Dual mono power amplifier with fully balanced structure
and two custom made Hypex Electronics Ncore power amplifier modules

The unconstrained dynamism of sound awakens fundamental instincts.
The AP-701 merges all the elements desired in a power amplifier at a high level, creating a new standard.

Independent left/right high-capacity toroidal core power supply transformers, discrete buffer amplifiers and two Ncore modules provide a complete dual mono structure from input to output. Moreover, the input stage of each channel has a fully-balanced design, so the dynamism of input signals is amplified as is, maximizing the innate performance of the speakers.
The cabinet is primarily comprised of 3mm-thick heavy metal plate but has a flexible structure to control vibration. By incorporating joints with suspension functions, the vibration frequency of the entire device is controlled to reproduce open and vibrant sound.

With two toroidal core power supply transformers and two Ncore modules, the extravagant circuitry has a complete dual mono structure from input to output. A dual mono structure, in which the channels are each completely mono, prevents interference between the left and right signals and achieves outstanding channel separation. This enables rich audio reproduction that provides a larger sound stage and more three dimensional sound.

The durability of input circuits is ensured by including slits between each connector. In addition, direct wiring without connectors is used from the input circuits to deliver input signals to the discrete buffer circuits without losing any of their clarity.
