The Dan D'Agostino Momentum Preamplifier
The Momentum preamplifier ($32,000 in silver, $34,000 in black) incorporates much of the technology Dan developed for the Momentum stereo and monoblock amplifiers. The unit on display was silver (a black-anodized version costs $2000 more), and includes 6 inputs, color-coded source-selection pushbuttons, and a large rotary volume control that serves as the rim on the front panel's meter. The meter shows signal levels and can be switched to show the level setting of the volume control. The power supply is built into a separate subchassis that can be seen if you look under the front panel.
