The Audio Research Reference 750 SEL is a development of the well-known Reference 600 SEL model. The amplifiers use a very serious set of lamps - 16 x KT150; 1 x 6550WE; 1 x 6H30; 2 x KT150 Driver; 1 x 6H30. The company promises amazing linearity and musicality, as well as the ability to handle any loudspeaker - the claimed 750 watts (with peaks up to 850 watts) of power are provided at low speaker resistance from 4 to 16 ohms.
