Hookup wire for tube amplifier?

Wondering what kind of of hookup wire you guys have used and which you liked best. I'm considering OCC copper wire...the VHaudio OCC wire with Airlock seems interesting. Most have described OCC wire as very smooth but with detail, even a little dark. But I prefer that over bright.

I tend to stay away from silver wire just because IMO it's a gamble. It can sound too bright and tonally thin sounding, although detailed. But if you know good silver hookup wire, I'd be interested. I find the Duelund silver hookup wire intriguing.
