The ultimate performance of the complete sound reproduction system will be determined and limited by the acoustical performance and fidelity of the transducer. \u003c\/p\u003e\n\u003cp\u003eThe APERIO utilises a new Balanced-Drive HPEL Transducer (BD-HPEL) – a symmetrically-driven variant of Warwick Acoustics’ High Precision Electrostatic Laminate (HPEL) transducer, originally developed for the Sonoma Model One headphone system.\u003c\/p\u003e\n\u003ch3\u003eInjected Magnesium Ear cups\u003c\/h3\u003e\n\u003cp\u003eMajor structural components of the headphone, for example, the ear cups, are fabricated of injected Magnesium – a rigid material lighter and significantly better-damped than aluminium and most polymers. Because the Magnesium is injected, complex and precise components that typically would require CNC-machining are possible. \u003c\/p\u003e\n\u003ch3\u003eEar Cushions\u003c\/h3\u003e\n\u003cp\u003eIn order to achieve outstanding low frequency performance, the APERIO requires a small sealed air volume between the transducer and listener’s head. The APERIO maintains this air volume and requisite air seal through key design features that eliminate air leakage, even with variations in head and ear shape. \u003c\/p\u003e\n\u003ch3\u003eHeadphone Comfort\u003c\/h3\u003e\n\u003cp\u003eThe APERIO addresses comfort by minimising weight and optimising geometry. The advanced materials utilised in the design, such as Magnesium and Engineering polymers, result in a very low mass of 405 grams. \u003c\/p\u003e\n\u003ch2\u003eElectronics\u003c\/h2\u003e\n\u003cp\u003eThe APERIO is a complete sound reproduction system, thus the electronics are optimised specifically for the APERIO headphone. Every element of the sound reproduction chain between raw audio data input (from an analogue or digital source) and output to the headphone is included and fully optimised within the APERIO electronics. \u003c\/p\u003e\n\u003cp\u003eEvery functional sub-section of the electronics has been designed to state-of-the-art standards, without compromise. \u003c\/p\u003e\n\u003ch3\u003eCutting-edge components\u003c\/h3\u003e\n\u003cp\u003eThe APERIO is a complete sound reproduction system, thus the electronics are optimised specifically for the APERIO headphone.

Dual 32-bit, 8-channel DACs are utilised – one per channel in dual mono configuration, to achieve a SNR of 131 dB.\u003c\/p\u003e\n\u003ch3\u003eInput Cables\u003c\/h3\u003e\n\u003cp\u003eWarwick Acoustics supplies high performance input cables with the APERIO.
