Description :
Since 1996, the VT100 established itself as the benchmark amplifier in its price range. In 1998 appears the VT100 MKII because of its improved dynamic swing, more refined performance, and ability to drive so many "difficult" loudspeakers which normally could not be used with other vacuum-tube amplifiers. The latest version is the VT100 MKIII that shakes up the audio world once again and assure that it remains the best-selling vacuum tube amplifier in the world.
The Audio Research VT100 is robust in bass performance, deep soundstaging, excellent imaging, and dynamics that draws the listener closer to the live music reference. It gets the rhythm and pace of music recording correctly, from the beginning of the song to the end. All of the instruments and vocals blend perfectly, revealing emotion without any hint of congestion, from the snap and pop of the snare drum to the pounding bass drum that hits you in the chest, to the driving bass guitar that you feel and hear all around you, to the four-part backup harmonies so crystal clear that you can pick out the individual voices, to the three-piece horn section that is handled with such precision and accuracy. It is uncanny how fast this amplifier responds to the music.
