Analog Devices vs. ESS Technology

Analog Devices AD1955 vs. ESS Technology SABRE32 / ESS90 which is better for audio quality?
It all depends upon how the complete circuit is implemented - board layout, clock. output stage, power supply. 
An accurate DAC can be built using either device. 
What @roberjerman said. The implementation usually matters much more than the chip itself. With that as a given though, some chips are easier to implement than others and ESS are amongst the most difficult - most sensitive to PSU quality for one thing. The AD1955 therefore has a good chance to be better than the ESS.
