Sugden AUDIO MASTERCLASS LA4

A high quality active preamplifier with a series of inputs and outputs.LA-4 fits perfectly with power amplifiers Masterclass or Sapphire. High-end touches include golden printed circuit boards, relay switching of all inputs and outputs and a sophisticated class A output stage. LA-4 is a high gain amplifier that provides a control iron punch on any power amplifier. The electronic circuit has been developed to offer the best possible sound performance without compromise, including the use of specially selected transistors and capacitors to provide the best signal preservation. The gain stages are each powered by current shunt differential feeders, which allow faster transients and more powerful crescendos with real musical empathy.
