There used to be an issue with low output sources, like phono. Most of the 'modern' sources like CD and tape would likely overdrive the power amp. If the power amp has a super low input impedance, that might also be a problem.
For my DAC, standard listening levels are at 1/4 volume to 1/2 volume, depending on the CD and volume I want. On the TVC, the excess signal magnitude is converted to drive, so that at lower volume levels the sound is not depleted.
If you want to hear a mock TVC, that is possible if your source has a built in level control. Turn the level control to zero, and plug the source component in to the power amp. Turn on both and slowly increase the volume level of the source. That will provide a sense of what the preamp is doing to the source signal. If you don't know what you are doing, best not to try this....
