An advantage of an FPGA based design is that you can control clock jitter everywhere whereas you cannot with DAC chips because you have no control of clock distribution inside the chip. That said, chip DAC designers know what they are doing and they won't allow the on-chip clock to limit resolution. And, further, I think the whole jitter thing is a red herring (see link) and it is only a thing for manufacturers to try to differentiate their products (except that everyone does it these days).I do not believe Rob Watts has a method to measure noise floor modulation (I watched his latest seminar video recently, I will look again to be sure) just he has he cannot measure the diode effects in contacts that he claims are audible. These effects may be important but my point remains why aren't the obvious common-or-garden measurements also first class? If there is a reason where SINAD is compromised to optimize for something not measurable why not say that and make that a feature? And don't forget about the -300dB artifact claim he makes - he sort of shrugs it off saying 'I know it's a big number but I can hear the effect'. That is not good enough, 300dB isn't just a big number it is a very hugely massively enormous number and Rob knows that. At best he is hearing correlation not causation, at worst it is hubris that he thinks his hearing is special.
That all said I've never heard a Chord DAC and if people like them that is great. But one of my mantras is that if you like something then enjoy and don't worry about it being the best objectively because you will be disappointed to find out it is not. Like supporting a football a team, if you insist they win every match then you won't have much fun. And I'm primarily a vinyl listener, a medium that is very compromised objectively but it makes me happy.
