I used to think pricey interconnects were snake oil...

Let make this simple.Try kimber d60 digital cable vs monster cable see if you can hear the difference? Or Nordost try vs anticable.

No, not going to pay stupid money on cables. But there are some really good cables to be had, not cheap but a definite improvement. Cables matter.

It is evident by experiment that cables can make a difference...

I bought my Morrow interconnect three because i was unsatisfied of my SYSTEM , I was not unsatisfied by my past cables as such at the times but by my system qualitative impression... I want an easy upgrade and did not know what to do first ... I experimented it with the Morrow and "i dont even remember the name" of the few cables i compared it with ...The Morrow at 100 bucks pleased me...

No need of a doctorate in science to experiment it...No need to ask Heinseberg to prove it ...😊 The ears are if we study psycho-acoustic able to detect acoustical informative quality WHOLENESS no simple physical instrument can detect and NAME... The timbre perception for example is a psycho-acoustic and acoustical concept irreducible to pure physical measurements of any kind...It is a subjective-objective QUALITATIVE phenomenon....

Sound is not a mere atmospherical simple physical wave, we can detect BUT as claim in an ecological auditive perception theory, sound is  ALSO a  REAL INFORMATION created by the vibrating sound sources and any interference with it...A cable is something acting electrically but also physically ( copper is not silver for example )  upon the audio system "vibrations" through the speakers/room...This action is perceived as a new quality, negative or positive quality according to the specific ears filters of the owner and according to the state of his actual system/room and according to his peculiar audio learning journey...

But i bought the upgrading Morrow cables which made a sensible small positive difference FOR ME BECAUSE i did not know anyway  what to do FIRST to improve my audio system at the times...

When i had learned how to embed properly , mechanically ,electrically and acoustically my audio system , the improvements became HUGE not small as changing a cable ...

Then i never tought again to upgrade any cables...Because the ratio S.Q. improvement/cost would be too high to do it...

Conclusion : Cables matter but are secondary upgrades if they are basically good as the Morrow 3 interconnect is now for me at a relatively low price proportionnated to my system cost...If we know what to do with a system we dont invest in cables generally, and when our audio system is optimized, it is already so good, we dont invest in costly cable for a small improvement...

My remarks are valid for people with a limited budget and acoustic knowledge not for Bill Gates infinite budget..

We must learn how to listen by acoustic experiment not by buying cables...

Cables matter. That said, the biggest upgrade worth having is simply to buy a good grade of cable engineered for what is needed, and that does not have to cost a lot of money. Once you get past the basic stuff that comes free in the box, and move to a connection that covers all the basic of conductivity, shielding, durability, etc then the benefits of going past that are truly minimal. You can't go beyond the laws of physics and electricity no matter how much hype you add to the product :-) Good cables matter.
