That chip does exactly what it should do within the concept of the ADI-2 Pro. Its quality is superb, no matter how 'old' it is. It is field proven and matured, considered bug-free, works reliable and solid. Thanks to the second SteadyClock that we implemented only for the SRC input signal it works even better than in many other manufacturer's implementations. On the other hand the new chip is more expensive, and adds no features that would help within its current implementation as simple AES/SPDIF front-end.
So once again tell me why it is 'incredibly unfortunate'?
The reason why I stated that it was unfortunate, is that practically everything else on the ADI-2 Pro is new (ex. why use new converters, if the "old" converters on the ADI-2 work just as well).
As for the new SRC from Asahi Kasei, it does actually add new features that might be useful to some.
For example, the SRC on the ADI-2 Pro can perform sample rate conversion up to 192 Khz, whereas the new SRC from Asahi AK4137EQ (released around the same time as the new converters used in the ADI-2 Pro), can perform sample rate conversions up to 786 Khz (unleashing the full potential of the ADI-2 Pro).
Furthermore, given that SRC is a computationally difficult task, I'd imagine that new chips (released in 2015) have more power / capabilities than the old SRC chips (released in 2010), used by the ADI-2 Pro.
