No component, except one that includes loudness or tone controls.
Speaker response changes a bit with volume, but any competent speaker will not change even remotely enough to compensate for how much the response of your ear changes with volume. If your amplifier has high distortion at low volume, you could loose some detail at low volume. Could happen with a pre, but unlikely.
It's your ears/brain that are changing and they are changing by a large amount. Only way to compensate is to change the response of your system. This is one of the problems in audio. Different listening levels all present a much different balance of frequencies.
