Personally, I decided on the material for my XLR interconnects before the brand. Here are your options:
1. OFC Copper
2. OCC Copper
3. OFC Copper coated with Silver
4. OFC Silver
5. OCC Silver
6. I heard there is OCC Copper with OCC silver coating, but, I am not sure. Same for OFC with OCC silver coating.
I have a full separate component system with monoblocks and I changed all my interconnects all at the same time, from OFC Copper to OCC Copper. I immediately felt that this was a step up in sound and really made a difference. Note: they were not all the same brand, and I bought them all used on Audiomart/Audiogon/ebay...
