Cryo or anti-cables at 10.00 a stereo foot.

Acoustic Zen Satori or better yet satori Shotgun if you are setup to bi-wire

very resolving, tonally balanced
you can pick up a pair used here quite often

Some interesting choices here Mr. T.
Cardas is an expected recommendation.
I also agree with the HT Pro 11 and would add Pro 9+.
I would stay away from silver plated copper.
The Anti-cables should also be alright but given your inclination towards things vintage, why not try single runs of Jupiter solid core copper in cotton wire. I would consider their 16awg for single runs and maybe 16/20awg if you are biwiring. You could also consider their 6x26awg (twisted together = 19awg aggregate) 6-nines copper in cotton. Don't mistake the clarity you hear for a lack of warmth.

Van Damme Total Definition Directional HIFI or Vann Damme Blue Series. These are cheap compared to typical HiFi brands and sound outstanding. After using them in your system you may like myself think that spending more on speaker wire is silly. Van Damme products born from studio market like Mogami
