A discrete JFET such as TI’s JFE150, when followed by a bipolar op amp such as the OPA202, does offer a way to achieve high input impedance and low noise with flexible biasing ( Figure 1 ). Figure 1 The JFET pre-amplifier closed-loop circuit facilitates low noise with flexible biasing. Source: Texas Instruments.

Discrete Power Amps - AVS Forum

Most AVRs use discrete amps. All it means is each channel has it's own dedicated amplifier. Typically it's own expansion board for each channel. Some really cheap receivers have a single amplifier on a board for all 7 channels. I don't think so. A single channel amplifier cannot supply 7 speakers with unique signals.
