The 625 incorporates many of the same technical features of the 725 amplifiers. Similar to the 725, the 625 signal circuitry is built upon a Rogers ceramic circuit board laminate material for lower dielectric absorption and energy storage.


Precision LED based current sources have been implemented throughout the amplifier circuitry, along with 0.1% thin film SMD resistors for more stable operating points and lower noise. Custom designed Lundahl input transformers are implemented
