Streaming and download/playback tools can offer greater flexibility. I typically use mpv, though other options are mps-youtube, or for download + playback, youtube-dl and xine, mplayer, mpv, mps, or VLC.

I find I can typically listen at 1.25 - 1.75 readily. Exceptionally poor content I'll bump to 2x. I don't generally go much above that unless I'm fast-forward scanning video for specific content.
