I appreciate all of the feedback. I did make a point stating there are many YT videos I actually enjoy listening to, and yes, YT is a great way to learn about new and unfamiliar music. However, if anyone can gauge the qualitive nature of a 3K power cord or a 15K power amp, using any one of the videos I am specifically talking about, more power to you. I simply would not trust any of it to make a purchase decision. I do have an assortment of headphones, including Stax, Sony Pro and AKG........YouTube > optical out of my 65 inch LG > dac > pre / power / headphone amp / speakers ( this is my bedroom system, as my main system is audio only ). I hear everything on these videos and what you folks are talking about.....I just cannot make a decision or decipher the value of a piece of gear this way. This is me. As much as I agree that headphones are a wonderful way to hear details, these YT channels I speak of, are imo, poor sounding, and not everything on YT is poor sounding. Again, thank you all for the feedback....Enjoy, be well and stay safe. MrD.
