About the A-48S
Accuphase A-48S is a high-end pure Class A stereo power amplifier with a 6-parallel push-pull MOS-FET output stage, designed for very high damping factor, low noise, and linear output into difficult low-impedance loads. It remains listed on the manufacturer’s current product pages, so it does not appear to be discontinued.
