WHY CABLES MATTER!

Sorry, this is a bit of necromancy here, but I have been reading this thread (and others on this forum) with great interest and have some questions.  
 

How do you know of your system is “high enough resolving”?  Do you just know?  Is it “high enough resolving” only if you can hear changes to the system when you swap out cables and power cords?  Does equipment have to be expensive to be “high enough resolving”?  Or can lesser priced equipment be “high enough resolving”?  What is it about a particular piece of equipment, say something  from Infigo……,  that makes it “high enough resolving”?  Is there something in the specifications of the equipment that will give me some clue as to whether or not it will be “high enough resolving”?  Or do you just have to buy stuff and switch it out until you think you are there?  If I measure the noise floor of my room and then turn my equipment on and it doesn’t change, does that mean my system is “high enough resolving”?  Does cable burn in only matter of your system is “high enough resolving”?

Thanks in advance, as this seems to be a fairly confusing topic.

Okay.  That was clearly too many questions.  Let’s start with the basics then, I guess.  What is the definition of “high resolving” when it comes to audio?

I don’t have a system, currently.  I’m just getting into this.  So what you are saying is that I just go buy stuff and see if it works?  That seems like a lousy way to start.  I don’t want to buy equipment unless it will be top notch.  

@rodman99999 First you say 

No one can tell you whether/how your system, room and/or ears will respond to some new addition.   There are simply too many variables.

     LIKEWISE: no one can possibly know whether a new addition (ie: some kind of disc, crystal, fuse, interconnect, speaker cable, etc)  will make a difference, in their system and room, with their media and to their ears, without trying them for themselves.

Then….

Many cable vendors have fairly knowledgeable people manning their phone lines & e-mails*, available to guide you, based on your equipment, finances and listening habits/desires.

Why would it matter what those knowledgeable people say?  I’m not trying to be obtuse here, but that makes no sense.  I feel like you are trying to sell me on these websites.  
 

So back to my original questions, but more specific:

1.  Can you name one attribute you look for in speakers that tells you they will be “high enough resolving” when researching a purchase?

2.  Can you name one attribute you look for in amplifiers that tells you that they will be “high enough resolving” when researching a purchase?

I have no idea, at this point, whether cables make a difference because I’m currently looking at system options to purchase.  But it appears that I won’t have any luck with cables unless my system is “high enough resolving”.  That is what I’m shooting for.  There has to be a way to look at these things prior to purchasing that will give me an idea of how they perform, correct?  Some of these speakers and amps weigh hundreds of pounds, and even with free return shipping will be a giant pain to return.  

So no one can discuss how you would start to purchase a “high resolving system” short of talking to “experts” at some recommended website? There is literally nothing you can look at in the specs of the various audio equipment out there that can guide me?

@dill - Why? Because I’m asking questions?

@akg_ca I don’t have a “side”.  I just want some information.  Calvin said you had to have a “high enough resolving system” to appreciate cord upgrades, and I would like to know how to get that sort of system.  There has to be some way to go about doing this.  Well, some way that doesn’t involve demoing cords from some questionable websites.  

So where I’m at now is “how much do you want to spend”, and “you just have to have experience”?  While I appreciate your response, @dill , what are you going to tell your buddy that is looking to get into audio?  Is it just, “yeah, it sucks man, but you just have to get out there and buy something and see where it goes”?  

It seems to me that a “high resolving system” should be reasonably attainable no matter who the listener is, short of legitimate hearing loss.  If the criteria include almost zero noise floor and being able to hear fingers on fretboards and people breathing behind the scenes, that should all be pretty straightforward to engineer.  Well, as long as these sounds are actually in the recording to start with.  

I am not saying anything substantial. I don’t have anything substantial to say. I am here to learn. And, to that end, I’m asking you questions, which you are conveniently sidestepping.

to be clear, Calvin, I’m not attacking you. Is asking you to sell your product to me “attacking you”? Must suck to go to work every day, if that is the case.

@calvinj 

All of our systems are unique. Listen and do what’s best for you and your system. Do your research but trust your own ears.

What does this mean?  What “research”?  I realize the best seems to be “cost prohibitive for most”, but hey, at least you can give people a place to start, correct?  Isn’t that what good salesmen do?  
 

I have yet to hear you say anything of substance, really.  Again, what do you look for in the Infigo line that makes it such high quality?  How will this brand help me synergize my cables?  What makes it better than other brands?  Sell your stuff!  Surely you can at least do that, right?
