Thanks to Zoran for the advice. I will try to take your advice. But I would like to keep the balance between device cost and efficiency. This reclocker should be several times cheaper than the cost of HQPlayer. I consider HQP to be the benchmark for sound quality. And if this device will approach the cost of HQP, then apparently there is no point in developing it.
A separate shunt regulator for each chip seems redundant. The device from the topic will be assembled to debug the software and evaluate the effectiveness of such a solution. If the result is good, then your advice will also help me a lot. I don't consider myself a good circuit engineer. Therefore, I am ready to learn.

By the way, metastability is measured quite well by an oscilloscope - https://www.siue.edu/~gengel/GALSpro...astability.pdf
