SUPRA
A super low-noise
MM/MD phono preamp
By Thomas Scherer (Germany) and Ton Giesberts (Elektor Labs)
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.
Here 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.
