Agree with ivanj on 12-23. I've had a new Oppo 105 for four months, and it's level of performance (for $500) is unheard of - bests my old Cambridge Audio 840C in many ways, including glare. Oppo uses the well reviewed ESS Sabre ES9018 converter, around since 2012. The Absolute Sound 12/14 review of the Oppo 105 states that the engineer modifying the unit "could not improve on the clock or the DAC" so he left them alone. For home audio, I just can't justify going with an outboard DAC now. But, I'd love to hear from any fanatic out there that has done A/B comparisons to the Oppo 105, using newer DAC/chip designs.
