I2S Recommendation

I now have a good amount of hours on my Veritas Optimus 100 I2S cable. Using it between a Denafrips Gaia and a Denafrips Terminator 2 in a headphone rig that I am still building, so rotating out amps and headphones to figure out what I like most.

I do think the Optimus beats my previous favorites which were the DH Labs and the Voodoo Cables Silverstream. It just sounds more open and alive than the DH Labs, and more fully fleshed out than the Voodoo. They are all great cables but in this system the Veritas is is clearly the best match, I can easily recommend it especially for the price.

Tried quite a few others from Audioquest, Kimber, Wireworld, Analysis Plus, Cardas, and some others I am forgetting. Lots of models were just ok, some were pretty bad (I'd rather just do USB instead), and a few were decent but too expensive. I would rank the Veritas as my top pick, followed by DH Labs and Voodoo in second and third place respectively. All great values in my book. 

I understand that cable quality is influenced by material properties such as the dielectric, but the conductor material itself is also critical. Do you know what the Veritas Optimus 50 or 100 I²S cable is made of—silver, copper, or silver-plated?

@lanx0003 Sorry I don't recall seeing that info about the Optimus cables. You'd probably have to ask them and see if it's something they are willing to share.

Now that I think about it, I don't really notice any trend as far as which materials sound good to me. I like the AQ Vodka and Thunderbird (both silver plated copper) much more than the higher priced Firebird which is pure silver. I didn't care for the Wireworld Platinum Starlight which is pure silver, but I also didn't really like the Nordost and Kimber models I tried which use silver plated copper. 

Come to think of it, my three favorites from Veritas, DH Labs, and Voodoo, actually don't specify what they use. Voodoo uses the name "Silverstream" but never tells us what materials it is made from. And DH Labs uses the name "Silversonic" for all their products, even the pure copper designs. So who knows at this point?
