New Audio Frontiers Italy opens with this realization a new product line: the Stradivari Line and the Stradivari Phono.It is a Line Preamplifier that has been designed to meet the demands of the most exacting audiophiles; the study of original circuitry and the choice of components of the highest quality make it a point of reference between devices of the category. Meticolous care has been placed in the circuit of high voltage power supply that uses a very high gain error correcting stage based on the use of a pair of 12AX7 which drives a 6CA7 as power tube. The design of this circuit has been optimized to eliminate any parasitic oscillations and maintain a costant anode voltage and a ripple less than 250 µV. The excellent filtering and the use of circuit voltage regulators provide the DC voltages to the heaters of the left and right channels of the preamplifier. The heart of the apparatus is, however, the amplification stage itself, which uses (for each channel) a first tube 5814 as amplifier followed by a 5687 as output buffer. The originality of the solutions adopted mean that you are before a device that combines the qualities of a sound smooth and enfolding, with the quickness of a very wide dynamic that gives an exceptional sound detail. The fidelity of reproduction is a further feature of the apparatus that helps to enhance the quality. It was reached a percentage of distorsion at 1000 Hz of only 0.09% with a bandwidth which remains constant (less than 0.5 dB) from 20 to 50000 Hz and from 20 to 80000 Hz within 3 dB. All this maintaining a background noise absolutely not perceptible thanks to a S/N ratio of 92 dB. These characteristics are the result of a long study design and were detected in the measurement carried out on several specimens using laboratory instrumentation HP and Tektronix.
