For your consideration is an Audio Research D-450 Stereo Amplifier that has the power to drive even the most demanding full range speakers. The reviews have all raved about this amplifier!
I am selling my Audio Research front end (the ARC SP-20 is also for Sale) because I am devoting my listening time to an Audeze LS4-based headphone setup. This amp and its accompanying pre-amp have been idle and, hence, need to go.
The amp is is outstanding condition and will come with a superb Shunvata Research Copperhead aftermarket (20 amp) power cord free of charge if my asking price is met.
