The Graaf GM 70 is a resolutely high-end phono preamplifier which is switchable for both moving magnet and moving coil cartridges. There are six gain options located on the rear panel and the input stage is based on two pairs of PC 9OO tubes without any use of trafo’s which is the main philosophy of Graaf since over 20 years. Gain stage and output buffer stage use a pair of 6922 tubes each, chosen for their linearity, low noise and pure musical characteristics. For vinyl enthusiasts beloved in finer things in life, the GM70 is the only phono stage option.
