Audioquest Argent? Midnight? Sterling?AudioTruth?

I'll second every word of what Thorman had to say, as I'm still using an Argent-Midnight cable set to biwire my main speakers. I haven't used Argent in a single wire setup, but I reterminated a pair of Midnight biwires to single for lows and added Argent for highs and this was a noticeable improvement over the Midnight biwires. Hope that helps.

Thorman very accurate,the Sterling is better than
the Argent.The Dragon is the best actually.

I had Midnight & Argent combo, then changed to Sterling & Argent. Argent gives you more tonal quality right through the musical scale. Midnight gives slightly more bass weight.
But, yes, Midnight/Argent combo is very good; but the Sterling/Argent combo is better.

The difference between a double run of Argent+ and a double run of Sterling 2 is enormous, an improvement in all aspects of a given performance, night and day. The Argent pales in comparison. I tried the Argent+/Streling2 in more than one system with the same results.

Sterling+ is again a jump up from sterling2.
Sterling+ is very similar to Dragon+ in my system difficult to tell them apart when not concentrating/ listening properly.

I found that Forest+ was better than Argent+ in the bass though the argent presented a clearer mid bass and up. Naturally the upper range of argent was superior to the Forest, just more air and detail.

Hope this helps

I tried the Argent/Midnight combination for bi wiring on my Vandersteens but found that using Argent for both runs improved the bass quality over the Argent/Midnight combination. I got better sound top to bottom with the more expensive Argent/Argent bi wire set up.
