In which schematic?They can oscillate easy. Or run with to high voltage (above +/-15v) without proper cooling.
I am using a lot of opa1611/12 on daily basis in power supplies and audio stages/filters, never one let me down.
It is good to realize that there are no studies or controlled tests that support that statement. Only subjective opinions from people selling such clocks or those having spent so much on them that their opinion is governed by confirmation bias.
So do you have any links to studies or controlled tests? If not then all you have is subjective opinions. No slander in stating that.
So reduced jitter, better clock timing can not be measured in the audio realm as a benefit in an audio DAC? Such a pursuit is unfounded and a total waste of time? It's all audiophool talk and people wasting money?
The whole DAC business sure sounds pretentious and loaded with elevated emotions and feelings based on what I read here. Looks like somebody just got bitter and had to walk away. Yikes.
Perhaps it is best I stay silent and follow my own path?
If we are having fun, I don't see why we have to argue to the point of hating one another.
Scientific measurements and methods are core essentials but a subjective opinion must be tolerated and respected, no?
Exactly, not because you installed some wires that you know better than 'diyforum'
We are discussing anything related to the subject of dacs which cost less and have great sound.
If the emperor has no clothes it is unrealistic to think no one will point it out.
Especially that they need to be expensive - characteristics like dBc/Hz at 1Hz etc. seem to be of no importance.. 🙂

Are there any excellent inexpensive Chinese DACs?
That is the question.So one answer is; Yes, there are many low-cost and effective DAC solutions from China that sound wonderful.
The other answer is; No, there are no good low-budget Chinese DACs because a great DAC costs a lot of money to make with expensive parts, costly methods and associated labor.
If the two answers are true, then we will of course have never never-ending debate and conflicting opinions regardless of the science, sound or subjective experience involved.
But how can two different things that oppose each other be true at the same time?
People can make their points while keeping it civil.
Moreover, we already have discussed the latest research on measuring jitter in dacs at length in other threads, including its present limitations. We have also discussed the cost and complexity of doing publication quality perceptual testing. Almost nobody does it, nor can afford to do it for good, proper, well-known reasons; that includes serious companies like Purifi and ESS.
We have also discussed about the significant variations in sensitivity to clock jitter as a function of different dac architectures.
In addition, we have repeatedly acknowledged that some things about audio perception remain quite subjective.
That's a brief status of the subject at this point in time.
Trying to relitigate a complex subject in every dac thread by throwing out one-liners that take pages of detailed explanations to properly respond to is a well known technique common to internet trolls. The trolling should stop. A polite summary of above items without personal attacks should serve to inform readers while comporting with forum rules.

Perhaps one of the good reasons is that someone stopped to ask "What would be the point ? What do we stand to gain ?"
Same question probably gets asked when thinking about whether to make a new mask for an IC with some flaws in it that customers haven't been told about. Costs about $1,000,000 for a new mask. Usually they don't do it unless they really have to. So long as customers are buying lots of product, why is it necessary to spend that much money? No way its a question unique to dac clocks. Its everywhere in society and in business. Including for situations like, what will your medical insurance policy not cover due to cost versus benefit?

Does any other r2r uses ni-chrom resistors??
They could be an important factor in sound quality

Marcel's RTZ dac uses thin-metal-film resistors, although I did fit one with SMD metal-foil resistors as an experiment. The was a deemed to be a slight benefit with the metal foil, but not enough to be justified by the very high cost.
Also, the Andrea Mori segmented R2R dac I had here used metal film.
