Can hi-end cables benefit less expensive electronics?

Modest is the word except maybe cabling for TT. They can be much more sensitive and certain better made cables can help. Though we should all graduate from zip cord and cheap rca’s.

@jpwarren58 In relation to creating a Signal Path for a Cartridge produced Electrical Signal, to undergo Amplification, experience has has shown in relation to Phono Cable and Amplification the following items when used has been substantial in how the End Sonic is presented.  

Solid Copper Low Eddy Connectors used on both Cable Termination and Chassis along with a Silver content Solder will be a very good starting place to learn exactly what a Wire Type can bring to the sonic being produced. 

When the Wire Type of choice is discovered, extend the use of this Wire Type as a hook up wire for the amplification devices that enable it to be used. 

Thank you all for the precious input. A very interesting discussion for me, and I'm humbled by the fact this is/was one of the most popular threads on Audiogon. I never expected that. If I buy an expensive digital coax (Metronome seems to favour coax), I will certainly add an honest opinion on whether this has been a change for the better, or for the worse. I'm tempted by the digital cable upgrades for two reasons, to be honest. Of course, I have some hopes of adding some sophistication to the sound of my digital setup, which doesn't really need adjustment sound-wide (and my other cables are already "hi-end" price wise and offering improvement, or at least not making things worse..). Here this stems from my belief (and intuition! ) that the digital link is really important and still not appreciated enough. The second thing... is my desire to own something special people rave about ;-) The second point might come to you as a surprising confession. I live in Poland, where money has always been an issue more than in most other places. As a student, I read about all those expensive brands people own, dreaming that one day I might also be able to afford it.  Now I know the price is not indicative of quality, but I guess I still have this desire to own something I could not afford in the past, even if this defies logic... And I always wanted the best ;-) I'm currently considering Transparent Digital Link XL or Siltech Golden Eagle Double Crown, both of wich I can get at nearly half the retail price. Admittedly, it's an effect of audiophilia nervosa... I am aware of it. Somebody suggested Audioquest Carbon as a good choice - I had this cable once and it was a really good cable, but I used it only to connect my Mac to the DAC in Metronome CD8. Not sure what I'm going to opt for in the end, but I will certainly let you know. It's quite likely I will victim of my "being-poor-in the-past" dreams... I hope this is legible, because English is my only second language. 

The above serves as a clarification that there are also personal psychological factors involved in my considerations... 

But overall, I guess this is a very interesting discussion, because there are many cable topics everywhere, but not much discussion particularly in the context ot buying top-of-the-line cables for not-at-all-top-of-the-line components. I really appreciate all the response I'm getting.
