Allnic Audio HPA 10000 XL NUOVO

Description 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 po

Description 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.
