Key specs that matter

One balanced and three single-ended analogue inputs are provided. Frequency response spans a wide 20Hz to 50,000Hz within plus-or-minus 3dB. Signal-to-noise ratio exceeds 95dB, with total harmonic distortion plus noise at or under 0.025%. Weight is 12.3kg, with the built-in AD1955 DAC delivering the high-quality digital conversion the professional-grade AD-66 platform is built around.

Sound and use context

Expect an accomplished performance reflecting the top-end Analog Devices AD1955 DAC chip's audiophile-grade conversion, with the added Bluetooth module extending the professional AD-66 platform's flexibility to wireless sources.

Pairing

The built-in Bluetooth module and AD1955 DAC allow the AD-66D to serve as a comprehensive hub for both wireless and digital sources.
