Who ever said "time necessarily = progress"? Pretty sure what they say is entropy increases over time. Which is pretty much the opposite. That does not however mean entropy increases uniformly everywhere all the time. We can by intelligent use of energy bring order forth from chaos and create regions where entropy is reversed. Case in point, we can over time learn to create better and better components. Yes, even digital.
This is in fact what you are doing with your example. You took an old CDP, upgraded it with newer parts based on newer understanding, and produced an even better CDP. Happens all the time.
