I am using some Tara prism, but it is primarily for cosmetics--took a piece of leftover cable, covered it in black techflex weave and heatshrank the ends to keep it neat. It matches my PS Audio Biwire Supremes (in looks, not in heft), but no change in sound.
Here's my real reason for responding. . .I have used the same transducer combo (Maggie 1.6QRs and a Vandersteen 2Wq) in four homes in the last six years, and there have been significant affects on bass performance. My current listening room just absolutely defies me getting the right bass, regardless of trying levels, Q settings, etc. I've moved that sub a combined distance of three miles in the room, and have had the Maggies all over the place as well.
Conversely, in the last home I had, I just plopped the speakers and sub where I thought they'd work best. . .and magic! Never touched a level, Q setting, or moved the thing once it was spiked. Miss that room. . .!
At least from my experience, the wire has been the least of the influences. Not sure if this is what you wanted to hear, but hope it helps eliminate it as a meaningful variable.
