· McintoshMC2300 MC-2300 300/300 Power Amplifier Amp for Audio Sound Excellentcondition. McIntosh MC-2300 is a solid-state poweramplifier which was built by the American high-end audiocompany McIntosh, and sold between the years 1971 and 1980. It canbe utilized either as a 300-watt-per-channel stereo amp, and was rated by itsmanufacturer as being able to produce this amount of power continuously, withvery little (less... than 0.25%) distortion. McIntosh's ratings were conservative,however, because like many of their amplifiers, when bench-tested the MC-2300has frequently been found to produce an even higher level of clean power.As such, it was ideal for use indemanding, professional applications. Most famously, the improvisational rockband the Grateful Dead employed 48 McIntosh MC-2300 amps as themain power source for their enormous public-address system, the Wall of Sound. Designed by Owsley "Bear" Stanley and others, this system utilized morethan 26,000 watts of continuous power fed into JBL and Electrovoice speakers,and was renowned for its natural, low-distortion stereo sound which carried for600 feet without significant degradation. TheWall of Sound was only in use from March to October 1974.In terms of McIntosh "family lineage" or productionorder, the MC-2300 was immediately preceded by the MC-2105 (with blue meters)and the MC-2100 (without), which were both 100 watt-per-channel stereo amps(200 watts monophonic) sold between 1969 and 1977. Before these came theMC-2505 (blue meters) made between 1967-1977, and the meterless but popularMC-250 sold from 1967-1979, both of which were 50 WPC stereo amplifiers (100watts mono.)The MC-2300 was succeeded by the even more powerful MC-2500 (500WPC stereo/1000 watts mono), sold from 1980-1990; and then the MC-2600 (600 WPCstereo/1200 watts mono), which was available between the years 1990-1995.Several specially-modified versions of the MC-2300 were producedby McIntosh for the United States Navy (with 6, 25, 30, 64, 120, 182, and 256ohm outputs), for defense contractor Sanders Associates, and for acoustical consulting company Bolt, Beranek and Newman (the MC-2300E, with 50, 100, 200, and400 ohm outputs).Item Condition:Well Maintained, fully tested.
