The HPA-10000 Features:
● True OTL/OCL (Output Transformer Less and Output Capacitor Less) Circuit. The OTL/OCL circuit eliminates the potential for any coloration or harmful time delay problems caused by transformer and capacitor coupling devices.
● Application of Advanced “Negative/Positive Feedback Cancellation Circuit. The cancellation circuit is the most critical factor for optimal operation of an OTL/OCL amplifier. Allnic has perfected this circuit design.
● High power output. Outputting 10W/50ohm, the HPA-10000 excels at driving low efficiency, planar-magnetic headphones.
● True 61-step “Constant Impedance Attenuator” (CIA). The HPA-10000 uses Allnic’s sophisticated, difficult to make, precision CIA, which we consider superior to any other type.
● Fully vibration-isolated first-stage tubes. The first stage tubes are fully isolated from noise-causing external vibrations by Allnic’s in-house designed and manufactured “liquid rubber” tube damper sockets.
● True OTL/OCL preamp output available.
● Remote controlled volume and input (5) selector.
