Of course nothing is perfect. Each device will vary from that ideal but good devices will do it with some design tolerance that helps assure accurate results.
Also of course performance of all devices declines over time so a 10 year old device no longer functions as well as a new one in most cases.
Now, introduce anything that affects the actual light levels detected by absorbing some of it, and if enough is absorbed, a change in the output should occur and could be audible if large enough.
>>>>>I hate to judge before all the facts are in but it appears my explanation of how New Dark Matter works didn’t work on you. No biggie. New Dark Matter doesn’t affect the level of direct reflected laser light, only the level of the background scattered light. All CD players, regardless of cost or age, have this problem with scattered light. As do SACD players, DVD players, and Blu Ray players.
