We're kind of tempted to just let the pictures do the talking here. The original version. Very hard to find, built like an absolute tank, once the go-to for pros now a cult classic.

Liner Notes
Crown's first 75 WPC stereo amplifier was the D-150. It was introduced as a smaller version of the beastly DC300. Crown advertised the D-150 as having "performance equal to the famous DC-300." It was optimized for studio monitoring and high-end home Hi-Fi use.
