GRAHAM SLEE - GRAM AMP 3 MC ONLY PHONO PREAMPLIFIER

GRAHAM SLEE/GRAM AMP 3 MC ONLY PHONO PREAMPLIFIER

The new Gram Amp 3 is dedicated MC phono stage in one box with an outboard power supply. It uses studio tape-head preamp technology to bring you the extreme fidelity captured in the groove. By designing a high gain phono stage for only lower output MC cartridges (0.2mV-1.0mV), Graham Slee has avoided the problems associated with many of the MM/MC designs. The input impedance of the Gram Amp 3 Fanfare is fixed at 470 Ohms which was found to present the optimum load for the vast majority of lower priced moving coil cartridges. The Gram Amp 3 has designed the perfect, affordable MC phono stage with the correct gain required, super low noise, low distortion and the level of performance you deserve.
