Stereo Amplifier SP-993

ProductDescription:

The goal here was to implement the high sonic standard of the SP 991 mono amps in one case. Hence 24 Sanken power transistors per channel deliver about 400 W into 4 Ohm, respectively 50 W into 8 Ohm in pure Class-A operation. Switching from Class-A to AB mode is automatically carried out by the amplifier if there is a need to do so.

In order to further enhance the pure sound of this amplifier its energy supply has been divided to make the power stage work as a voltage source as well as a current source.
