Is it worth getting a budget headphone tube amp?

A review of three cheap tube headphone amps.
THERE IS LITTLE POINT IN COMMENTING UNDER THIS VIDEO - because the follow-up video contains the answers to every question that anyone asks under this video.
Below you'll find links to the eBay store that supplied these amps. They sell a lot of different models.

PLEASE DO NOT SEND ME ANY MORE LINKS TO THE TEAR-DOWN VIDEO BY EEVBLOG
Important note. I am fully aware of the tear down video by Dave at EEVBlog of one of these headphone amps, which he kindly performed to lay this matter to rest.
My first video about these headphone amps was uploaded in September 2015, a kind viewer went on to send Dave one of the amps so he could perform a professional tear-down, which he subsequently did in January 2016.
