The Model 2000 Stereo pre-amplifier offers excellent specifications, outstanding sonic performance and a unique "Ambience Circuit" designed to retrieve out-of-phase signals while using the 2000 in a stereo mode. Prior to this time one had to add another amplifier and an additional set of speakers to utilize such a system, but this is not true of the ambience system in the 2000. When listening to a record played through the 2000 with the ambience circuit on, you will hear instruments that would not be audible on our preamps. The music is on the record out of phase and the 2000 corrects that problem
"In measurements made at CBS, the Model 2000 proved itself a strong performer. In neither channel did output clipping occur at less than 12,2 volts, whether driven singly or together. At an output level of 2 volts (more than enough for full output from most power amps), harmonic distortion was less than 0,02% in all cases - well below Phase Linear's 0,1% spec. And if we ignore as inaudible all harmonics above 20 kHz, harmonic distortion is no more than 0,0066%"
"The Model 2000 is as super in the listening as it is smooth in the handling. Once one has become used to the controls, they are convenient to operate and satisfying to touch. The extra flexibility in the tone controls (the separate knobs for each channel, as well as the variable turnover points) delivers worthwhile options."
