Mine gets most of my time at home. My Af was tuned for the Auteur down to the caps, so the T4 pairs much better with the Verites, which work more for the genres I mainly listen to. Not only that but I'm not running down expensive tubes if I just want to casually listen, to the point I game through it. Brimar CV-4024s are that cheap. At this level it's about synergies. T4 goes really well with fast dynamics like focals, verites and such. Not what I would choose for something that only has midrange like a 650 - they won't make use of its strengths and the T4 can't make up for the transducers weaknesses.
