Spurious free dynamic range of AD5791

At one of the last IEEE conferences it was reported rather poor SFDR of the AD5791 DAC mounted on its evaluation board . The SFDR was of the order of some 80-90 dB. The AD5791 was used to reconstruct a sinusoidal waveform of audio frequency (I do not remember its exact value, probably around 1 kHz).

 

I expressed my hesitation about the corectness of that result, but later discussion lead us to the conclusion, that probably something was wrong with the design of the evaluation board. Could anybody present her/his own SFDR measurement results of this DAC?
