Integrated amplifier with tube preamplifier and a great-sounding transistor power amplifier.

The MA 400´s integrated phono preamplifier has been constructed with very low-noise operational amplifiers, hand-chosen components guarantee a deviation from the RIAA equalisation curve of less than 0.3 dB. It is also equipped with an elaborate subsonic filter with an 18 dB/octave slope and 16 Hz cut-off frequency. The preamplifier´s selected double triode tube (Type ECC88) is burned in for 60 hours before it is fitted.

With a “genuine” continuous performance of 40 watts per channel and the delivery of a total performance over 150 watts for short periods, this integrated amplifier is also suitable for demanding loudspeakers. Elaborate and separately stabilised supply voltages as well as generously dimensioned buffer capacitors (2 x 10,000μF for the power amplifier) ensure dynamics, low noise levels and outstanding channel separation for the individual amplifier sections.
