For sale are a pair (right & left channel) of the original Yggdrasil Analog 1 boards, with two Analog Devices AD5791BRUZ DACs per channel. Yggdrasil is no longer available with Analog Devices DACs. So if you have a Yggdrasil with TI DACs and are curious about how the Analog Devices DACs sound, this is a very reasonable priced way to give it a try since Yggdrasils are modular.
