Vinyl is back with a vengeance among hi-fi enthusiasts. The sound of vinyl records is something very special and cannot be compared to the sound of digital audio sources. In this article we present a high-end phono preamplifier featuring four special opamps wired in parallel in each channel to achieve extremely low noise. We used this approach earlier in a design published back in 1982, with discrete transistors at that time.
