Kimber 12 TC
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.
thanks for the suggestion.
the only speaker cable i am aware of that is sufficiently rolled off in the treble, is an early purist audio design. it is rather expensive. i believe it is either the maximus or collosus.
most of the cables in production are not designed to deliberately attenuate the treble.
fortunately i have found an interconnect that accomplishes the same result.
