I bought a Leben preamp from Pitchperfect and Matt was dealing and using auditorium in his dealership. He had Shindo, Leben, and Line Magnetic as the primary line and auditorium was his connection of choice.
It was more than I wanted to spend and I ended up with Triode Wire Labs and am extremely happy with the result. They are used usually in conjunction with Border Patrol (tubes) and Volti audio speakers. Triode offers a try it before you buy it so you can see if it will sing in your setup and I have returned some Triode so know from first hand experience that there will be no issue or problem if you do decide to pass. I use Triode power cables , phono cables, and interconnects and am gradually going the loom route with Triode. I have not tried or used their speaker wires and still use and greatly enjoy my anti-cables speaker cables with my stats. I have used generic, Zu, and another speaker cable that can't remember and the anti-cables work with my stats best. I have both horns and stats and plan on Triode Wire lab speaker cables for at least the Horn system and then shoot em out with the Anti's and see what happens.
I think if you got ahold of Auditorium and Triode Wire Labs and did your own comparison you will be playing in the right ballpark. I sure would be interested in what you prefer and why.
