At the Chengdu International Headphone Expo, recently held in China, British company Warwick Acoustics introduced the Gold Aperio personal audio system, consisting of full-size headphones and an external DAC unit combined with a headphone amplifier. The manufacturer positions this kit as the ideal choice for professionals to work as reference monitors when processing, mastering and mixing high-resolution music.
The frequency range of headphones with an amplifier extends from 10Hz to 60kHz. At the same time, the system is able to provide a sound pressure of 104dB when connected in an analog way and 106 dB when using a digital switching. The earpads and headband of the headphones are trimmed with delicate sheep skin, and on the ear pads its surface is perforated for better ventilation. A two meter balanced cable made of silver-plated stranded copper with silicon insulation, reinforced with Kevlar, connects to both cups.
Headphone DAC amplifier is equipped with balanced and unbalanced analog inputs. There is also digital switching – USB type B port, RJ45, balanced AES/EBU input and coaxial SPDIF. DAC is built in the “double mono” concept and is capable of processing PCM signals with resolutions up to 32 bit/384 kHz and DSD up to DSD256, both in the DoP format and in the native form. There are also analog outputs – balanced and unbalanced, which allows you to use the component as a pre-amplifier if necessary. The output stages of the device operate in class A and are built on field-effect transistors.
Body is completely aluminum. The power supply unit of the device provides a completely separate power supply to the channels and is reliably shielded from the rest of the amplifier units.
A limited edition version of the Gold Aperio set will be released in the amount of 100 copies, and each will receive a unique number, which will be engraved on a special plate attached to the upper wall of the amplifier case. Gold in the name of the version should be taken literally — the external grilles of the headphones, other metal construction elements and the front panel of the amplifier are covered with 24-Karat gold 99.9999% purity.
The unique finish is made by jewellery Quarter, a Birmingham-based jewellery company. The Warwick Gold Aperio kit can already be ordered. It will cost only 29,995£, and it is not necessary to delay the order, given the limited offer. The lucky owner will receive the ordered rarity at the beginning of next year.
