Instantly identifiable, thanks to its pair of elegant VU meters, the AI-501DA belies its retro looks by boasting the latest in high efficiency Class-D amplifier technology. The state of the art modules employed (fed by an oversize toroidal transformer) deliver a colossal 90w per channel, an incredible output in such a physically small amplifier. Yet, despite that, the amp consumes just 0.2w in standby mode and runs so cool that fan ventilation is rendered unnecessary.
Designed to accept digital audio from both Windows and Mac OS-based computers, the amplifier boasts four digital inputs (USB, coaxial, 2 x optical) that feed a 32-bit/192khz precision D/A converter, the BurrBrown PCM1502. Once the supplied USB driver software is installed on your Mac/PC a fully asynchronous digital path is created, allowing low-jitter 24bit/192kHz audio replay. Naturally, there are also two analogue inputs for non computer-based sources.
With speaker connections handled via proper binding posts, a high quality headphone output located on the front panel and full remote control of all functionality (including the other Reference 501 series components) the AI-501DA successfully offers huge versatility (and power) from an unfeasibly tiny enclosure.
