I am in the process of recording a bunch of these videos now comparing speakers and amplifiers. After some testing I have learned that the most important thing in being able to differentiate between speakers and some of the more subtle things in the sound profile is the quality of the microphone used to do the recording. If they aren't using a good, stereo microphone, the quality of the recording won't deliver.
For instance, phone recordings, as good as the iPhone and some android phones are, is not good enough to deliver a good experience. I have learned the actual video is completely pointless and am recording different Video Clips to work in over the top of first rate recorded Audio. That and getting my wife and daughter out of the house for a day so you can't hear Blippi in the background during recordings.
You also have to use headphones. Good headphones make all the difference.
