Well, with my understanding, youtube-dl just downloads video/audio from YouTube.  
It does not do anything about transcoding…

So my guess about 74kb/s downloaded audio is really have 74kb/s on YouTube...

With my experience, YouTube is not so good quality with audio.  Almost all of files from YouTube I have downloaded are up to 128kb/s in best case...

Do you mean that you don’t want to talk like above comment?

If so, sorry for that.  I’m not good in English...

I just want to say if the quality of audio/video are limited, you may not get better quality audio/video than original…
