Logitech software upgrades Hero sensor for mice to 25,600dpi – Computer – News

Just a bit off topic …
That is certainly not always the case.
If you have a class A / B amplifier you can get audible “crossover distortion” at low volume with some amplifiers. One amplifier is certainly not the other.
Class A and D do not have this, but then you still have high and low efficiency speakers that can make a difference.
Incidentally, 100 watts is only 2 times more than 10 watts. So if you really want to see / hear a difference, then you really have to have a seriously heavier amplifier.

It is the combination of amplifier and speakers and even the room they are in (attenuation, etc.) that ensure that it sounds good or not at low volume. Assuming you are testing with the same source.

A sensor with more DPI does make it possible to perform better on uneven surfaces. You then use part of that resolution to determine which way the sensor is going before you actually have to move a pixel on the screen. The higher that resolution, the more accurate this can be and the less you have to move a pixel on your screen. Especially with the high pixel density on modern screens, a higher DPI sensor works better than a low DPI sensor.
