SPL AUDITOR Headphone Amplifier Model 2911

Headphone amplifier SPL Auditor High-End class. When developing the Auditor, SPL strictly adhered to a purist concept to achieve the highest signal quality. The basis of the circuit design is the time-justified reference technology “120Volt”, which uses hand-assembled operational amplifiers operating at 120 volts. This is approximately twice as much as in all modern semiconductor circuits. Thanks to this circuit design, it was possible to achieve a level of efficiency that goes far beyond the capabilities of traditional designs. The net result: uncompromising superiority in dynamic range and distortion levels over all known analog and digital standards. In other words, nothing but sound.FP29 headphone amplifier perfect Reference German SPL2910/2911, using almost the same Circuits,layout and materials.The op-amp in the machine is not for signal amplification, just provided for stabilize operating point and protect the headphones, without any replacement necessaryAmplifier using four gr
