’ve seen on record recommends a shielded cable. You can’t have a shield without a connection to an earth ground. The purpose of the shield is to provide a path by which to ‘drain’ EMI (electromagnetic interference) present in the environment from other electromagnetic producing components like transformers, speakers, other power cords which aren’t shielded. In your case it may be an advantage that there is no third pin on equipment, as it prevents the condition in which the shield is connected at both ends, which some interconnect cable incorrectly do. If the shield is connected to ground at both ends, it is no longer a shield, but a conductor.  (Although, in deference to Ralph of Atmasphere, it all depends on the implementation of internal circuitry.)

So, the two pins on the equipment end means that they have isolated the equipment from earth ground. My understanding is that this is an older, and some say better, way of making equipment safe. These days everyone has jumped on the GFCI (Ground Fault Circuit Interrupt) bandwagon, which requires an earth ground connection as an alternate path back to the utility. Regardless of the method, the purpose of fault protection is to carry the current back to the utility, without going through your body. 

l hope your new power cable enhances your experience of the music in your system.

@audphile1 There is one big thing you missed in your list. Maybe there are no differences? That could be a possibility also.

That list was classic audiophile bullshit and arrogance.

I missed nothing.
You can call it whatever. The list is 100% accurate. Post pictures of your system. I’ll prove it to you.

Ignorance

@audphile1 , I suppose that to be honest I do fit into a couple of the categories on the list. Although, with all things being relative, my equipment is probably okay, my room is small and acoustically untreated and I am near-field listening (unobstructed equilateral triangle) which I have read on this site may take the room somewhat out of the equation. And I suppose that it is possible that I either lack the ability to hear all sonic changes or I may lack the ability to realize that I am hearing all the differences.

However I would say that: I did make a couple of equipment upgrades in the last four years (the SA10 that was kind of the driver for this thread and a SLP-05) and I was able to hear the differences, particularly with the SLP-05. Also I will say that I have been rolling some pairs of 6SN7s in the balanced input sockets of the SLP-05 and when I put a real nice pair in there, I definitely do hear it. Also, with good source material in the SA10, the sonic effect works magic on me. As an example, last night I played three discs that I liked the music on: the Sony SBM (redbook) remaster of Born To Run sounded like nails on a chalkboard, the MFSL redbook of Goodbye Yellow Brick Road sounded better on certain tracks but overall not a whole lot better, but when I put the MFSL/SACD of Cowboy Junkies Whites Off Earth Now . . . as I typed--magic. I wish my oldy but moldys could sound that good.

So with that last paragraph typed, I am not completely devoid of the ability to hear, and I’ll just have to see/hear how it goes. I’d also say that way way back in the days when I upgraded speaker wires and interconnects, I do not remember being slapped in the face with an "OMG, that sounds better!" but I do know that I felt a contentment when I was listening that drove me to listen longer and more frequently. Of course, I have no doubt that my hearing was better back then.
