Copper vs. Silver interconnects


We are running two systems from one CD player. We have a SET (tube, obviously) amp, a hybrid (tube outstage) amp, and the CD player also has a tube. I love my Verastarr silver reference interconnects, but it's always fun to try out different cables.

I have listened to a variety of copper cables (Kimber, DH Labs, Analysis Plus, Harmonic Technology, etc.), and I find them to lack the clarity and lively authority of the silver cables in these particular systems.

My question is this: do I stick with the silver cables (or gold, palladium, beryllium, etc.), or are their some copper interconnects that would really be worth trying? I'm asking for your collective expertise/experience on this one, as I don't want to continue going through the process of buying and selling cables that are only going to sound veiled and/or dull in comparison to the Verastarr's.

Thank you for the input.

Since your SET has quality output transformers, I'd expect that you don't need to overcome any high-end rolloff by using silver cables.

I use the all-copper Sonoran Plateau cables in my system with a SET amp, and feel very happy with them.

I work for Starsound, but I don't have to personally use any of their stuff if I don't want to. The Sonoran cables sounded just right in my system, after trying several different kinds, including DIY stuff. They had a very good neutral sound, and the price was in a range I could afford.
FWIW, I was using a AZ Silver Ref II from CDP to preamp and I purchased an Au24 to compare; I found both to be very close to one another but chose the Au24. Both are fine IC's IMO.
Audience AU 24's are outstanding. IN MY SYSTEM I preferred them to numerous highly regarded silver cables.
I've been thinking about trying the AU24's, as I've only heard great things about them. Thank you all for the feedback. All of the cables you mentioned will be on my list to try.
All the best,
Howard
