From an excerpt from a Sterophile review from April 1987 (John Atkinson, Anthony H. Cordesman):
“The Mod Squad Line Drive System Control Center is a purely passive stereo switching unit with a volume and balance control, five line inputs, and additional facilities for two tape decks. It allows the audiophile to replace a preamp, with its active gain stages—and resulting coloration—with a device that introduces no distortion or coloration other than that in the wiring, switches, and controls.
Tiffany jacks are used selectively for two pairs of inputs and one pair of output jacks. The unit uses Lorlin selector switches. Wonder Wire, Wonder Solder, and Teflon-insulated LC/OFC wiring. Construction is on the battleship side, and the styling and feel are excellent”
This is The Mod Squad Deluxe Line Drive with the superior Penny & Giles attenuator pot (one of the most important components of a passive preamp). It also features Tiffany sockets while three of them, "CD" and "AUX2," and one of the "Main Out" have the expensive WBT sockets. Simple, but well built with top notch parts and wiring from MIT and Wonder Wire.
