I wouldn’t put it that way. The ND555 is a high-fidelity device. If the recording (or mastering) is bad, it can be heard.
What we put in is what we get.
It is not going to make a poor-quality recording sound good. We would no longer be in the HiFi domain.
I have sometimes been surprised by the poverty of some pop/rock masterings…
In such cases, my iPhone and a pair of earbuds are sufficient
