My First DIY Power Cable

You can call it whatever you want "burn-in" / "break-in".  It all means the same thing.  Trying to talk down to someone because of your opinion on the "correct dictionary term" is not someone who I can respect. 

Additionally, rhodium can be the great revealer, in the sense that it is very revealing and will reveal the flaws you have in your electronics and cabling.  These are flaws that gold-plating or un-plated copper will NOT reveal because they are ultimately more forgiving.  If you are not liking the rhodium in your system, it is likely that a particular piece of equipment is causing that sonic signature.

Can a system sound good with gold or unplated copper?  Sure, absolutely.  But you are never going to get 100% full transparency, resolution and realism that you will with rhodium plated connectors.  I have been through all RMAF rooms and different systems from $10,000 on up to $200,000 and even the million dollar room.  Pretty much most of them use gold-plated connectors and silver-plated.  I will say that many (if not most) room did not hit the mark on a good high resolution real sounding system (even systems that were 6 figures). 

Choose whatever you want and whatever feels best to you. 

@auxinput +1 With all the resources at Furutech's disposable they have good reasons for using Rhodium but usually offer an identical product in gold.

Personally I've found Beryllium Copper (Oyaide) to be the sweet spot between the two. However some components still favour Rhodium.

OK you win. I don't know what you won, but you won. Rhodium is great.. Do you mind if I keep my red copper, silver over red copper, pure silver, or gold over copper or silver. I'll keep my speakers and equipment too. Just saying I use to go to the shows because I was in charge of equipment there. That's where I met most of the guys I hang out with. We were mechanics but I loved music too. I was into car audio competition too. My kids suckered me into it. I was tired of fixing alternators and adding batteries and all the thing kids like..

They love rhodium, they didn't care either. Just what it cost.. Spoiled kids with horrible hearing.. Systems were PRETTY though. But mine sounded better and won the competition usually at 1/10 the price.. Sound doesn't come out of a spray can or pricy parts. It comes from YEARS of listening and pleasing my ears. The strange thing is most of the people I know have come to the same conclusion. Were just mechanics. What the heck would burn-in mean verses burnt up.. Not a single thing.. But neither term has a place where professionals are involved. 

For fun maybe.. I'll stick with williewonka (I have for years) and people that make cables that work better than most, not good, or good enough, but BETTER. 

Rhodium and HiFi, ok if you say so.. I can't hear that nugget to save my life.. I guess the other 20+ guys are not hearing thing too. Strange my wife can hear rhodium through small planars, all the way down to the wall plug. Smart lady, copper and silver all the way.. She does like a tungsten construct that I don't care for. Good ears with expensive taste in cables..

Not sure what would be the appeal of Beryllium Copper as an audio connector/conductor.  That copper alloy is usually spec’ed when hardness, strength, and corrosion resistance is needed. I had a set of Beryllium Copper golf clubs (irons) once.  However, wrt conductivity, Beryllium Copper is less than 50 percent IACS.
I find it interesting that some claim to hear differences between oxygen free copper wire at about 100 percent IACS and OCC copper wire at about 101percent IACS, and yet have no issues using connectors that have nowhere near the conductivity of any type of copper - I chalk it up to either weird audiophile lore or, maybe an indicator that this stuff doesn’t make as big a difference as we would like to believe.

@mitch2 ding… I think you win the prize with your last sentence!! Are there variations in materials, use, signature etc? Sure. But, everyone thinks their opinion is the best. To their ears, probably is. It doesn’t really matter, it’s all a big pissing match anyway. Regardless of the connector type, materials used etc, if it sounds good to the person listening it’s all good. I do believe pure copper to be the basic go to when it comes to cabling, particularly power. It is tried and true, and the Furutech copper connectors are great for starter DIY. Wire? Same thing. Pure copper. Gets one in the game, is generally easy to work with and produces a really nice cable if done properly. Getting into the esoterics of plating etc. is a matter of preference, not necessity to be explored as knowledge and experimentation develop.
