About the MA6450
The McIntosh MA6450 is a high-fidelity stereo integrated amplifier produced briefly from 1998 to 1999, combining a 100 watt per channel power amplifier with a sophisticated control center. It features seven high-level inputs for various sources, Power Guard to prevent clipping, Sentry Monitor for output protection, and iconic blue watt meters. Similar to the MA6400 but without phono preamp and headphone output, it includes remote control (HR033 or HR093), bass/treble controls, tape loops, and processor loops. This model is no longer manufactured and is sought after in new old stock or used condition.
