My buddy Scott Warren uses the Dartzeel amp and preamp with Von Schweikert 9's, Playback Designs Cd player, MIT Oracle MA interconnects, speaker cables and David Elrod Gold power cords with Sound Applications JC-1 line conditioner.
It's jaw dropping and expensive
If anyone would like to contact him and have a listening session send me a pm. He's a dealer for all the above products and more high end gear.
