Most my test listening are done on YouTube headphone streaming ...
YT uses lossy compression, so you really can’t be sure what you’re hearing. Add to that the variations of mic preamps and room acoustics and you can’t conclude anything definitive about the components.
Don’t get me wrong - I understand that listening to YT videos can be loads of fun. But if you want to audition an audio component, you’re just as likely to be deceived as enlightened if you’re relying on YT.
You can’t judge the color accuracy of a computer monitor if you’re using a black & white monitor as your tool, or by using a cell phone video of the color monitor.
