Doesn't work just tried it, dam I so wanted this evaluation board as I'm getting some amazing sounds out of the Harman Kardon HD970 with an transimpedence amp hanging off the AD1955 instead of what comes with it standard.

Cheers George

Now it is a supurb dac with the Transimpedence amp, next will come a Tent XO2 and supply to hopfully make it a supurb stand alone player, because it is a little raw with it's own clock as a player. But with my Teac VRDS-10se Tent XO3 clocked as a transport into it, it is without doubt the best dac I and many of my friends have heard, this is why I would also like to get my hands on a AD1955 evaluation board.

Cheers George

Cool. What's it like to modify? How much is SMD? Any pics of the board?
