gold plated RCA plug: brass or pure copper chassis

Each plug will have it's own sound. In general, copper will produce a warmer sound, IMO it can also limit the upper frequencies. Gold platting is usually necessary because copper by itself will probably corrode. Best to try and see what you prefer for your ears.

It's not just the material, but the design also plays a big role

Take a look at ETI bullet RCA'S - aka Eichmann Bullet

I use the silver version and found the to be the best I've used to date

I use the Onix 70024 with Nanotec #207 wire and think they are great for the money. I also have the Xhadow RCA on a separate #207 cable and have A/B'ed them.

The Onix have a copper signature - smooth and detailed. Very natural and no glare in the midrange. The treble is good but not the utmost in extension.

The Xhadow have a little more impact and pop. The bass is a bit more defined and louder. They initially sound "better". But after a while comparing on different music I determined that the Xhadow is a bit bright in the upper midrange, which is what gives it that pop.

I also directly compared both cables to the Audioquest Colorado XLR (my Oppo BDP-105 has both outputs) and they sound very close in performance, but not quite as natural and dynamic. The Onix-Nanotec combo is 1/10 the price thought.

I also compared against the Vampire 800C on Nanotec #201. The Onix/207 combination sounds better.

The bottom line is they are cheap and sound good. I'd give them a try. I actually think they are made by Neotech as they are very similar to the DG-201, but I cannot confirm that.

Also if you can't tell, I love the Nanotec #207 cable. It smokes anything in that price range I've tried.

@Jtisher, thanks for the response. Did you fabricate these cables or have someone do them?

Thanks,

Scott

I've ended up with KLEI Copper Harmony cables from all my sources to my preamp and Furutech 126(g) between my Audio Refinement Pre5 preamp and Multi5 amp running in two channel mode and using Mogami 2549 wire.
