Thoughts on Iconoclast interconnects?

Hi all. I have Iconoclast Gen 2 UPOCC RCA cables connecting my LTA preamp to my Audionet amp. They sound very transparent and neutral to me; however, in the past, I have always had XLR cables and therefore haven't tried any other RCA cables at this position of my system. It might be nice to have a slightly more enveloping and 3D soundstage with just a tiny bit of warmth. I have no doubt that AQ Thunderbirds, Cards Clear Beyond and Audience Frontrow would all be fantastic options to try, but the new retail price is a bit more than I care to spend. I am fine purchasing used.

For those that have used Iconoclast, what are your thoughts on these cables and what if any cables did you prefer to them? Would like to have some input before rolling the dice on some of the more costly options.
