2. Arcam and dCS have had a long and fruitful relationship that goes back to the highly innovative Alpha 9 & CD23 versions of dCS’s Ring DAC The dCS technology allows a precision clock to drastically reduce the level of jitter from USB music sources and delivers a massive improvement in sound quality over the standard USB ‘adaptive’ system.

While some of the most effective designs we’ve recently heard have been from less-than rdacc names, here it’s the turn of established British brand, Arcam to debut an affordable DAC. As it is, the wireless input light sits on the front of the rDAC, but cannot currently be selected. Arcam rDAC (£) – Outboard DACs.

Audio Stream Input/Output (ASIO) is a computer sound card driver protocol for digital audio specified by Steinberg, providing a low-latency and high fidelity interface between a software application and a computer's sound card. Whereas Microsoft’s DirectSound is commonly used as an intermediary signal path for non-professional users, ASIO allows musicians and sound engineers to access external hardware directly.

ASIO bypasses the normal audio path from a user application through layers of intermediary Windows operating system software so that an application connects directly to the sound card hardware. Each layer that is bypassed means a reduction in latency (the delay between an application sending audio information and it being reproduced by the sound card, or input signals from the sound card being available to the application). In this way ASIO offers a relatively simple way of accessing multiple audio inputs and outputs independently. Its main strength lies in its method of bypassing the inherently high latency and poor-quality mixing and sample rate conversion of Windows NT 5.x audio mixing kernels (KMixer)[citation needed], allowing direct, high speed communication with audio hardware. Unlike KMixer, an unmixed ASIO output is 'bit identical' or 'bit perfect'; that is, the bits sent to or received from the audio interface are identical to those of the original source, thus potentially providing higher audio fidelity. In addition, ASIO supports 24-bit samples, unlike Windows NT 5.x MME and DirectSound which truncate 24-bit samples to the upper 16 bits, whereas Windows NT 6.x mixer provides 32-bit floating point output. Higher bit-depth samples offer the potential for a higher signal-to-noise ratio.

As one of the very few audio specialists in the world to design AV receivers, Arcam has developed a reputation for balancing a finely honed technical specification with world class audio performance. The AVR390, AVR550 & AVR850 are, quite simply, the highest performing AV receivers Arcam has ever made.
